Understanding alarm calls, priorities and sequence

Davicom units can be programmed so that specific events trigger different alarms. Each Davicom unit has 16 possible alarm types: 8 MAJor alarms (MAJ1-MAJ8), and 8 MINor alarms (MIN1-MIN8), and each alarm has an associated Alarm-Call List (ACL). Major Alarms are higher priority and will therefore be processed before Minor Alarms. Each ACL can contain up to 10 recipients, and each recipient can be notified using one of several different means (voice, pager, fax, email, SMS, smartphone, etc.). The ACL must contain at least one entry for an alarm-call sequence to occur for that alarm.

Once an alarm is declared by the Davicom, and as long and there are no blocking calls, an Alarm-Call Sequence (ACS) will be initiated after the user-specified delay in the Alarm& Comm Parameters setup window. This ACS uses the ACL associated with that alarm, and it attempts to notify recipients according to their sequential order in the list. If the Davicom does not receive an Alarm-call Sequence Acknowledgement (ASA) from a recipient, it will wait for a 2nd specified delay before initiating the next call in the ACL. If the Davicom reaches the end of the ACL without receiving an ASA, it will wait for a 3rd specified delay before restarting a new ACS. The specified delays are very important since they allow time for registered users to call back into the Davicom and acknowledge the alarms. If the delays are set too short, the Davicom will monopolize the line with its outgoing calls and prevent incoming calls. These delays are explained in Section 4 Alarm & communications parameters.

If there are many simultaneous alarms, the Alarm-Call Sequences will attempt to contact the recipients of the different Alarm-Call Lists in their programmed order.

There are two ways in which an ACS will terminate:

1– When a recipient, or any Davicom user in control of the Davicom that generated the alarm, acknowledges the ACS, then that ACS is terminated. Refer to this article for important details about alarm acknowledgement.

2– When all the ACS’s have been executed up to the number of times specified without any acknowledgment of the alarms.

Notes on configuring alarms

Normal configuration of alarms should always be done with Virtual Logic Gates (VLG). Assigning a VLG to each of the 16 Major and Minor Alarm-Call Lists facilitates their programming and increases their flexibility tremendously. Since VLG’s can be programmed with practically any combination of metering inputs, status inputs, timers and internal flags they can be used to create complex alarm conditions. You could, for example, have the Davicom call different people on weekends, or at night or even depending on which piece of equipment is defective. Remember that VLG’s can also be nested and cascaded.

To achieve this type of configuration, all physical inputs should be set to be either command (CMD) or qualifier (QLF), depending upon the need to log their activity or not. These commands or qualifiers can then be used in combination with the Timers and System Flags as operands in the VLG screens. Only the VLG’s should be assigned directly to be Major or Minor Alarms. For more information on the configuration of VLGs, refer to this article.

Alarm call lists

To enter recipients into an Alarm-Call List (ACL), click the Alarm-Call Lists button in the Unit Configuration window under the General tab.

First, select the ACL you want to configure among the 16 available ACLs. You have to select the Type (MAJ or MIN) and Alarm List (1 to 8) from the drop-downs. Then, enter up to 10 recipients for the selected ACL. For each recipient, the following fields apply:

Number (#): This is a simple line number and cannot be changed. You must click on the number in order to select a line.

Sequence (Seq): This field gives the sequential order in which the call attempts will be made. Although the telephone numbers/addresses can be entered in any order, this field sets the order in which they are dialled. This allows you to change the order without having to re-enter elements in the list. This value ranges from 1 to 10.

Telephone Number/Address: The complete number/address must be entered (maximum 40 alphanumerical characters including parenthesis, hyphens and commas). Commas are used for 2-second pauses. E-mail addresses must be entered in the foo@bar.com format.

Note: It is possible to use URL addresses in order to send alarms to DavNet or to an SNMP trap manager.

Descriptions: Although the descriptions are optional, it is strongly recommended that they be entered. They can represent names or information about call recipients. The default description can contain up to 30 Unicode characters and the alternate description can be up to 18 ASCII characters. Refer to this article for more details.

Transfer Type (Type): The transmission type must be defined by selecting one of the numbered options between 0 and 15 in the drop-down Transfer Type list.

Selecting 0 disables calls to the corresponding telephone number/address;

1 is for voice telephone calls (used mainly to reach personnel after business hours);

2 is for a computer or terminal;

3 is for standard Fax machines (used mostly for recordkeeping purposes);

4, 5, 6 are for pagers;

7 is for dial-up DavNet;

8 is for e-mail (with attachment);

9 is for DavNet IP;

10 is for SMS text messaging on cell-phones;

11 is for SNMP managers or trap receivers;

12 is for Serial link communication such as UHF/VHF radio link;

13 is for PTT mode over VHF/UHF radio link;

14 is for e-mail (no attachment);

15 is for Smartphone.

Note: Alarm-calls by voice and voice pager can be heard in another language than English (if configured by your local dealer). Alarm-calls sent by fax include the state and value of all Metering and Status Inputs as well as Physical Relays (Alarms sent by fax use the following symbols to describe the current state of all Physical Relays: ✻ = Forced-on, # = Forced-off, % = Pulsed, ! = Energized, $ = Controlled, & = Not controlled.) . Alarm-calls sent by e-mail have both HTML and XML format attachments and include the state and value of all Metering and Status Inputs as well as Physical Relays. Alarm-calls sent by SNMP-v1 traps use enterprise specific codes (SNMP Trap Alarms sent by Davicom units use the enterprise .1.3.6.1.4.1.14665 OID.) (see table below). Note that trap codes only indicate which Alarm-Call List is involved, not the specific input/output that generated the alarm.

Callout: Device This field gives a list of appropriate callout devices. This list can contain Ethernet, modems, or PPP devices according to the Transfer Type selected previously.

Pager Number: Identifies the pager that is associated with the specific entry in the Alarm-Call List. Its parameters are configured under the Alphanumerical Pager tab.

This window allows you to independently configure communications parameters for alphanumeric (Type 6), SMS (Type 10) pagers/cell phones, and Smartphone (Type 15) devices. Note that this window is for pager, cell & smartphone parameter settings only; it does NOT constitute a part of the ACL as such. Devices configured here MUST be listed in the ACL tab for them to be called during an ACS.

Consult your communications service provider for detailed instructions on setting the communication parameters for your alphanumeric pager or SMS settings.

Note also that the Alpha pager settings can often be used to send SMS messages to cell phones via landline if the cellular provider accepts TAP commands.

Alarm & communications parameters

The Alarm & Communications Parameters window contains settings that apply globally to all Alarm Call Lists (ACL). Some of the parameters also apply to other types of calls such as system status or log transfers, IP communications and incoming calls.

To configure the alarm-call parameters, click the Alarm & Comm Parameters button in the Unit Configuration window under the General tab.

Number of Rings (Incoming Calls): The Davicom will answer the incoming call after the selected number of rings. It must be a number between 1 and 9.

Number of Rings (Outgoing Calls): If there is no answer, the call is terminated after the selected number of rings. It must be a number between 1 and 9.

Dialing: Allows you to specify if the phone line connected to the Davicom uses Pulse or Tone (DTMF touch-tone) dialing.

MNP10 Attenuation: Transmission attenuation level can be set to adjust signal strength when the Davicom is communicating via an analog cellular telephone connection.

Enable MNP10: To enable MNP10 mode, this check box must be selected. Used for data transmission over analog cellular telephone line.

Max Connection Speed: This number is the data rate used by the Davicom when sending alarms or transferring reports by modem. It applies to Transfer Types 2, 6, 7 and 10.

Quick Commands: See Appendix F for details on using the Quick Commands wizard.

Group Commands: See Appendix F for details on using the Group Commands wizard

Pause Mode Alarm Call: Allows the Davicom to initiate a Major Alarm each time the Pause mode is activated and to assign it to a specific ACL.

Local Mode Alarm Call: Allows the Davicom to initiate a Major Alarm each time the Local mode is activated and to assign it to a specific ACL.

Delay Before Starting Alarm-Call Sequence: This delay is to allow accumulation of alarms before starting an ACS. It must be a number of seconds between 1 and 99.

Delay Between Each Call: Delay before the next number in the ACL is called when there is no answer from the previous number in the list. Remember to leave sufficient time. We recommend 90 seconds between calls to allow you to call back into the unit. A number between 1 and 999 seconds can be selected.

Delay Before Re-Doing Alarm-Call Sequence: Represents the delay before a new ACS is initiated, if no response was obtained from anyone in the complete ACL the first (or previous) time. A number between 1 and 99 minutes can be selected.

Max Number of Times Done: Represents the number of times the complete ACL will be dialled before stopping if nobody acknowledges the alarms. This field also represents the number of times the Davicom will call to when sending reports/logs for older Davicom MACs (black front panel). A number between 1 and 999 can be selected.

Volume Level: This parameter sets voice volume level in DTMF Telephone mode.

Delay Before Sending Voice Message to Pager: This delay is necessary to account for paging systems that cannot accept messages until a voice greeting has completed. A number between 0 and 99 seconds can be selected.

Delay Before Sending Voice Prompt to Phone: This delay applies to the voice greeting you will hear from the Davicom when you call it (incoming calls). If 0 is selected, the voice prompt will be disabled and the system will enter modem data mode after a 2-second delay (unless the DTMF password is entered during the 2-second pause). If a number greater than 0 is selected, the Davicom will answer the call and the voice greeting will start after the set number of seconds. This delay is sometimes necessary to accommodate certain central telephone exchanges that produce a delay before opening the line. A number between 0 and 99 seconds can be selected.

PTT Relay: This parameter is used to select a physical relay to perform a Push-To-Talk operation when sending an alarm in PTT Mode over the Line out audio jack.

Vocal Acknowledge Before Manual Command: If you check this box, the Davicom unit will ask you to acknowledge all DTMF touch-tone commands before executing them. For example: Do you really want number 5 relay forced-off? Press 1 and # to confirm, or * and # to abort.

Transmit Alarm to DavNet Even if Previously Acknowledged: When this box is checked, alarms are still transmitted to DavNet for archiving purposes, even though they may have been previously acknowledged by a user.

Note: “Max Number of Times Done” and “Delay Between Each Call” are also used for transmission of system status reports, event history logs and battery test reports for older Davicom MACs (black front panel). Refer to Sections 4.6.2 and 4.7 of the Reference Manual for more details on configuring these reports.

E-Mail parameters

The Email parameters window contains parameters that apply globally to all Alarm Call Lists (ACL), system status and log transfers.

To configure the e-mail parameters, click the IP Parameters button in the Unit Configuration window under the General tab and then click the E-Mail tab.

The following parameters are used when contacting the mail server:

Unit E-Mail Address: The Davicom Unit E-Mail Address is used for the “From” address in the E-Mail header.

Send Alert E-Mail To (DHCP Alert Settings): Davicoms can automatically send an E-mail notification to a specified address whenever their IP address is changed by a DHCP server.

POP Host (Incoming mail server): The URL of the POP3 mail server. If the DNS server is configured properly in TCP/IP parameters, the Davicom will perform the name resolution.

Note: Even though the Davicom cannot receive e-mail messages, the POP settings are required because some outgoing mail servers require POP before SMTP authentication.

POP Port (Default 110): The IP port of the POP3 mail server. The actual port number will depend on the provider.

Security (Incoming mail server): Setting of None, SSL, TLS depends on provider.

User Name (Incoming mail server): The username used to logon to the POP3 mail server.

Password (Incoming mail server): The password used to logon to the POP3 mail server.

SMTP Host (Outgoing mail server): The URL of the SMTP mail server. If the DNS server is configured properly in TCP/IP parameters, the Davicom will perform the name resolution.

SMTP Port (Default 25): The IP port of the SMTP mail server. The actual port number will depend on the provider.

Security (Outgoing mail server): Setting of None, SSL, TLS depends on provider.

User Name (Outgoing mail server): The username used to logon to the SMTP mail server. Not required if the SMTP server doesn’t need authentication.

Password (Outgoing mail server): The password used to logon to the SMTP mail server. Not required if the SMTP server doesn’t need authentication.

E-Mail Testing

The Davicom can send test E-mails. This feature is very useful when trying to diagnose E-mail problems caused by anti-spam software and devices, ISP services and relaying-denial settings in servers. This special test function is available directly from within the DavLink e-mail configuration window, the IP Parameters Configuration web page, as well as in VT-100 mode.

Send Test Email: This button allows a test e-mail to be sent directly to a destination e-mail address. The e-mail test result is shown at the end of this section.

To send a test E-mail from within the web page, you must:

1. Connect to the Davicom at the Supervisor level
2. Select Unit Configuration
3. Select IP Parameters
4. Select E-MAIL tab
5. Click the E-MAIL TEST button (see image below)

To send a test E-mail in VT-100, you must:

1. Connect to the Davicom at the Supervisor level in VT-100 mode.
2. Select menu item B: IP Configuration Parameters.
3. Select menu item I: EMAIL Configuration Parameters.
4. Select menu item J: Send test e-mail to, and enter the e-mail address to which you wish to send the test (see image below).

Afterwards, a certain number of messages will appear below line J on the window.

• If the last message indicates “E-mail sent successfully” and if the recipient receives the message, everything works fine.
• If the last message indicates “E-mail sent successfully” and the recipient does NOT receive the message, the problem is between the E-mail server and the recipient since the server acknowledged receipt of the message to the Davicom.
• Finally if the last message does not indicate “E-mail sent successfully”, there is a problem with the E-mail or IP configuration in the Davicom, or with the E-mail server.

The Davicom tries several E-mail connection settings sequentially before declaring that the message cannot be sent:

• Is an SMTP server connection available?
• Is Authentication used?
• Is it a POP before SMTP system?
• Is it Plain SMTP?

If a step fails, the Davicom indicates the failure and proceeds with the next step. See the following figures for details.

The post Alarm Calls (DV-200) appeared first on Davicom Exchange Support Portal (DEX).

The Davicom has the ability to monitor the state of your IP network and of networkenabled devices. This monitoring function is achieved through the use of standard PING commands. Every 1 to 99 minutes, the Davicom sends the configured PING requests to the equipment at the specified IP addresses. If it does NOT receive the standard PING reply to these requests, it sets a PING flag (xNyy) high for the device or address that did not respond. These flags can then be used as operands for Virtual Logic Gates to produce alarms, log events or even, for example, to restart network control equipment if it becomes unstable. To do this the Davicom can use its relays to power-cycle the affected equipment.

To configure PING commands, click the Unit Configuration icon () then the General tab in DavLink and select IP Parameters in the Ping Configuration tab.

Note: Davicom users with Operator access level do not have access to the IP Parameters configuration screen. Administrators can only access the Ping Configuration tab.

To configure a PING command, select the ping ID (click the ID number) in the upper section of the dialog box, set the following parameters in the lower part and then click Change.

ID: Ping identification number. (xNyy)

Default Description: Long Unicode description for each ping. (Maximum 30 alphanumerical Unicode characters). Refer to this article for more details.

Alternate Description: Short ASCII description for each ping. (Maximum 18 alphanumerical ASCII characters).

Ping Address: Required field if you want your Davicom unit to be able to ping your IP network and network-enabled devices. A unique number consisting of 4 parts separated by dots or an URL (ex: 172.16.202.131 or www.google.com).

Note: Ensure the address is valid and that it can normally be accessed in your on-site network. If the address used is a public Internet address, ping fail flags can be randomly generated, especially if the server blocks ping requests.

Ping Period Required field to set the period interval of the equipment to be polled. This parameter ranges from 1 to 99 minutes. Default value is 1 minute.

To configure more PING commands, select another ping ID (click the ID number), set its parameters and then click Change.

To delete PING commands, select the appropriate ping ID (click the ID number) and click Delete.

Once you are done with the configuration of PING commands, click OK. When asked if you wish to upgrade the Davicom’s memory, click Yes.

Should you ever run into a situation where you have a weak (lower than about 2.3 volts) or dead Davicom 2L76 RAM battery and don’t have an identical replacement readily available, you can use two of the single- cell 1.5 volt battery types listed above and you will be up and running in no time.

Note that the small contact is the minus ( – ) and that it must face towards the rear of the unit when installed in the socket.

It is important to understand what information is stored in a Davicom unit, versus that which is stored by DavLink in a computer. This way, when you communicate with a Davicom unit using a telephone, you will know what information the Davicom can provide by itself. Also, when you use DavLink on someone else’s computer, you will have access to all the information stored in the Davicom unit, but will be aware of what might not be available on that other computer.

Connect/Disconnect versus Logon/Logoff

IMPORTANT NOTE: For increased security, each Davicom unit and each installation of DavLink have their own distinct logons and information storage.

When you connect to a Davicom unit using a touch-tone telephone or the Connect icon (), you have to provide a valid Davicom username and password. The Davicom unit will compare the user data that is provided with authorized users that have been stored in its memory.

When you start the DavLink software, you have the option of logging-on to the program by clicking the Logon/Logoff icon (). This logon gives you access to the DavLink edit mode which allows you to create, edit and delete personalized monitoring and control screens called workspaces.

Logging-on to DavLink also gives you access to your site directory (). The directory is a quick and convenient way to connect to any of your Davicom units without having to remember phone numbers/addresses, usernames and passwords. Although logging on to the DavLink software allows you to connect to Davicom units via the directory, these two functions (Logon and Connect) are completely independent and each use different usernames, access levels and passwords. The database in DavLink contains both the usernames and passwords to logon to the DavLink directory, as well as the usernames and passwords to connect to each individual Davicom unit.

In order to avoid any security breach, you should disconnect from the Davicom unit once you are done by clicking the Disconnect icon (), or with the 99# touch-tone command. You should also logoff from DavLink (if applicable) using the Logon/Logoff icon ().

Information stored in the unit’s memory versus that in your computer

Davicom unit usernames and passwords, site identification, input/output configuration, automatic actions, alarm settings and calibration data are all stored in the memory of the remote site unit, and can be saved as a cfg file.

All Dial Directory and DavLink User Information, as well as Workspace (mcw) files are stored directly in your computer.

In the past, we recommended that Gmail’s “Less Secure App Access” setting be used in the
Google account used to send emails from a Davicom unit through Gmail servers. The possibility
of using that setting will be discontinued by Google on May 30th, 2022.

The new recommended method to send email from your Davicom units is to enable Two Step
Verification (2SV) and the “Sign in with App Passwords” method.

NOTE: this method can be used to send email from a Davicom unit without the 2nd step in
the 2SV process.

Before being able to see the “Sign In With App Passwords” fields, you must first enable 2SV in
your Google Account Security settings. You will be sent a Verification Code to your email or cell
phone during this set-up process. Once you’ve accessed your account, you will then see the
“Sign In With App Passwords” fields.

Activate 2-Step Verification

1. Open your Google Account.
2. In the navigation panel, select Security.
3. Under “Signing in to Google,” select 2-Step Verification > Get started.
4. Follow the on-screen steps.
5. Do not select any devices.

Sign in with App Passwords

Create & use App Passwords

1. Go to your Google Account.
2. Select Security.
3. Under “Signing in to Google,” select App Passwords. You may need to sign in. If you
   don’t have this option, it might be because:
   1. 2-Step Verification is not set up for your account.
   2. 2-Step Verification is only set up for security keys.
   3. Your account is through work, school, or other organization.
   4. You turned on Advanced Protection.
4. At the bottom, choose Select app and choose Other. Name it Davicom xyx, then > Generate.
5. The App Password is the 16-character code in the yellow bar on your device.
6. Copy and paste it into the Email Password field on your Davicom unit.
7. Save a copy in your records.
8. Tap Done.

You can generate different passwords for different devices, all in your same Google
Account. Be sure to give them names that will allow you to keep track of them. Also, once
the password is generated by Google, make sure you keep a copy somewhere in your
records because it will not be visible after you enter it into your Davicom unit.

App Passwords revoked after password change

To help protect your account, Google revokes your App Passwords when you change your
Google Account password. To continue to use an app with your Google Account, create a new
App Password.

Once an alarm is triggered by the Davicom, an Alarm-Call Sequence (ACS) is initiated. This ACS uses the Alarm-Call List (ACL) associated with that alarm, and it becomes the Davicom’s top priority to notify recipients according to their sequential order in the ACL. The Davicom will keep notifying recipients until the alarm is acknowledged (or until the ACS has been executed up to the number of times specified without anybody acknowledging the alarm). Refer to Section 1 of this article for more details.

Any user connected to the Davicom and in control of it at the time an alarm is generated will first get the alarm message and will be asked to acknowledge it. This situation might also occur if the user is able to connect and gain control in-between two alarm calls.

The Davicom will accept acknowledgement by any valid Davicom user, except for viewer-level users.

If they occur, multiple alarms will be grouped according to their ACL, and each group will require an independent acknowledgement. Groupings are presented in the MAJ1 to MAJ8, MIN1 to MIN8 order, not chronologically. But in each group, alarms are presented in a chronological order (most recent first).

Note: Unless the alarms must be sent faster, we recommend you set delays to a minimum of 30 seconds for both the alarm and return-to-normal signalling. This ensures glitches and short annoyance alarms are filtered out. It also ensures that you aren’t advised of a return-to-normal condition without having previously received an actual alarm.

Section 2 below explains the consequences for a Davicom user when acknowledging an ACS. Section 3 describes the procedure to acknowledge alarms using DavLink. Section 4 describes the procedure to acknowledge alarms using a touch-tone telephone.

Understanding the acknowledgement of alarm-calls

Any Davicom user in control of a Davicom unit that generated alarms can acknowledge one or more ACSs, and that user has 30 seconds to decide whether to acknowledge an ACS before being disconnected by the Davicom. When an ACS is acknowledged, the ACS is instantly terminated. By acknowledging one or more ACS’s a user must be aware that he is taking responsibility for the Alarm(s) that were generated by the Davicom.

Acknowledging using DavLink

DavLink allow users to acknowledge alarms generated by a Davicom unit. The procedure is slightly different for Major and Minor alarms.

Major alarm acknowledgement

Events related to Major Alarms are grouped by ACS according to their ACL. Each ACS related to a MAJx ACL is acknowledged in the MAJ1 to MAJ8 order using an Alarm-call Sequence Acknowledge (ASA) command. Image below shows a typical Major Alarm acknowledgement window.

Clicking Yes acknowledges and terminates that ACS. Clicking No instantly disconnects you from the Davicom so that the unit can try to reach other recipients. If you do not take any action, the Davicom will automatically disconnect you after 30 seconds and call the next recipient.

Number (#) – This is a simple line number, #1 being the most recent event.

Note: Only the 10 most recent events are displayed. The ASA command acknowledges all events related to the ACS, including those not shown.

Date-Time – The date (yyyy-mm-dd) followed by the time (hh:mm:ss) at which the event occurred. Note that the date and time displayed are those configured in the Davicom unit. The time takes into account any Delay Before Action that might have been configured.

ID – Input that caused the event, displayed in the xZyyy format.

Note: Only the inputs with the Signalling On Alarm box checked will be displayed upon alarm.

Event – Since each ACS has its own acknowledgement window, you will either see the ACL related to the ACS, or NORMAL indicating a Return to Normal.

Description – Depending on your language selection, the long Unicode or short ASCII description for the input that generated the alarm will be displayed. For inputs with different descriptions for the active (alarm) and inactive (normal) state, the description related to the event will be displayed. Refer to Section 1.6 of this article for more details.

Level – The value of the input. This value represents the first Davicom reading once a limit is reached, not the current, maximal or any other value.

If you configured inputs with the Signalling On Return to Normal, you will also have to acknowledge Return to Normal messages related to major alarms. The Return to Normal messages for a specific MAJx ACS might be combined with alarms also related to that ACS, or might appear in a separate window. Return to Normal after major alarms are acknowledged exactly the same way as for Major Alarms.

Minor alarm acknowledgement

Once all Major Alarms, and their Returns to Normal (if applicable), have been acknowledged, DavLink will display Minor Alarm acknowledgement windows in the MIN1 to MIN8 order.

Each ACS related to a MINx ACL is acknowledged using an OK confirmation command. Clicking OK acknowledges and terminates that ACS. If you do not take any action, the Davicom will automatically disconnect you after 30 seconds and call the next recipient. Refer to Section 3.1 above for a complete description of the fields.

If you configured inputs with the Signalling On Return to Normal, you will also have to acknowledge Return to Normal messages related to minor alarms. The Return to Normal messages for a specific MINx ACS might be combined with alarms also related to that ACS, or might appear in a separate window. Return to Normal after minor alarms are acknowledged exactly the same way as for Minor Alarms.

Acknowledging using a touch-tone telephone

Davicom units allow users to acknowledge alarms using a touch-tone telephone.

Tip: When multiple alarms occur, the Davicom vocal message can be rather long (up to 10 events). Pressing the star (✱) key one or more times will stop the message (as soon as the tone is heard within the small interval between two spoken words). Some telephones provide a constant tone sound. In such a case, you can keep the star (✱) key pressed until the message stops. This allows you to quickly acknowledge without having to hear the entire message.

Important: You must wait for the Davicom voice response system to complete its sentence before entering your touch-tone commands. Any touch-tone command entered while the Davicom is speaking will not be considered.

The procedure is slightly different for Major and Minor alarms.

Major alarm acknowledgement

Vocal messages related to Major Alarms are grouped by ACS according to their ACL, in the MAJ1 to MAJ8 order. When a Davicom unit calls a recipient of a MAJx ACL to report a major alarm, the Davicom voice response system will say for example: “Major Alarm One, Digital Input Zero Six, Please enter ASA command” and will wait 6 seconds for an acknowledgement.

Each ACS related to a MAJx ACL is acknowledged using an Alarm-call Sequence Acknowledge (ASA) command. Pressing 272# (representing the letters A S A on the telephone keypad) acknowledges and terminates that ACS. Pressing 99# will disconnect you from the Davicom unit, allowing the Davicom unit to try to reach other recipients. Refer to this article for the complete list of touch-tone commands.

If you configured inputs with the Signalling On Return to Normal, you will also have to acknowledge Return to Normal messages related to major alarms. The Return to Normal messages (for example “Normal Status, Digital Input Zero Six, Please enter ASA command”) for a specific MAJx ACS might be combined with alarms also related to that ACS, or might be mentioned in a separate message. Return to Normal after major alarms are acknowledged exactly the same way as for Major Alarms.

If you do not take any action during the 6-second delay following a message, the Davicom voice response system will repeat the same message a second time and will wait another 6 seconds for an acknowledgement. Finally, the Davicom voice response system will repeat the same message a third time and will wait 6 seconds before disconnecting you in order to call the next recipient.

Minor alarm acknowledgement

Once all Major Alarms, and their Return to Normal (if applicable), have been acknowledged, the Davicom voice response system will mention Minor Alarms in the MIN1 to MIN8 order. When a Davicom unit calls a recipient of a MINx ACL to report a minor alarm, the Davicom voice response system will say for example: “Minor Alarm One, Analog Input Zero Three, Press one and pound key to confirm, or star and pound key to abort” and will wait 6 seconds for an acknowledgement.

Each ACS related to a MINx ACL is acknowledged using a confirmation command. Pressing 1# acknowledges and terminates that ACS. Pressing ✱# will disconnect you from the Davicom unit, allowing the Davicom unit to reach other recipients. Refer to this article for the complete list of touch-tone commands.

If you configured inputs with the Signalling On Return to Normal, you will also have to acknowledge Return to Normal messages related to minor alarms. The Return to Normal messages (for example “Normal Status, Analog Input Zero Three, Press one and pound key to confirm, or star and pound key to abort”) for a specific MINx ACS might be combined with alarms also related to that ACS, or might be mentioned in a separate message. Return to Normal after minor alarms are acknowledged exactly the same way as for Minor Alarms.

If you do not take any action during the 6-second delay following a message, the Davicom voice response system will repeat the same message a second time and will wait another 6 seconds for an acknowledgement. Finally, the Davicom voice response system will repeat the same message a third time and will wait 6 seconds before disconnecting you in order to call the next recipient.
