Status Inputs (DV-200)

Status inputs (xDyy)

This section explains how to configure the Status Inputs. Each status input is programmed individually according to its use and function.

To configure status inputs, click the Unit Configuration icon () then on the Inputs tab and select Status Inputs.

Status Inputs configuration dialog box

Example from image above: Status input 1D02 is connected to a smoke detector in the rack room. The smoke detector gives a high level when no smoke is detected. When there is smoke, the detector toggles to its low level, a major alarm is sent to recipients of the Major 1 Alarm-Call List, and physical relay 1R07 automatically starts the fire-sprinkler system.

The upper portion of the Status Inputs Configuration dialog box allows you to set the following parameters:

Input Number: Select from the dropdown list the number of the specific status input you wish to configure. Status inputs are all identified by the letter D, followed by one or two digits (up to 64 depending on your Davicom model).

Note: Input Numbers will begin by a digit (1 to 4) to identify a specific Davicom unit when several DV-208/216 units are networked together (SuperMAC). Otherwise it must begin with the digit 1.

Enable: Check this box to enable the input and its automatic actions. When disabled, no reading is taken from the input. Default setting is enabled. You can also enable/disable status inputs by using the Enable and Disable buttons on the DavLink Command Bar (refer to Section 16.1.4 on page 279 of the Reference Manual).

Qualifier: An optional qualifying condition can be set for the selected status input. The condition (other input, output, timer, flag, etc.) must be satisfied (true) in order for the Davicom to execute programmed actions when the status input level toggles to its Active Level. If the qualifying condition is not satisfied, the Davicom will not execute the programmed actions when the input value toggles to its Active Level. Use the xZyyy entry format. Any condition can be inverted by adding the exclamation sign “!” before its identifier (!1S01 for example).

Default Description when Active: Long Unicode description used to describe the status input when at its abnormal Active Level. (Maximum 30 alphanumerical Unicode characters). Refer to Section 4.3.2.5 on page 52 for more details.

Alternate Description when Active: Short ASCII description used to describe the status input when at its abnormal Active Level. (Maximum 18 alphanumerical ASCII characters).

Default Description when Normal: Long Unicode description used to describe the status input when at its normal (inactive) level. (Maximum 30 alphanumerical Unicode characters).

Alternate Description when Normal: Short ASCII description used to describe the status input when at its normal (inactive) level. (Maximum 18 alphanumerical ASCII characters).

The lower portion of the Status Inputs configuration dialog box is divided into four tabs. To configure the Activity Monitoring function, refer to Section 2 Activity monitoring. To configure Vocal Descriptions, refer to this article. For Modbus information, please refer to the Davicom Expansion Module (MEXM) manual and other Support documentation on the Davicom website. To configure automatic Actions, set the following parameters:

Action Type: Select from the dropdown list the action (MIN, MAJ, CMD or QLF) that will automatically be performed by the Davicom unit when a qualifying condition (if applicable) confirms that the value of the status input has toggled from its normal inactive level to its abnormal Active Level. Default action is CMD. Refer to this article for more details.

Alarm-Call List: If you selected MIN or MAJ for Action Type, you need to select a specific Alarm-Call List from the dropdown list (1 to 8). Default value is 1. Refer to this article for more details on alarm-call lists.

Active Level: Select from the dropdown list whether the status input will be active High, or active Low.

Note: High level range is +2.4 and +12 Vdc; Low level range is between –12 and +0.8 Vdc. Default level is set for Active High.

Controlled Relays: The Davicom can act automatically on up to 6 different relays (physical or virtual) when a qualifying condition (if applicable) confirms that the value of a status input has toggled from its normal inactive level to its abnormal Active Level. Use the xRyy identifier for physical relays and xOyyy for virtual relays. By default, relays will react in the Follow operating mode if you do not add any letter to the relay identifier. For the Latch mode, you must add the letter L to the relay identifier. For the Davicom to pulse a relay, you must add the letter P to its identifier. For the Davicom to release a relay, you must add the letter R to its identifier (1R04R for example).

Note: You must make sure each relay is configured for the operating mode you wish to use. You cannot Latch a relay that is configured Pulse Only for example. Refer to this article for more details on relay configuration.

Alarm Signalling On: If you selected the MIN or MAJ Action Type, you need to check this box for the Davicom to initiate the appropriate Alarm-Call Sequence (ACS) when a qualifying condition (if applicable) confirms that the value of the selected status input has toggled from its normal inactive level to its abnormal Active Level. If you do not check this box, no ACS will be initiated, but the Davicom will still log alarms (MAJ and MIN) and commands (CMD), and act on relays. By default this box is checked. Refer to this article for more information on ACS.

Return to Normal Signalling On: If you selected the MIN or MAJ Action Type, you need to check this box if you want the Davicom to initiate the appropriate ACS to report a Return to Normal when the value of the selected status input toggles from its abnormal Active Level to its normal inactive level. If you do not check this box, no ACS will be initiated, but the Davicom will still log the Return to Normal (for MAJ, MIN and CMD) and act on relays. By default this box is checked.

Delay Before Action: To avoid untimely automatic Actions caused by short-duration false alarms, a delay can be programmed before the Davicom responds to a confirmed out-of-limit condition. This sets the minimum duration that an out-of-limit condition must be in effect before the Davicom considers that it is a valid condition and executes the programmed automatic Actions. Default setting is 0 (no delay). You can select a value between 0 and 9999 seconds using the arrows or by typing in the number.

Delay Before Return to Normal To avoid untimely automatic actions caused by short-duration Return to Normal conditions, a delay can be programmed before the Davicom responds to the Return to Normal condition. This sets the minimum duration that the Return to Normal condition must be in effect before the Davicom considers it to be a valid condition, and thus execute the programmed Return to Normal actions. Default setting is 0 (no delay). You can select a value between 0 and 9999 seconds using the arrows or by typing in the number.

Custom Log Davicom units can provide one custom log in addition to the extensive system log. This allows Davicom users to focus-in on desired information. Check this box if you want to record events related to the selected status input in the custom log. By default this box is not checked. This setting also enables periodic data logging (refer to Section 4.7.3.1 on page 138 of the Reference Manual for more details).

Activity monitoring

Each status input has two distinct timers that you can configure/activate. The first timer calculates the length of time the selected status input has been at its current level (whether normal inactive level, or abnormal Active Level), for up to approximately one week. Its value resets every time the level toggles. The second timer cumulates the length of time the selected status inputs has been at its Active Level during the day (resets at midnight). Note that these timers are not the same as the date/day/time timers described in Section 4.3.7 on page 78.

This section will guide you in programming the automatic actions to be performed by the Davicom unit, based on the first activity/inactivity timer. It will also guide you in activating the second daily activity timer. Each status input can have its own activity monitoring function programmed individually according to its use and function.

Status Input Activity Monitoring configuration dialog box

Example from image above: Status input 1D05 is connected to a photosensor on the
antenna tower. When the lights are off during day time, the status input is at its
normal inactive level. When the lights are on during darkness, the status input is at
its Active Level. Every time the lights go off, a timer will monitor the length of time
the status input remains inactive. After 24 hours (1440 minutes) of inactivity, a
major alarm is sent to recipients of the Major 4 Alarm-Call List.

Action Type: Select from the dropdown list the action (MIN, MAJ, CMD or QLF) that will automatically be performed by the Davicom unit when a qualifying condition (if applicable) confirms that the activity/inactivity timer has reached its configured limit time. Refer to this article for more details.

Alarm-Call List: If you selected MIN or MAJ for Action Type, you need to select a specific Alarm-Call List from the dropdown list (1 to 8). Refer to Section 4.4.1 on page 92 for more details on alarm-call lists.

Controlled Relays: The Davicom can act automatically on up to 6 different relays (physical or virtual) when a qualifying condition (if applicable) confirms that the activity/inactivity timer has reached its configured limit time. Use the xRyy identifier for physical relays and xOyyy for virtual relays. By default, relays will react in the Follow operating mode if you do not add any letter to the relay identifier. For the Latch mode, you must add the letter L to the relay identifier. For the Davicom to pulse a relay, you must add the letter P to its identifier. For the Davicom to release a relay, you must add the letter R to its identifier (1R04R for example).

Note: You must make sure each relay is configured for the operating mode you wish to use. You cannot Latch a relay that is configured Pulse Only for example. Refer to this article for more details on relay configuration. This feature is useful to prevent erroneous latching of pulsed relays that could damage external equipment.

Enable Monitoring: Check this box if you want to enable the activity monitoring function and its automatic actions.

Maximum Inactivity Time: Select the Maximum Inactivity Time before the Davicom performs its programmed automatic actions. When the input inactivity timer reaches the configured limit time, the Davicom will perform its programmed automatic actions. Default setting is 0 (no automatic actions based on the input’s inactivity time). You can select a value between 0 and 9999 minutes using the arrows or by typing in the number.

Maximum Activity Time: Select the Maximum Activity Time before the Davicom performs its programmed automatic actions. When the input activity timer reaches the configured limit time, the Davicom will perform its programmed automatic actions. Default setting is 0 (no automatic actions based on the input’s activity time). You can select a value between 0 and 9999 minutes using the arrows or by typing in the number.

Note: The same automatic actions are performed for both the activity and inactivity timers.

Log Daily Active Time: Check this box if you want the Davicom to record the daily cumulative time during which the selected status input has been at its Active Level. Refer to Section 12.9.1 on page 250 of the Reference Manual to view this timer.

Reset at Midnight: Check this box if you want the Davicom to automatically reset the daily cumulative time counter at midnight. The Reset button can be used to reset the counter manually.
