AC Power Fail
The AC Power Fail input provides a way to monitor the main AC utility power through small wallwart power supply (included with your Cortex unit). If the utility power fails, the input becomes active and an alarm can be generated (if it has been so configured).
The AC Power fail input is associated with the flag Identifier named 1P1.
Please see this article for details about the generic Main screen, Description screen and Vocal Description screen.
Below is the Action menu screen of the AC Power Fail input.
1 – ID: ID of this Input (1P1)
2 – I/O DESCRIPTION RETRIEVAL: Click to retrieve and display the current normal description of that ID. Normally hidden to minimize data transfers on low speed or high fee data connections. The Descriptions window for the AC Power flag is shown below :
3 – ACTION TYPE: Selects the action type that will happen when an out-of-limit condition occurs. 3 types are available: Major alarm, Minor alarm, and Command (CMD). On CMD, no alarm will be triggered. Use this Action when you want to take actions without triggering any alarms.
4 – QUALIFIER: Qualifying element (operand) which can be any input, output, flag, timer, SNMP GET, Logic Gate, etc. Essentially any ID in the Cortex can be used to mute or unmute the input to prevent it from taking any action. When the Qualifier is active, the input will be monitored and be able to generate alarms. When the qualifier is non-active (or normal), the input will be muted and it will not be able to generate an alarm. To invert the Qualifier’s level, simply put a ! in front of its ID. For example, use !1D01 to invert it. Leave the Qualifier field blank for a “don’t care” condition.
5 – CONTROLLED OUTPUT: Outputs to be controlled (on/off) based on the state of this input. The two output types allowed are relays (both physical and virtual) and SNMP SETs. For the relays, adding a P suffix will Pulse the relay (ex: 1R01P), L will Latch it and R will Release it.
6 – DELAY BEFORE ACTION: Delay before the input changes into an active state when an out-of-limit condition occurs. Prevents glitches from setting-off any alarms.
7 – DELAY BEFORE RETURN TO NORMAL: Delay before the input returns to a normal state once an out-of-limit condition is over. Prevents too-brief returns-to-normal from causing multiple repeated alarms.
8 – ENABLE: Enable / disable the input. Useful to deactivate an input, without losing all its settings, when the input is causing intermittent problems or nuisance alarms.
9 – SYSTEM LOG: Log the input’s activity in the System Log. Useful when inputs do not need to be logged, but are required for day-to-day operation.
10 – SIGNALLING ON – ALARM: Enables / disables alarm signalling. When checked, any out-of-limit condition will automatically generate an alarm. When unchecked, no alarm will be triggered when an out-of-limit condition occurs.
11 – SIGNALLING ON – RETURN TO NORMAL: Enables / disables Return To Normal signalling. When checked, a notification will be generated when the input changes back to its normal state after an out-of-limit alarm condition. When unchecked, no notification will be sent when the initial alarm condition returns to normal.
12 – REFRESH / READ: Refresh / read the screen content.
13 – SAVE / WRITE: Save the screen content.
14 – EXIT: Exit menu.
