How-to: AEC Common Alarm Output

What conditions activates Relay 8 on the first reader board?

Relay 8 is the common alarm output. 

The Common Alarm is triggered from the following events occurring anywhere on the system:

• Door Forced Open
• Door Held Open
• Alarm from an Input Point
• AC Power Failure
• Keypad Duress

 The common alarm output is reset after the event has cleared and the alarm event has been acknowledged in the transaction display of the web interface.
