Common Alarm Output
13.1
Overview
The AEC2.1 provides a Common Alarm output that can be used to provide a hand-off to an
extended alarm system, whenever an alarm condition is detected by the controller.
The Common Alarm output is available from the last relay on the first 4-Reader board. The
output consists of Form-C type dry contacts rated to handle 1A @ 24 VDC Resistive. Refer to
,
page 23
for wiring information on the Common Alarm output.
The Common Alarm output will activate automatically whenever the AEC2.1 detects any of the
following conditions:
–
Door Forced Open is detected from a reader controlled door,
–
Door Held Open is detected from a reader controlled door,
–
Alarm is detected from an input point on an 8-IO board,
–
AC Power Failure to controller is detected,
–
Controller Tamper is activated, or
–
Duress condition is signalled from a keypad reader.
Once activated, the Common Alarm output will remain activated until the condition that
caused alarm returns to normal. In the event multiple alarms exist within the controller, the
Common Alarm output will remain activated till all alarm conditions are restored.
A duress condition is an exception to the processing explained in the previous paragraph. The
Common Alarm output will activate immediately when any cardholder of a card reader, signals
a duress situation from the reader's keyboard. But, because a duress event does not have a
restoration associated with it, the Common Alarm output will remain activated until the duress
alarm is acknowledged from the transactions screen.
The headings below describe the type of alarm that will trigger the Common Alarm output.
13.2
Alarm (All Input Points)
These Input Points, ranging from address 33 to 64, when Armed by schedules or manually
through a dedicated Arm/Disarm Reader or through the web page could monitor the input
status.
Once triggered, the Common Alarm Output will be turned on until the Input Point is restored
or the input is Disarmed.
13.3
Door Forced Open and Door Held Open
These two transactions are related to the 32 Readers (Doors). When there be such a
transaction, the Common Alarm Output triggers and is restored when the Door Contact is
closed i.e. the door is closed.
13.4
Panel AC Failure
When there is a power outage and the controller is taking power from the backup battery, the
message Panel AC Failure, is sent to the Transactions web page. The Common Alarm Output is
triggered on and is restored when the main power supply is restored.
