Common Alarm Output
7.1
Overview
The Access Easy Controller provides a Common Alarm output that can be used to provide a
hand-off to an intrusion alarm system, such as a Focus 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 out-
put consists of form-C type dry contacts rated to handle 1A @ 24 VDC Resistive. Refer to the
wiring diagram for 4-reader board 1 for wiring information on the Common Alarm output.
The Common Alarm output will activate automatically whenever the Access Easy Controller
detects any of the following conditions.
X
Door Forced Open is detected from a reader controlled door,
X
Door Held Open is detected from a reader controlled door,
X
Alarm is detected from an input point on an 8-Input/Output card board,
X
AC Power Failure to controller is detected,
X
Controller Tamper is activated, or
X
Duress condition is signalled from a keypad reader.
Once activated, the Common Alarm output will remain activated until the condition that
caused activation returns to normal. In the event multiple alarms exist within the controller,
the Common Alarm output will remain activated until all alarm conditions have restored.
A duress condition is an exception to the processing explained in the previous paragraph. The
Common Alarm output will activate immediately when any user of a card reader signals a
duress situation from the reader's keyboard. But, because a duress event does not have a res-
toration associated with it, the Common Alarm output will remain activated until the duress
alarm is acknowledged from the View Activity screen.
The rest of the Chapter describes each type of alarm that will trigger the Common Alarm out-
put.
7.2
Alarm (All Input Points)
These Input Points, ranging from address 33 to 64, when Armed by schedules or manually via
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.
7.3
Door Forced Opened and Door Held Opened
These two transactions are related to the 16 Readers (Doors). Should there be such a transac-
tion, the Common Alarm Output will be triggered and will only be restored when the Door
Contact is closed i.e. the door is closed.
