External Alarms
Four external alarm sources can be connected to the External Alarm and Battery Module. These can be for
instance fire alarms or external door sensors.
The alarm sources must generate a voltage between 12 and 24 VDC. The presence or absence of voltage will
trigger the alarm depending on how alarm thresholds have been configured in the controller software. Each
alarm can also be given a unique name.
The external alarms can be set as “active high” or “active low”.
As for all alarm sources a delay can be set that defines how many seconds an alarm should be in error state
before an alarm is generated
To define names and polarity of the external alarms use the lower part of the Alarm Configuration screen.

Sum Alarm
The External Alarm and Battery Module contains a relay output. The relay can be used to indicate a summary
status of the repeater. Each alarm source can be configured to be affecting the relay or not.
Note! The relay status is never affected by the login / logout alarm parameters.
For installation testing purposes, it is possible to test the open / close function of the relay. This test procedure
closes the relay for 3 seconds, then opens it for 10 seconds, and finally closes it for 3 seconds before going back
to original state.
The relay can be set to close or open to indicate an alarm. This can be changed by changing the polarity.
