PRODUCT DESCRIPTION AND USER'S MANUAL

External Alarms

Four external alarm sources can be connected to the External Alarm module in the repeater. 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 module for external alarms contains a relay output. The relay can be used to indicate the summary status

of the repeater. Each alarm source can be configured to be affecting the relay or not.

Note! The relay status is not 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

makes sure the relay is closed for 3 seconds, then opens for 10 seconds, and finally closes 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.
