Installation & maintenance
Control equipment
Control unit for smoke detectors
ABAV-S3
With relay contacts for controlling, for example
air handling units.
Function
The unit is designed for DIN-Rail mounting with
LED/indications on the front panel. When a smoke
detector, connected to the ABAV-S3, indicates alarm
for smoke, the ABAV-S3 unit will trigger an alarm
relay, which can be used to stop ventilation fans
and to close fire dampers.
Technical data
At alarm, a red LED is lit and at the same time the
alarm relay drops. When a smoke detector is indicating service alarm the yellow service alarm LED
starts to blink fastly during one minute. After that,
the relay is energized and the LED is showing fixed
yellow light. If the service alarm of the smoke
detector is remedied, the service alarm relay is
de-energized and the yellow LED starts to blink
slowly. Service alarm is an indication that the
smoke detector is contaminated and should
be replaced. Short circuit or interruption will energize the failure relay and at the same time a yellow
LED is lit (for interruption there is a ten seconds
delay).
