TECHNICAL DATA
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.
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
requires cleaning. 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).
If the short circuit or interruption is remedied, the failure relay
is de-energized and the yellow LED starts to blink slowly.
Test of relays: Press the reset button during five seconds.

NOTE! The end resistor should always be mounted in
the last detector of the line.
Control unit ABAV-S3 has a failure relay showing failure
in the smoke detector loop. This means that the smoke
detector function is lost/not working. If the failure output
is not transfered to a computer system or alarm panel,
the failure relay contacts should be put in series with the
alarm contacts. If not, the failure will be shown only on
the ABAV-S3.
