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 alarm relays, 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 relays
drops. When a smoke detector indicates service alarm the
yellow service alarm LED flashes quickly for 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 (alarm memory). 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 second delay).
If the short circuit or interruption is remedied, the failure relay is
de-energized and the yellow LED starts to blink slowly (alarm
memory).
Test of relays: Press the reset button during five seconds
