Description
Control unit for smoke detectors with or without service alarm 230V | ABAV-S3 230V
Description ABAV-S3 230V
The control unit is designed to meet the requirements necessary to provide reliable fire protection in combination with our smoke detectors. Equipped with relay contacts for controlling valves and fans. In addition to Smoke Detection, the ABAV-S3 is equipped with a service alarm relay and a fault alarm relay.
In case of a smoke alarm, a red LED lights up and simultaneously the alarm relay deactivates. When a smoke detector signals a service alarm, the yellow service alarm LED flashes rapidly for one minute. After that, the service alarm relay is energized and the LED remains steadily yellow. If the smoke detector’s service alarm is resolved, the service alarm relay deactivates and the yellow LED flashes slowly: alarm memory.
A short circuit or open circuit will energize the fault relay and alarm relays while the corresponding LED lights up (for open circuit there is a 10-second delay). If the short circuit or open circuit is resolved, the relay deactivates and the LED flashes slowly: alarm memory. To test the relays: hold the reset button for 5 seconds.
