Product description
FAS-420-TP2-SL is an analogue addressable detector that detects smoke using a two-pipe air sampling system. It uses LEDs to indicate operating, fault and alarm states; its quiet fan makes it suitable for use in noise-sensitive areas.
Key features
- Supports two-pipe air-sampling systems
- LED indicators for operating, fault and alarm conditions
- High immunity to false alarms with intelligent signal processing
- Airflow monitoring detects blockages and breaks
- Integrated isolators maintain LSN loop functionality in the event of a cable break or short circuit
- Sound level 38 dB(A); reducible to 34 dB(A) with an additional sound absorber
