Bosch FAS-420-TM Aspirating Smoke Detector LSN improved version with LED displays for operating mode, malfunction and alarm

The FAS-420-TM Series Aspirating Smoke Detectors are specially designed for direct connection to the Local SecurityNetwork improved version with the extended range of features. These active fire detection systems are for early fire detection in zone and equipment protection, as well as for the monitoring of air-conditioning units or ducts. The exact location of the fire can be pinpointed using the innovative fire source identification. The aspirating smoke detectors are fitted with the latest fire detection technology. Their resistance to contamination, the temperature compensation of the sensor signals and initialization in relation to air pressure ensure reliable operation even under difficult environmental conditions. For connecting to the fire panels FPA-5000 and FPA-1200 with LSN improved technology. High deceptive alarm immunity with intelligent LOGIC·SENS signal processing. Innovative fire source identification technology allows the exact location of the fire to be pinpointed by monitoring up to five distinct zones. Innovative airflow monitoring including single-hole monitoring detects obstruction and breakage. Installation and commissioning made easy by plugand- play function. Easy to diagnose using FAS-ASD-DIAG Diagnostic Software. Simple implementation of the pipe system planning through patented aspiration reducing film sheets. Preservation of LSN loop functions in the event of wire interruption or short-circuit through two integrated isolators
