Bosch AVENAR 4000 Heat Detector

The Bosch AVENAR 4000 Heat Detector is an addressable thermal fire detector engineered for environments where smoke-based detection is impractical — such as kitchens, parking garages, dusty industrial areas, and boiler rooms. It monitors ambient temperature for both fixed temperature thresholds and rate-of-rise conditions, triggering an alarm when either criterion is met for rapid response to fast-developing fires. Compatible with the Bosch FPA-1000 and AVENAR Panel 2000 via the LSN addressable loop, each unit is individually identifiable for precise zone management. The integrated short-circuit isolator protects loop continuity in the event of a line fault. Its robust construction ensures reliable performance in harsh or high-humidity environments. Compliant with EN54-5 standards and suitable for BFP-compliant FDAS installations across commercial, industrial, and institutional buildings in the Philippines.
