Description

Bosch FAP-425-DO-R

The automatic fire detectors of the AVENAR detector 4000 series feature superb accuracy and swiftness in detection. The range includes versions with rotaries, manually and automatically addressable, and versions without rotaries for automatic address setting.
Multi-criteria detectors can support if single sensors are not sufficient. They have the highest stability against deceptive phenomena and respond to a broad range of fires.
The versions with two optical sensors (dual‑optical) detect the lightest smoke.
The versions with heat sensors detect fires with rapid temperature increases or with a maximum temperature value.
CO fire detectors react promptly to smoldering and suit better for applications with dust, steam, and cooking vapors. Included CO-detection helps to support an more reliable fire detection and leads in parallel to a higher false alarm stability.

Sensor technology and signal processing
The individual sensors can b e configured in the FSP-5000-RPS programming software.
All sensor signals a re analyzed continuously by the internal evaluation electronics (ISP, Intelligent Signal Processing). And a re linked with each other via an inbuilt microprocessor. The link between the sensors means that the combined detectors can b e used where light smoke, and steam are. The Dust must b e expected, normal operation.

If the signal combination corresponds to the characteristics of the application site. Selected the programming, and the alarm i s triggered automatically.
This results in less false alarms.
The time of the sensor signals on fire and fault detection i s analyzed. Which leads to high detection reliability for each sensor.
In the case of the optical and chemical sensors, the response threshold (drift compensation) i s actively adjusted. Manual or time-controlled switch-off of individual sensors is possible for adjustment to extreme interference factors.
