The automatic fire detectors of the AVENAR detector 4000 series feature a superb accuracy and swiftness in detection. The range includes versions with rotaries, manually and automatically addressable, and versions without rotaries for automatic address setting. Multiple-criteria detectors can support, if single sensors are not sufficient. They have highest stability against deceptive phenomena and response to a broad range of fires. The versions with two optical sensors (dual‑optical) detect the lightest smoke. The versions with heat sensor detect fires with rapid temperature increase or with a maximum temperature value.

FAP-425-O Bosch Smoke Detector
Optical sensor (smoke sensor) The optical sensor uses the scattered-light method. An LED transmits light to the measuring chamber, where it is absorbed by the labyrinth structure. In the event of a fire, smoke enters the measuring chamber and the smoke particles scatter the light from the LED. The amount of light hitting the photo diode is converted into a proportional electrical signal. The dual-optical versions use two optical sensors with different wavelengths. The Dual-Ray technology works with an infrared and a blue LED so that lightest smoke is detected fast and reliably (TF1 and TF9 detection).

Functions Sensor technology and signal processing The individual sensors can be configured in the FSP-5000-RPS programming software. All sensor signals are analysed continuously by the internal evaluation electronics (ISP - Intelligent Signal Processing) and are linked with each other via an inbuilt microprocessor. The link between the sensors means that the combined detectors can also be used where light smoke, steam or dust must be expected during the course of normal operation. Only if the signal combination corresponds to the characteristics of the application site, selected during the programming, the alarm is triggered automatically. This results in less false alarms. In addition, the time of the sensor signals on fire and fault detection is analysed, which leads to high detection reliability for each individual sensor.
