The Beam Smoke Detectors Series OSID – the models OSI-RE-SS and OSI-RIE-00 – work with an optical light beam and a reflector. The combined transmitter/receiver unit is accommodated in the housing. The transmitter emits an infrared beam towards the prism reflector. The reflected signal is analysed by means of a high speed image sensor and the attenuation is evaluated.
The following features of the detectors are remarkable:
- Exact analysis and alarm evaluation through CMOS image sensor
- Detection of clear and dark smoke
- Range of 5 to 100 m
- Detector can be intuitively and easily aligned by means of a movable "eyeball"
- Built-in heater.
