FireAngel Wireless Module W2 Wireless Smoke Detector

Upon its introduction, the FireAngel ST620 base model was revolutionary in the smoke detector market due to its Thermoptek process and its flat, unique design. Now with the new ST630 wireless smoke detector. What remains is maximum false alarm protection through the evaluation of multiple factors, as well as secure networking across several floors thanks to the integrated wireless module. If a FireAngel unit detects a fire, the alarm is forwarded to all wirelessly connected detectors. The permanently installed lithium battery also ensures reliable and long-lasting fire protection, plus a 10-year manufacturer’s warranty. Design was not overlooked either. The FireAngel addresses the wishes of many users for whom easy installation, comfortable handling, and a flat, inconspicuous appearance are important factors when choosing the right smoke detector.

Beam Paths:

The most common fire detectors are optical or photoelectric smoke detectors. They operate on the scattered light principle (Tyndall effect): Clear air reflects virtually no light. However, if smoke particles are present in the air and thus in the optical chamber (1) of the smoke detector, a test light beam emitted by an infrared LED (5) is scattered by the smoke particles. A portion of this scattered light then falls onto a light-sensitive sensor (photodiode, 4), which is not directly illuminated by the light beam, and the smoke detector activates. Without (smoke) particles in the air, the test light beam cannot reach the photodiode. Illumination of the sensor by light reflected from the housing walls of the LED or by external stray light is prevented by the labyrinth made of black, non-reflective material. Optical smoke detectors are preferably used when predominantly cold smoke is expected at the outbreak of fire (smoldering fire).

A laser detector uses a very bright laser diode instead of a simple light-emitting diode (LED). This system detects even the smallest particle intrusions.
