Siemens DO1152A Optical Smoke Detector

Feature & Principle

It adopts photoelectric optical sensing principle. When smoke enters the detection chamber, light scattering triggers the detector signal. Built-in short-circuit isolator prevents single line fault from crashing the whole loop. It communicates with fire alarm controller, sends alarm signal once smoke concentration reaches threshold, with low false alarm performance.
