FLS-02EC(-H2) Explosion Proof Smoke Detector has Division and Zone explosion-proof ratings. This detector is a sensor of the smoke using the scattered light, detecting the scattering of the light reflected by the smoke. There are light emitter (Infrared LED) and the detector (photo-diode) inside, the former emits the light through the lens, and the latter detects the light scattered by smoke to detect the smoke in the hazardous area.
FLS-02EC-H2 is a FM, IECEx and ATEX Approval smoke detector.
-Structure is pressure-resistant, explosion-proof, it can be fitted in a hazardous area. It also tolerates the hydrogen explosion.
-LED provides detector status.
