OVERVIEW
FLS-02EC(-H2) Explosin 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. This detector outputs include a localized LED, and relays.
An example of the installation location of this detector is as follows:
Battery rooms
Combustible storage facilities
Chemical plants
Engine room, etc
2.
FEATURE
Since the structure is pressure-resistant, explosion-proof, it can be fitted in a hazardous area
It also tolerates the hydrogen explosion.
FM Approved for use in Class I, Division 2 hazardous locations. and FM Approvals for smoke
detector.
IECEx & ATEX Zone approved
LED provides detector status.
