Description of Equipment:
General - FLS-02EC and FLS-02EC-H2 detect smoke using the scattered light, detecting the scattering of thelight reflected by the smoke. There are light emitter (Infrared LED) and the detector (photo-diode) inside, theformer emits the light through the lens, and the latter detects the light scattered by smoke to detect the smokein the hazardous area. This detector outputs include a localized LED, and relays. The installation locations
could be battery rooms, combustible engine storage facilities, chemical plants, etc. FLS-02EC is suitable forGroup IIB, while FLS-02EC-H2 is suitable for Group IIB+H2.
Construction - The construction consists of a single flameproof box, composed of a base and cover, with three
M20 or ½“NPT entries. The base and the cover are constructed of ADC12 Aluminium Alloy. The approximate
weight of the flame detectors is 3 kg. The construction includes internal and external ground, along with a cabletie insertion slot on the outside.
Ratings - FLS-02EC and FLS-02EC-H2 are rated for 24VDC ±10%, 10 mA (standby) and 20 mA (alarm), with
an ambient temperature range of 0°C to +50°C.
