HVG FIRE FIGHTING EQUIPMENT 0044: Marine Explosion-proof Photoelectric Smoke Detector
Marine explosion-proof photoelectric smoke detector is one of most popular and useful fire fighting equipment in the boat. It is a sensitive yet rugged, state-of-the-art, life safety device. The detector is design to operate effectively with both slow smolder-ing and fast burning fires.It uses a solid state infrared emitting diode and a light sensing photovoltaic cell arranged in a laby-rintch assembly. For use in combustible storage facilities, munitions manufacturing,volatile chemical storage ,chemical processing plants or any hazardous location where photoelectric smoke detection is required.
Working Principle
- Each detector contain one set of Form A ( SPST) N/O contacts for connection to the alarm initiation circuit and set of SPST N/C power supervision contacts.
- The detector relay latches in alarm and in addition has a latching LED visible on the outsie of the detector. Detector reset is achieved by momentary interruption of power.
Main Features
- I.Labyringth assembly.
- II.Self-checking components.
- III.Infrared light emitting diode as light source.
- IV.Photoelectric detection technology.
