دتکتور شعله ضد انفجار برند MSA مدل FL3100H and FL3101H
(MSA Brand UV/ IR and UV Unitized Flame Detectors Models FL3100H / FL3101H)
Description
The General Monitors FL3100H and FL3101H are Ultraviolet/ Infrared and Ultraviolet-only flame detectors designed to detect unwanted fires and provide alarm outputs directly from the detector while maintaining false alarm immunity.
The FL3100H detects fires by monitoring in both the ultraviolet and infrared (UV & IR) spectral ranges making it highly immune to false alarms caused by lightning, arc welding, hot objects and other sources of radiation.
The FL3101H detects in only the ultraviolet (UV) spectral range for optimized speed of response.
Other features of the FL3100H and FL3101H include three alarm/ fault relays, and an RS-485 serial output with Modbus RTU protocol for linking up to 128 detectors in series or 247 with repeaters.
The RS-485 and HART outputs provide status, alarm, fault and other information for operation, troubleshooting or programming of the units.
HART allows this feature without rewiring.
The COPM (Continuous Optical Path Monitoring) self-test feature checks the optical path integrity (window cleanliness)
and the detector’s electronic circuitry once every minute.
