FlameGard 5 UV/IR Flame Detector


The FlameGard 5 UV/IR Flame Detector is designed to detect fires and provide alarm outputs directly from the detector while maintaining false alarm immunity.

The FlameGard 5 UV/IR Flame Detector 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. Other features of the FlameGard 5 UV/IR Detector 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, trouble-shooting or programming of the units. HART enables this feature without the need for rewiring.

The continuous optical path monitoring (COPM) self test feature checks both the optical path integrity (window cleanliness) and the detector’s electronic circuitry once every minute.
