Fireguard FG901SHD1_AP Thermal and Thermovelocimetric Detector with Short Circuit Isolator

The Fireguard FG901SHD1_AP is an open-area intelligent addressable heat detector combining static thermal threshold and thermovelocimetric (rate-of-rise) evaluation principles. Built with a high-accuracy thermistor array and microprocessor-controlled algorithms, the unit continuously monitors environmental temperature shifts to ensure reliable early fire warning in areas where smoke, steam, or high dust render optical detectors unsuitable. It features an integrated short-circuit isolator to safeguard loop wiring continuity against fault conditions, soft addressing capability, 360-degree omnidirectional visual status LEDs, and compliance with EN 54-5 and EN 54-17 fire safety standards.
