Efire NOVA-AHD Isolated Intelligent Addressable Fixed Heat and Heat Rise Detector

Efire NOVA-AHD is an addressable heat detector that evaluates both the ambient temperature exceeding a fixed threshold and rapid temperature rise. It is preferred in dusty or vapor-filled spaces such as kitchens, boiler rooms, parking areas, and workshops where smoke detectors may produce false alarms. It is connected to the loop line with its address; the isolator in its housing prevents a short circuit from affecting the entire line.
