With Blue Wave Technology, and digital temperature compensation the KX15DQ will automatically recognise any environmental changes and adjust accordingly.15m Volumetric detection coverage. Ideal for protection of rooms, offices etc.The detectors incorporate selectable alarm resistor values of 6K8, 5K6, 4K7 &1K & tamper values of 5K6, 4K7, 2K2 and 1K catering for most control panels on the market.Depending on the environment condition, the detector will automatically adjust the sensitivity.When the product is used in a hot environment this technology digitally adjusts the detector’s sensitivity allowing it to maintain its range even when the background room temperature is almost equal to the external body temperature of 32ºC (internal body temperature = 37ºC).Supplied with both wall & ceiling mount brackets which provides access for up to two 8 core cables (Tamper kit optional).Protects from possible infestation from insects, shields air movement in front of the pyro-electric sensor and protects against adverse reflections from inside the detector housing.
