Pyronix KX Dual Technology Alarm PIR Detector has microwave with selectable EOL resistor. Features a dual element pyro-electric sensor with X-band DRO based microwave both of which need to be triggered to set OFF the alarm, this reduces the risk of false alarms Deliver the ideal indoor detection Ideal internal detection for any room. Fit the wired KX15DT and the user can rest assured that they have great detection and protection for their property. Ideal for protection of rooms and offices in commercial environments. Microwave Motion Sensor Pyronix FPTMD15G3-3 Sequential Confirm Detector Grade 3 [FPTMD15G3 EN50131 Compliant Alarm Sensor The use of a PIR and Microwave technology in one means that false alarms are reduced and the detector can maintain intruder catch performance even when the environment experiences changes in temperature With Blue Wave Technology (BWT) and digital temperature compensation the detector will adjust its sensitivity, further enhancing the detectors immunity to false alarms and environmental disturbance. 15m Volumetric detection coverage. KX15DTAM - PIR detector with double technology The detector incorporates 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.
