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. 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. AND mode operates as a standard dual technology detector, OR mode will switch to microwave detection in environments where there is a risk of PIR detection being blocked. With Bluewave technology and digital temperature compensation the detector will adjust its sensitivity to the environment. 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 32°C (internal body temperature is 37°C).
