Ceiling-mount occupancy sensor that both measures PIR (passive infrared radiation) generated by motion and detects sounds typical of human activity Available in two shapes: for...
A series of wall-mounted occupancy detectors designed to switch Douglas 2-wire relays or to signal other systems Several dual-technology models are available that both measure...
Corner-mount occupancy sensor that both measures PIR (passive infrared radiation) generated by motion and detects sounds typical of human activity Combining PIR and sound...
The CM-6-DL is designed for use on high ceilings (15' to 45' above floor level). It utilizes a special PIR lens which has narrower viewing angles than the PIR lens used in the CM...
Measures true ambient light level, ranging from 0 to 6500 footcandles (0 to 65,000 lux) Ideal for control systems requiring accurate light level switching such as skylit areas...
Ceiling-mount occupancy sensor that measures PIR (passive infrared radiation) generated by motion. Sensor lens can be rotated and swiveled for optimum PIR detection Switches...
