Unit description the cx-105 is a 24vdc passive infrared (pir) occupancy sensor which controls lighting and hvac systems based on occupancy. Pir sensing systems are passive systems which react to changes in infrared energy (moving body heat) within the coverage area. Pir sensors must directly “see” m...

B installation the cx-105 sensors can be mounted to walls or ceilings with the supplied swivel bracket, and the supplied junction box cover plate if n...
5. Insert the tightening screw and nut into the base bracket as illustrated. 6. Use the reference surface angle to adjust the sensor for optimum coverage. When mounted at ten feet, the reference surface angle should be parallel to the wall or the vertical (see figure b). (as the mounting height decr...
Wiring directions caution turn power off at the circuit breaker before installing power packs or sensors. Each wattstopper bz series power pack can supply power for up to 14 cx-105 sensors. When using more sensors than this, multiple power packs are required. Refer to the wiring diagrams on the next...

Sensor adjustment the sensors are factory preset to allow for quick installation in most applications. Ho wever, verification of proper wiring or coverage, or customizing of the sensor’s settings can be done through the following steps. Before starting, make sure the office furniture is installed, l...
Troubleshooting lights do not turn on with occupancy, and the following condition exists: led does not flash: when power is initially applied to the sensor, there is a warm-up period of up to 60 seconds before the led is active. 1. Check that the circuit breaker has been turned back on. 2. Check the...
Unwanted sensor activations (led flashes): possible causes 1. Improper sensor location or angle adjustment causing detection outside of desired coverage area. 2. Sensitivity set too high. 3. Sensor located too close to hvac or vav vents with heavy air flow. Possible solutions 1. Mask the lens to red...
