UNIT DESCRIPTION The Watt Stopper CI-305 360° passive infrared (PIR) occupancy sensors turn lighting systems on and off based on occupancy. SmartSet™ technology allows the sensor to be installed with minimal adjustments. SmartSet automatically adjusts the time delay and PIR sensitivity to usage patterns in the controlled space. The sensors can be configured to turn lighting on, and hold it on as long as the sensor detects occupancy.
PLACEMENT GUIDELINES Depending upon obstacles such as furniture or partitions, the area of coverage may be less or more than the sensing distances shown in the coverage pattern. This must be considered when planning the number of sensors and their placement. It is also recommended to place the sensor 4 to 6 feet away from air supply ducts as rapid air currents or the differences in temperatures may cause false activations. Mount the sensor to the ceiling.
WIRING DIRECTIONS CAUTION TURN POWER OFF AT THE CIRCUIT BREAKER BEFORE INSTALLING POWER PACKS OR SENSORS. Each Watt Stopper B series power pack can supply power for up to 12 CI-305 sensors. Each Watt Stopper BZ series power pack can supply power for 16 CI-305 sensors. When using more sensors than this, multiple power packs are required. Refer to the wiring diagram on the next page for the following procedures: Connect the low voltage: • RED wire (+24VDC) from power pack to the +2 4 V terminal on the sensor.

MOUNTING THE SENSOR Directly to Ceiling 1. Attach the plastic spring clips to the edge of the sensor in the slots provided. 2. Cut a 3.5” to 4” round hole in the acoustic ceiling tile at the mounting location. A 3.5” hole is recommended for a secure fit . 3. Pull the low voltage wire from the power pack to the sensor through the hole. 4. Connect the low voltage wires to the appropriate terminals on the sensor. 5. Push the sensor up through the hole until the Spring Clips hold the sensor securely in place.
SENSOR ADJUSTMENT The sensors are factory preset to allow for quick installation in most applications. Verification of proper wiring or coverage, or customizing the sensor’s settings can be done using the following procedures. To make adjustments, open the Front Cover with a small screwdriver. There is a 30 second warm-up period when power is fir s t applied.
DIP SWITCH SETTING DIP Switch Setting Chart The CI-305 has 7 DIP switches under the cover. They are used to set manual/automatic on/off functions, time delay and sensor activation LED settings. On Mode: Switch 1 The Manual ON function is facilitated by installing a momentary switch such as a Watt Stopper LVS-1 Momentary Toggle Switch, or RS2-3 Low Voltage Momentary Switch. This switch connects to the sensor’s Manual (Man.) Switch and Common terminals as shown in the wiring diagram.
Override: Switch 2 To override all sensor functions, set DIP switch 2 to the ON position. The green LED will come on and stay on for the duration of the override. This bypasses the occupancy detection control functions of the sensor, but still allows the lights to be manually controlled with a light switch, if one is installed. Time Delay: Switches 3, 4, 5 The sensor will hold the lights on as long as occupancy is detected. The time delay countdown starts when no motion is detected.
TROUBLESHOOTING CAUTION TURN POWER OFF AT THE CIRCUIT BREAKER BEFORE WORKING WITH OR NEAR HIGH VOLTAGE. Lights do not turn on with occupancy, and the following condition exists: • PIR Activity LED does not flash: NOTE: When power is initially applied to the sensor, there is a warm-up period of up to 30 seconds before the LED is active. 1. Check that the circuit breaker has been turned back on. 2. Make sure that the PIR Sensitivity is set for Max/Smartset (DIP switch 7 on). 3.
Unwanted Sensor Activations (LED flashes): • Possible causes 1. Improper sensor location or inadequate masking causing detection outside of desired coverage area. 2. The PIR sensitivity may be set too high. 3. Sensor located too close to HVAC or VAV vents with heavy air flo w. • Possible solutions 1. Mask the lens to reduce PIR coverage (see “Masking the PIR Lens”, under “Placement Guidelines”). 2. Set DIP switch 7 to OFF and see if the excess activations stop. 3. Relocate the sensor.
