INTRODUCTION
Ceiling Mounted Occupancy Sensors are ideal for use in business and office settings to accurately detect occupancy and automatically control lighting. The ceiling mount design of these low profile sensors allows the greatest possible motion sensitivity. An adjustment panel is conveniently located on the front of the sensor, providing ready access to setting controls after the sensor is installed.

Always use a properly rated voltage sensing device to confirm that power is off.
- Attach the adapter plate to a standard 3.5 in. (8.9cm). ceiling junction box using the two #8 x 32 screws supplied.
- Wire the sensor according to the wiring diagram; follow all applicable national and local electrical codes.
- Attach the sensor to the adapter plate by inserting the pins on the adapter plate into the keyholes on the back of the sensor. Rotate the sensor clockwise until it locks in place.
Flush Mounting
KEY: A. Keyhole pin, B. Mounting screw, C. Ceiling, D. Mounting adapter plate. Note: Rotate clockwise.

Always use a properly rated voltage sensing device to confirm that power is off.
- Drill a hole large enough to accommodate wiring at the mounting location.
- Attach the adapter plate to the ceiling using a secure method, such as with screws and wall anchors (not provided).
- Wire the sensor according to the wiring diagram; follow all applicable national and local electrical codes.
- Attach the sensor to the adapter plate by inserting the pins on the adapter plate into the keyholes on the back of the sensor. Rotate the sensor clockwise until it locks in place.
Figure 8: Wiring Diagram
This diagram illustrates the wiring connections for the occupancy sensor. It shows Class 1 connections: Hot (Black) to Black wire, Neutral (White) to White wire, and Load (Red) to Red wire, connecting to a Power Pack (SLSPP1277). It also shows Class 2 connections: Black, Blue, and Red wires for an optional additional sensor. The diagram notes the isolated relay contact rating is 1A @ 24 Vdc Resistive.OPERATING THE SENSOR
- Turn on the circuit breaker and any wall switches that may be supplying power to the sensor's power pack.
- Whenever motion is detected, the LED(s) on the sensor housing will flash on for approximately 0.5 seconds, and the lights will turn or remain on. NOTE: When first installed, the sensor may have to warm up for a few minutes before it is fully operational.
- Set the Time Delay to the Test setting of 15 seconds.
- Vacate the room until the lights turn off.
- Re-enter the room. Lights should turn on immediately. If lights do not turn on immediately, verify correct sensor wiring.
- Once the sensor is operational, adjust the settings.
ADJUSTING THE SENSOR
Follow the guidelines and refer to the diagrams below to properly adjust the sensor or switches lenses for proper operation.
Accessing the Sensitivity Adjustment Compartment
The adjustment panel is located on the front of the sensor housing. To access the adjustment controls, gently pry off the cover with a small, flathead screwdriver.
Figure 9: Adjustment Panel
This diagram shows the front of the sensor with the adjustment panel cover removed. The panel components are labeled: A. Sensitivity Adjustment, B. Mode Switch, C. Photocell Adjustment, and D. DIP switches.Modes and Sensitivity
Mode:
Determines when lights are turned on or will remain on.
Table 5: Sensitivity Modes
| Mode | Description |
|---|---|
| A* | Automatic mode. Normal, default setting. Lights will turn on or remain on only when the sensor detects motion. |
| M* | Manual override ON mode. Lights are always on. |
*A=Automatic/M=Manual
Sensitivity:
Determines the amount of movement required to trigger the sensor and the distance from which movement can be detected.
Rotate the sensitivity dial to enter a value (Clockwise = increase, Counterclockwise = decrease). The default sensitivity setting is approximately 50%.
Sensitivity is adjustable, from 10% to 100% of maximum sensitivity to increase or decrease the distance and movement required to trigger the sensor.
NOTE: Consider the characteristics of the room when adjusting the sensitivity of the Ultrasonic and Dual Technology sensors. Hard surfaces (concrete, tile, glass) are reflective and will create a higher sensitivity for ultrasonic detection.
NOTE: Soft surfaces (carpet, drapes, acoustical tile) will absorb some of the ultra sonic energy and reduce the unit's sensitivity. Building additions, such as cubicles and walls, may also require a higher sensitivity setting.
Photocell:
Sets the level above which ambient light will not trigger the sensor. The ambient light level can be set from 0.5-250 foot-candles. Turn the dial to the desired setting: from 0.5 foot-candles (fully counterclockwise) to 250 foot-candles (fully clockwise). The default setting is 250 foot-candles. This setting also disables the photocell, i.e., ambient light will not inhibit sensor operation.
TIME DELAY SETTINGS
Time Delay: A set of four DIP switches determines how long lights will stay on after motion is no longer detected. Settings range from 15 seconds to 30 minutes. The default setting is 18 minutes. The possible settings are shown in the "Time Delay Settings" table.
NOTE: The sensor employs self adjustment technology which senses occupancy patterns and continually adjusts the time delay to an optimal setting.
