DESCRIPTION:
The IOS-CMP-DT-LV 360° Dual Technology Low Voltage Occupancy Sensors control the load based on
occupancy and ambient light levels. It combines passive infrared (PIR) and ultrasonic technologies to
help avoid false triggering while increasing presence detection. Selectable modes allow the sensor to
turn load ON and hold it ON as long as either or both technologies detect occupancy. If no movement is
detected for a user-specified time of 5 seconds to 30 minutes, the load is turned OFF. The occupancy
sensor provides a 360° coverage pattern, up to 1600 ft

MOUNTING THE SENSOR
NOTE: A junction box and screwdriver are needed to complete this procedure.
See Figure 4 for reference.
1. Make sure power is turned off at the main disconnect.
2. Look for small opening on periphery of cover. With the help of a flathead screwdriver, snap off front
cover. Next, remove mounting adaptor by opening tabs A & B as shown in Figure 4.
3. Attach mounting adaptor to junction box.
4. Observe these guidelines when mounting the sensor:
• The occupancy coverage area may be more or less than the sensing distances shown in Figure 1
due to potential coverage area obstacles, such as furniture or partitions.
• Place the sensor at least 4 to 6 feet (1,2 to 1,8m) away from air supply ducts to prevent false
activations.
• If you mount the sensor outside of 8 to 10 feet (2,4 to 3m) from the floor, it affects the coverage
pattern. Decreasing the mounting height decreases the sensor range and increases the sensitivity
to smaller motions. Mounting the sensor at heights more than 12 to 14 feet (3,7 to 4,3m) reduces
sensitivity.
• For coverage of large areas with multiple sensors, an overlap of 10 to 20% is recommended as
shown in Figure 2.
• Avoid placing the sensor directly in line with an open door through which it has a clear view out.
This may cause the sensor to detect people walking by the door.
5. Punch knockout on the junction box and insert the IOS-PP24 power pack nipple into the knockout.
6. Pull the low voltage wires from the power pack into the junction box, through the conduit knockout.
7. Connect the low voltage wires from the power pack to the appropriate wire on the occupancy
sensor. See table below for wire designations. Refer to Figure 3.
Wire from power pack To Terminal on Occupancy Sensor
Red wire (+24 VDC) +24 VDC terminal
Black wire (Common) Common terminal
Blue wire Control Out terminal
8. To connect multiple sensors (up to 6) to power pack, run the blue control out wire from the sensor
to the blue wire of the power pack.
9. Align and snap sensor onto mounting adaptor.
10. After setting adjustment, snap cover back onto sensor.

WARNING
Risk of Fire or Electric Shock
• Disconnect power at the circuit breaker(s) or fuses before installing or servicing.
• Installation and/or wiring must be in accordance with national and local electrical code
requirements.
• Use COPPER conductors ONLY.
• Indoor dry location use only.
• Do not exceed electrical ratings.
