DESCRIPTION:
The IOS-DOV-DT series Dual Technology Occupancy Sensors In-Wall sensor switch controls
a load based on occupancy, vacancy 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 15 seconds to 30 minutes, the load is turned OFF. The sensor provides a 180° coverage
pattern, up to 1200 ft

INSTALLATION
1. Make sure power is turned off at main disconnect.
2. Remove existing single pole switch or dimmer installation, if applicable.
3. Remove 3/4” (1.9 cm) of insulation from each circuit conductor. Make sure the ends of
wires are straight.
4. Connect lead wires as shown in WIRING DIAGRAM (see Figure 2): Black lead to Line
(Hot), Red lead to Load wire, White lead to Neutral wire, Green lead to Ground.
5. Gently position wires in wall box, attach sensor switch to the box.
6. Mount device “TOP” up.
7. Restore power at circuit breaker or fuse, wait one minute.
8. Remove the small cover plate by lifting from bottom edge (see Figure 3).
9. Locate the adjustment knobs on the control panel to perform tests and adjustments
(see Figure 4).
10. Replace the small cover plate after testing and adjusting.
11. Attach the wall plate.

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.
LOCATION/MOUNTING
Since this device responds to temperature changes, care should be taken when mounting
the device. DO NOT mount directly above a heat source, in a location where hot or cold drafts
will blow directly on the sensor, or where unintended motion will be within the sensor’s
field-of-view.
SENSOR ADJUSTMENT
Remove the cover from the sensor.
NOTE: There is a 40 sec warm-up period when power is first applied to unit.
The sensors are factory preset to allow for quick installation in most applications. Follow
this procedure to verify the sensor coverage and customize the settings.
BAND SWITCH
Sensor has the ability to be set as an occupancy or vacancy sensor. The main difference is that when set to
vacancy mode the load will only turn ON with the push button.
