INSTALLATION INSTRUCTIONS
Description:
The passive infrared sensors work by detecting the difference between heat emitted from the human body in motion and the background space.
The sensor switch can turn a load ON and hold it as long as the sensor detects occupancy. After no motion is detected for the set time delay, the
load turns OFF automatically. The sensor switch has one relay (equal to single pole switch), it also includes Auto Set and Walk Through features.
Coverage Area:
The coverage range of the sensor switch is specified and illustrated in Figure 1. Large objects and some transparent barriers like glass windows
will obstruct the sensor’s view and prevent detection, causing the light to turn off even though someone is still in the detection area.
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 sensor’s field-of-view.
INSTALLATION
1. Connect lead wires as shown in WIRING DIAGRAM (see Figure 2): Black lead to Line (Hot), Red lead to Load wire, Green lead to Ground.
2. Gently position wires in wall box, attach sensor switch to the box.
3. Mount device “TOP” up.
4. Restore power at circuit breaker or fuse, wait
three
minutes.
5. Remove the small cover plate. (Illustrated as Figure 3.)
6. Locate the adjustment knobs on the control panel to perform test and adjustment. (Illustrated as Figure 4.)
7. Replace the small cover plate after testing and adjustment.
8. Attach the wallplate.
NOTE: If twist on wire connector is provided, use to join one supply conductor with one 16 AWG device control lead.
ADJUSTMENT
Band Switch
Time Delay Knob
Default position: 15 Seconds (Test mode)
Adjustable: from 15 Seconds to 30 Minutes (clockwise)
Sensor Sensitivity Range Knob
Default position: Center at 65%
Adjustable: 30% (Position 1) to 100% (Position 4)
Note: Turn clockwise for larger rooms. Turn counter clockwise to avoid false alerts in smaller rooms or near doorway or heat
source.
Back to factory default (daylight):
Set the Band Switch to VAC, press and hold the Manual ON/OFF Button for 6 seconds until the Load turns on, continue
holding the button for another 5 seconds until the Load turns off, then release the button and set the Band switch to OCC or
AUTO mode, it confirms that the sensor switch has reset to factory default.
OPERATION
The Sensor Switch is programmed independently for any Mode (AUTO, OCC or VAC) as referred to the Band Switch position
under the control panel cover. Some might call the Vacancy mode as “Manual ON Occupancy Mode”.
Manual On/Off Button:
By pushing the Control Panel Cover, the load can be turned ON/OFF under either OCC or VAC mode. (Illustrated as Figure 5)
There is a 5 seconds re-trigger delay between ON and OFF.
Turning On the load under Occupancy Mode:
Load will turn ON once occupancy is detected.
Turning On the load under Vacancy Mode:
Manual ON/OFF Button has to be pushed to turn On the Load.
Automatic Turning Off the load:
Under any Mode, the sensor keeps the Load ON until no motion is detected and the set time delay, Loads will turn Off automatically.
Manual Turning Off the Load:
By pushing the Manual ON/OFF Button, the Load can be turned OFF under any mode. Under AUTO/OCC Mode, the Load cannot automatically
turn On 5 mins after the last motion is detected.
Auto Set Occupancy Mode:
Automatically set the time delay between 7 to 30 minutes based on occupancy patterns. Auto set behavior starts after the time delay knob is turned away
from Test Mode, also including the walk-through mode.
Walk-Through Mode:
During walk-through mode, the Load automatically turns ON and then turns OFF 2.5 minutes later, after an occupancy moment of 30 seconds. If motion
is detected within the first 30 seconds and in the coming 2.5 minutes, Auto Set Occupancy Mode applies.
