Precautions
1. SHUT OFF power to header before attempting any wiring procedures.
2. MAINTAIN a clean and safe environment when working in public areas.
3. Constantly BE AWARE of pedestrian traffic around the door area.
4. Always STOP pedestrian traffic through the doorway when performing tests that may
result in unexpected reactions by the door.
5. OBSERVE proper protocols for circuit board handling to protect the unit from
electrostatic discharge.
6. Before handling any board, ENSURE dissipation of any bodily charge.
7. CHECK placement of all wiring before powering to ensure that moving door parts do
not catch wires and cause damage to equipment.
8. ENSURE compliance with all applicable safety standards (i.e., ANSI A156.10/A156.19)
upon completion of installation.

9. DO NOT ATTEMPT any repair of the sensor.
10. Unauthorized disassembly or repair:
•May jeopardize personal safety and may cause exposure to the risk of electrical
shock.
•Will void the product warranty.
Installation / Wiring / Setup
Installation
1. MOUNT the WSS using the included mounting ring or in a standard plastic or
metal electrical gang box, as applicable, and depending on the type of door
installation.
NOTE 1: The weather resistant foam is used as a protective barrier against
the elements.
NOTE 2: The plastic adapter ring enables the double gang face plate to
attach to various plastic and metal gang boxes.
NOTE 3: If using a metal electrical box, do not allow contact between the sensor
and the box to prevent shorting the device.
2. ENSURE placement of the device so that motion from the door or other types of
movement do not interfere with the detection zone.
Wiring
1. WIRE the four-conductor cable as shown below.

3 500-23710_1
NOTE: Use either green (N.O.) or yellow (N.C.) wire, not both. Refer to the
door control manual to determine which must be used.
Setup
NOTE: Four adjustments can be made to the sensor.
1. Sensitivity potentiometer: adjust detection field
from 4 to 24 inches (rotate clockwise to
increase)
Factory default: 4 inches (fully CCW)
2. Hold time potentiometer: adjust relay hold time
from 0.5 to 30 seconds (rotate clockwise to
increase)
Factory default: 0.5 sec (fully CCW)
3. Output Mode switch: determines Toggle mode
or Timer mode
•Toggle (switch up) = detection activates
the relay and the relay holds until a
second detection deactivates the relay
(recommended for switch applications)
•Timer (switch down, factory default) = detection activates the relay for
0.5 to 30 seconds; relay will hold as long as detection occurs
4. LED mode switch: determines if LED illuminates when in detection or when
not in detection
•switch up (factory default) = LED on when sensor is NOT in detection,
LED off when in detection
•switch down = LED on when sensor is in detection, LED off when not
in detection
Troubleshooting
PROBLEM: Door does not open when swiping hand in front of sensor.
CAUSE/ACTION:1. Bad or no power supply. . CHECK power supply. If LED switches on
or flashes, power connections are OK.
2. Detection range is too small. ADJUST the detection range. REMOVE
any metal plates in front of sensor.
3. Wrong connection. CHECK wiring and relay connection.
PROBLEM: Door remains permanently open.
CAUSE/ACTION:1. Environmental conditions are influencing the sensor. REMOVE any
moving objects close to the sensor.

4 500-23710_1
2. Wrong connection/Output mode.CHECK wiring and relay connection
and switch output mode to Timer.
PROBLEM: The door remains open after detection/activation.
CAUSE/ACTION:1. Wrong output mode. SWITCH the output mode to Timer Mode.
2. Wrong connection. CHECK wiring and relay connection.
