INSTALLATION

1. Choose a location for sensor:
• Ensure sensor is firmly mounted on a flat surface. Avoid vibrations.
• Objects such as fans, plants, flags, etc must not protrude into the
detection area.
• Make sure sensor has an unobstructed view. Obstruction can effect
performance of sensor.
• Mount sensor away from fluorescent or HID light sources.
Recommended Mounting Heights (Factory default is setting 4):
Setting 1 = 6.5' (2 m) - 8' (2.5 m)
Setting 2 = 8' (2.5 m) - 10' (3 m)
Setting 3 = 10' (3 m) - 13' (4 m)
Setting 4 = 13' (4 m) - 16.5' (5 m)
Setting 5 = 16.5' (5 m) - 19.5' (6 m)
Setting 6 = 19.5' (6 m) - 23' (7 m)
2. Remove the sensor from mounting bracket by loosening the hand-
screws.
3. Affix the self-adhesive mounting template to the wall or ceiling and
drill 3/16" or 5 mm holes in specified locations. Remove the template.
4. Route the cable through the opening in the mounting bracket and
ensure cable length is sufficient to accommodate desired inclination
angle.
5. Secure the mounting bracket to the wall or ceiling using screws.
6. Attach sensor to mounting bracket as shown. Tighten hand-screws to
secure.

• Follow ALL steps outlined in this manual in order for proper
installation of the product.
• Stop ALL traffic through the door BEFORE installing sensor.
• Ensure there is no vehicle or pedestrian traffic through the door
until sensor is installed and tested for compliance with ALL
applicable safety standards (e.g. UL 325).
• Verify proper installation of door equipment BEFORE installing
sensor.
• Shut off ALL power BEFORE attempting ANY wiring procedures.
• ALWAYS use wire terminals to terminate stranded wire ends.
• Check placement of wiring to ensure moving parts are NOT
impeded by wires.
• Make sure wiring is correct BEFORE applying power to the sensor
to avoid DAMAGE to equipment.
• Ensure door and header, including housing components, are
properly grounded to protective earth (PE).
• Ensure (e.g. by walk testing) that installation is in compliance with
ALL applicable standards (e.g. UL 325) after completion of
installation.
• If the sensor sustains damages (e.g falls), replace it with a new
sensor.
• If a satisfactory solution cannot be achieved after troubleshooting,
please contact tech support at 800-528-2806.
