(The Red Low Battery LED will only light when the batteries fall below 2.4v.)

2-10. Mount the Transmitter to the door or gate using #6 - 20 x 3/4” self-drilling screws.The mounting holes are

located under the Top Lid Screws. Mount the transmitter with the wire strain relief facing down or to the side.

3-1. Remove lid of the Receiver Unit.
3-2. Set the Group (red) and Address (blue) switches to

match the transmitter settings.

3-3. Mount the receiver close to the operator and in-the-line-of-sight

of the transmitter using the mounting holes, as shown.

3-4. *Connect the receiver’s PE (Photo-Eye) output to the operator’s

PE input terminals using Green and White wires.
(Operator terminal label naming may differ. Contact factory for

support).
3-5. Connect the Black and Red wires to a 12 or 24V ac/dc source.
3-6. Attach the antenna to the receiver RF board.
3-7. Preliminary Test :

Confirm that the Transmitter and Receiver are powered ON.

Activate the Safety Edge (or monitored device).

The Address Valid Yellow LED on the Receiver should

flash momentarily.

If the Address Valid LED does not flash, check that the

Group and Address switches match the transmitter

settings. Confirm that the Photo-Eye and Safety Edge

LEDs are lit while the safety edge is held active.

Note that the Photo-Eye and Safety Edge LEDs

go OFF when the Edge is released.
3-8. Replace the Receiver Lid taking care to slip

the Antenna through the lids’ grommet.

*Certain installations may require an alternative wiring

scheme. Please consult factory for assistance.
