Tools Required:

1. 1/8” Flat blade screwdriver

2. 1/4” Flat blade screwdriver
Recommended:

VOM for test purposes
Mounting screws as required
Terminated sensing edge sold separately

2- Install Transmitter and Test

2-1. Open and unpack the antenna, batteries, transmitter

and receiver units.
2-2. Loosen screws from the top cover and remove the lid.
2-3. Remove the Transmitter PCB by pulling upward on one

of the silicone caps.

2-4. Route the wires from the monitored edge through

the strain relief cable fitting for approximately four inches.
Strip the insulation from the two wires back ¼” and secure

the wires in the terminal strip position marked SE.

2-4A. A Knockout (K.O.) switch may be wired to the Tx

terminal strip marked KO-1 and KO-2. Either normally

open or normally closed switches may be used.
2-5. Place the two AA Lithium batteries in their holders in

the proper direction, paying attention to the (+) and (-) ends.

2-6. Tuck the wires connected to the SE terminal block neatly

between the batteries and pull the excess wire back
through the strain relief.

6-A. Re-seat the PCB and securely tighten the cable fitting.

2-7. Set the Termination Type switch to either 10K resistive

or 9.1v Diode. (see Appendix) This selection must match
the Termination type in the Monitored Device.

2-8. Address Switches

Set the Group(red) and Address (blue) switches to
the desired position. (Note the settings for reference when

setting up the Receiver)

If the Group switch is set to 0, the address switch may be
set to any position between 0 and F.
If the Group switch is set to 1, the Address switch may be
set to any position between 0 and B.

The remaining positions, C, D, E, and F are reserved for

factory test.

2-9. Momentarily press the TEST button to load the address and group data. The Green Tx Data led should flash.

The Red Low Battery led will only light when the batteries fall below 2.4v.

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

the Top Lid. Mount the transmitter with the wire outlet facing down or to the side.

-11. Replace the cover on the Transmitter and tighten the screws taking care to align the lid.

3- Install Receiver and Test

NTENNA

3-1. Loosen screws from the top lid of the Receiver Unit and

remove the lid.

3-2. Set the Group (red) and Address (blue) switches to

match the transmitter settings. (see Apendix)

3-3. Set the termination selection jumper to either 10k

resistive or 9.1v Diode (to suit the Operator).

3-4. Mount the receiver close to the operator and in the line

of sight of the transmitter using the pre-drilled mounting
holes as shown.

3-5. Connect the receiver’s PE (Photo Eye) output to the operator’s

photoeye input terminals using Green and White wires.
(operator terminal label naming may differ. Contact factory for
support). (See Pic.#1)

3-6. Connect 12/24V into 12/24VAC/DC source using Black and

Red wires. (See Pic. #2)
3-7. Connect the antenna to the receiver RF board.
3-8. 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

flashes 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.
3-9. Replace the Receiver Lid taking

care to slip the Antenna

thru the top lid membrane.
