2- Install Transmitter and Test
2-1. Open and unpack the batteries, Transmitter
and Receiver units.
2-2. Loosen Top Lid Screws on the Transmitter and remove lid.
Remove the Receiver Top Lid by pressing one side of the
snap lock base inward while lifting lid.
2-3. Set the 9 Pole, 3 Position Coding Switch on the Receiver to
match the Transmitter’s 9 Pole, 3 Position Coding Switch. Any
switch position will work as long as the Transmitter coding switch
and the Receiver coding switch are exactly matched (must be
different from other nearby transmitters of the same type).
2-4. Place the two (2) AA batteries in their holders on the Transmitter
in the proper direction, paying attention to the (+) and (-) ends.
Momentarily press the Test Button on the Transmitter.
The Green Tx LED Indicator should light for 3 seconds.
To test the Alarm on the MWTA12 Model, press and hold the
Test Button. The Alarm should sound in approximately ten (10)
seconds. Release the Test Button.
2-5. Route the wires from the safety edge through
the Transmitter’s Strain Relief Cable Fitting for
approximately four inches.

2-6. Strip the insulation from the two wires back ¼”. Pull the
Terminal Block off the Transmitter’s PCB. Place the safety
edge wires in the Terminal Block and tighten with screwdriver.
Re-seat the Terminal Block on the PCB (see Fig. 2-6).

3-1. Set the 9 Pole, 3 Position Coding Switch on the Receiver to
match the Transmitter’s 9 Pole, 3 Position Coding Switch. Any
switch position will work as long as the Transmitter coding switch
and the Receiver coding switch are exactly matched (must be
different from other nearby transmitters of the same type).
3-2. Mount Receiver inside the operator control box so that the wires
from the receiver will reach the terminal strip on the operator.
3-3. Wiring:
a. The red (+) and black (-) wires are your power leads. They
connect to your operator panel terminals that provide the
appropriate power (12-24 VAC/VDC). Black wire is common,
Red wire is (+) or AC power.
b. The green wire is your standard antenna wire. This must be
located outside of any metal enclosure to provide for good
signal reception. There is an F-Connector antenna fitting
included on the receiver in the event a remote antenna
placement is needed.
c. Receiver Connections: The white wire will go to your
operator’s low voltage common terminal. If your operator
requires a normally open (N.O.) contact, connect the
yellow wire to the operator’s safety edge input. If the
operator requires a normally closed (N.C.) contact,
connect the orange wire to the operator’s safety edge input.
