4. Connect a three conductor, color coded cable onto the receiver's terminals (the connector clips
provided with the receiver are not used in this type of installation).
5. Loosen the terminal screws on the operator and insert the other end of the cable under the
screw heads. The wire attached to the right terminal on the receiver should be connected to
the "24 VOLT" terminal on the operator, the wire attached to the center terminal on the receiver
should be connected to the "RELAY” terminal on the operator and the wire attached to the left
terminal on the receiver should be connected to the operator terminal marked "COMMON" or
"RADIO POWER".
6. If you have a wall button, wire it to the "24 VOLT" and "RELAY" terminals.
7. Tighten the terminal screws on the operator until the wires are all held firmly and make sure the
antenna (on the bottom of the receiver) is in a vertical position as far from any metal as
possible. Reconnect the power to the garage door operator.
CONNECTING A REMOTELY MOUNTED RECEIVER TO A TWO-TERMINAL OPERATOR
NOTE: The receiver has three input/output contacts at TB1 which are labeled on both the P.C.
board and the ID tag on the back of the receiver baseplate. TB1-1 (24VAC/COM) and TB1-3
(RADIO POWER) are used to power the receiver. TB1-1 (24VAC.COM) and TB1-2 (RELAY)
provide a normally-open relay contact to activate the garage door operator.
1. Disconnect the power to the garage door operator.
2. Disconnect any existing receivers from the operator.
3. Install 24VAC 250ma transformer. DO NOT PLUG THE TRANSFORMET INTO A 110VAC
OUTLET YET.
4. Select a location for the receiver. The receiver will need to be placed so the antenna
points down and needs to be as far away from any metal as possible. Mount the receiver
using the tabs located on the top of the unit.
5. Connect one 24VAC transformer wire to TB1-1 (24VAC/COM) on the receiver. Connect the
other 24VAC transformer wire to TB1-3 (RADIO POWER) on the receiver.
6. Connect TB1-2 (RELAY) of the receiver to the “RELAY” terminal on the operator
7. Connect TB1-1 (24VAC/COM) of the receiver to the “COMMON” terminal on the operator.
8. Optional: if you have a wall button, connect it to TB1-1 (24VAC/COM) and TB1-2 (RELAY) on
the receiver.
9. Connect power to the power transformer.
10. Reconnect power to the garage door operator.
IMPORTANT NOTE:
Some operators have an internal receiver that must be disconnected and unpowered before this
garage door receiver is installed. If there is no external receiver seen, but there is an antenna
protruding from the operator and/or you are currently using another transmitter, you more than
likely have an internal receiver. For instructions concerning proper disconnecting procedures to
unpower the receiver or if you are unsure whether or not your operator has an internal receiver,
call the operator's manufacturer.
