11. Accessories
11.1 Power BackUp for SC-325 Controller (Ordered Separately)
When the SC-325 controller is used with the 115 VAC Power BackUp controller, the RS-500
door can be operated several cycles in the event of a power outage. Refer to
Section 12.7
for
connections to the Power BackUp.
11.2 Remote Transmitter and Receiver (Ordered Separately)
The Remote Receiver may be powered from the SC-325 or SC-650 PCB 154 “DC Power”
connection (12 VDC). The Receiver SW1 voltage selection switch must be set to 12v and SW2
relay output must be set to continuous (CONT). The Remote Receiver is normally wired to the
PCB 154 Sequential Timed connection. The receiver comes standard with a “F” connector and a
½ wave wire antenna. If signal conditions require the use of an external coax antenna to eliminate
signal blockage due to obstructions, dead spots, etc., use RG59 coax to extend the antenna to the
remote location. The ½ wave wire antenna may be left on the receiver. The receiver and
transmitter 9-pole, 3 position coding switches can be set to any switch position
as long as the
receiver coding switch and transmitter coding switch are exactly matched
. Refer to
Section 12.11
for connections to the Remote Receiver.
