Almost all types of access control devices may be connected to models BG770 and BG790. More
than one device may be connected in parallel. All devices connected according to the instructions
below will open the gate and reverse the gate if it is closing.
MOUNTING LOCATION
Mount or install the access control device within sight of the gate and according to the instructions
supplied with the device. Some devices require their own power supply. Do not use the 24 volt
power in the gate to supply other devices. Use either direct line voltage (115V or 230V) or
other external power source as required by the particular device.
NOTE: Most access control devices have an isolated, normally open output contact to
connect to the gate. If yours does not, or if you are unsure of or unfamiliar with these
terms, consult the supplier of the device or a qualified gate installer.
CONTROL CONNECTION
TURN OFF POWER and connect the two output terminals (or wires) of the access control device
to the terminals #1 and #3 on the control wiring terminal strip. Use a wiring method that will
provide permanent, durable, and weatherproof connection between the gate and the access
device.
