Radio Controls; Additional Access Control Equipment; External Interlock Switch; Test The System - Chamberlain GH Owner's Manual

RADIO CONTROLS

On all models with type B2 control wiring, a terminal bracket
marked R1 R2 R3 is located on the outside of the electrical
enclosure. All standard radio control receivers (single channel
residential type) may be mounted to this bracket. The operator
will then open a fully closed door, close a fully open door, and
reverse a closing door from the radio transmitter. However, for
complete door control from a transmitter, a commercial three-
channel radio set (with connections for OPEN/CLOSE/STOP) is
recommended.

ADDITIONAL ACCESS CONTROL EQUIPMENT

Locate any additional access control equipment as desired (but
so that the door will be in clear sight of the person operating the
equipment), and connect to the terminal block in the electrical
enclosure as shown on the FIELD WIRING CONNECTIONS
diagram. Any control with a normally (N.O.) isolated output
contact may be connected in parallel with the OPEN button. More
than one device may be connected in this manner. Use 16 gauge
wire or larger for all controls. NOTE: Do not use the control
circuit transformer (24Vac) in the operator to power any access
control equipment other than a standard residential type radio
receiver.
Turn on power. Test all controls and safety devices to make sure
they are working properly. It will be necessary to refer back to
page 6 for fine adjustment of the limit switches.
IMPORTANT NOTES:
• Do not leave operator power on unless all safety and
entrapment protection devices have been tested and are
working properly.
• Be sure you have read and understand all Safety Instructions
included in this manual.
• Be sure the owner or person(s) responsible for operation of the
door have read and understand the Safety Instructions, know
how to electrically operate the door in a safe manner, and know
how to use the manual disconnect operation of the door
operating system.

WARNING WARNING
DO NOT use radio controls with your operator unless you
CAUTION
have installed some type of entrapment protection device. The
use of radio controls presents potential hazards due to the
user's ability to open or close the door when out of sight of
the door. In addition, if a single channel control is used, the
user will not be able to stop the door from the remote control.

EXTERNAL INTERLOCK SWITCH

The operator has a terminal connection for an external interlock
switch. This switch must be a normally closed (N.C.) two-wire
device with a contact rating of at least 3 amps at 24 Vac. When
such a switch is connected as shown on the FIELD WIRING
CONNECTIONS diagram, the control circuit will be disabled when
AVERTISSEMENT
the switch is actuated, thereby preventing electrical operation of
the door from the control devices.
ATTENTION
WARNING WARNING
DO NOT place hands or tools in or near the operator when the
CAUTION
power is on or when testing control or safety devices.
ALWAYS disconnect power BEFORE servicing or adjusting the
operator.
