TROUBLESHOOTING NOTES
If you experience problems with the 831 Receiver, try some of
the suggestions listed below before calling the Factory
Technicians.
R ECEIVER APPEARS DEAD ; THERE IS NO RESPONSE
WHEN TRANSMITTER BUTTONS ARE PUSHED .
Check the power connections to the receiver.
There must be at least 20 VAC at the receiver power
connections. (If a 24V system).
Review the code switch settings.
Any mismatch will prevent the receiver from working.
Try a different code switch setting.
Check the antenna installation.
Wait one minute for the receiver to “warm-up”.
Check battery in transmitter.
R ECEIVER “ CLICKS ” WHEN ANY TRANSMITTER
BUTTON IS PUSHED , BUT NOTHING ELSE HAPPENS .
Check the wire & connections in the STOP circuit. Refer
to Figure 3.
Check the OPEN & CLOSE connections.
The wire gage may be too small for the number of wall
stations used.
Check the power to the door operator.
Check the door operator’s control voltage.
S HORT DISTANCE OR INTERMITTENT OPERATION .
Relocate the antenna with a coaxial cable.
Metal objects too close to receiver, move to a better
location.
External interference (such as radio towers).
Change to a different frequency.
Stuck transmitter in building.
Change code switches from factory settings.
Check battery in transmitter.
O NE RECEIVER WORKS BUT THE OTHER IS DEAD .
Relocate the antennas.
Receivers too close together (cross-talking); move to
different locations.
Check code switch settings.
S OME THINGS TO REMEMBER :
Range is dependent on the installation, type of building,
type of door and the location of the transmitter. When
these conditions change so will the distance.
Any transmitter can interfere with operation. These
include cell phones, cordless phones, wireless systems and
CB and mobile transmitters. Other sources of interference
include computer equipment, industrial equipment,
electric motors, fluorescent lights, etc. The list is endless.
Do not lengthen or shorten the receiver antenna. It is set
to an optimal length based on the frequency of operation.
If the antenna is blocked or shielded (such as a car
traveling through a tunnel) the distance will decrease.
Always change the Factory set codes.

831 Commercial Receivers are designed to work with most commercial door operators. The 831 is connected to the commercial
operator in the same manner as a 3-button station and provides open, close and stop functions via radio control. The receiver
may be powered from the operator’s 24 VAC transformer or from a 115 VAC circuit. There is ample room in the 831 control
box to make the proper connections. The antenna is removable and may be moved (using coaxial cable) to a new location for
better RF reception.
