Installation Instructions
GARAGE DOOR
RADIO CONTROLS
MODEL 1099 RECEIVERS
WARNING:
•
Disconnect power before any installation or repair.
•
Wear safety glasses.
Your Multi-Code Radio Controls are designed specifically 
for the remote control of industrial door or ga te op ene rs 
and to give years of dependable service without 
adjustment.
Before you continue to read these instructions, note that 
there are 3 versions of the model 1099 receiver. The model 
1099-20 uses a 115-24 volt transformer. The model 
1099-40 comes with 4 wire connections for use with 
12VDC systems. The model 1099-30 comes with 4 wire 
connections for use with 24VAC systems. In addition, if 
you should choose to cut the transformer away from the 
1099-20, this modified product MUST ALSO BE WIRED 
TO 24VAC ONLY.
SELECTING A CODE
The code is determined by the positions of the 10 small 
switches numbered 1 through 10 located on the receiver 
board. To gain access to the switch, remove the top section 
of the case. Any combination of ON (CLOSED) or OFF 
(OPEN) positions can be selected by using a small 
screwdriver or ball point pen (see figure 1). We strongly 
urge that you avoid the following code schemes: ALL ON, 
ALL OFF, 2, 4, 6, 8, 10, on or 1, 3, 5, 7, 9, on. These codes 
are frequently used by other manufacturers, and create the 
possibility of false operation, and may be less secure than 
other code schemes.
Be certain to check that the code is functional before 
completing the installation.

INSTALLATION
The receiver comes equipped with a BNC receptacle and 
an antenna with a BNC plug. The antenna can be plugged 
directly into the receptacle, or it can be moved away from 
a metal structure, or to an outside location for better
receiver performance by using a coaxial kit available from 
your dealer.
Begin your installation of the 1099 by correctly wiring the 
receiver to the devices you will be using. WE URGE YOU
TO BECOME FAMILIAR WITH THE INSTRUCTIONS THAT THE MANUFACTURER OF YOUR 
EQUIPMENT HAS PROVIDED. SINCE, IN 
MANY CASES, THESE INSTRUCTIONS WILL DETERMINE THE WAY IN WHICH THE 1099 RECEIVER 
WILL BE INSTALLED.
The receiver should be mounted near the opener power 
head and can be installed in any position by using screws 
and the two slots in the cover flanges. Select a location and 
position that permits access to the terminals and space for 
the antenna as clear of metal structures as possible and 
preferably in a vertical position.
IF YOU HAVE THE MODEL 1099-20: Plug the transformer into a convenient 115 volt outlet. Connect the 
remaining gray wires as specified by the manufacturer of 
your operator. If such instructions do not exist, wire the 
two gray wires in parallel with the pushbutton terminals. If 
the operator has a three wire terminal, the proper terminals 
will usually be marked “1” and “2” or “24V” and 
“RELAY” (see figure 2).

IF YOU HAVE THE MODEL 1099-30: Wire the red and

remaining gray wires as specified by the manufacturer of 
your operator. If such instructions do not exist, wire the 
two gray wires in parallel with the pushbutton terminals. If 
the operator has a three wire terminal, the proper terminals 
will usually be marked “1” and “2” or “24V” and 
“RELAY” (see figure 3).

black wire will go to the negative terminal or ground 
terminal of the operator. Connect the two gray wires as 
specified by the manufacturer of your operator. If such 
instructions do not exist, wire the two gray wires in 
parallel with the pushbutton terminals (see figure 4).

At this point you should mount your 1099 receiver to its 
permanent installation, if you have not already done so.
ANTENNA INSTALLATION
After you have mounted your receiver, test it with the 
enclosed antenna for range, noting the coverage that you 
get from all desired operating locations. If greater range or 
coverage pattern is necessary, you may need the 1066 
Coaxial Wiring Kit, which is available from your dealer. 
Note that the 1099 external antenna coupling used a TYPE 
BNC antenna fitting. If necessary, you may use a TYPE 
BNC to TYPE F adapter, allowing you to use fittings found 
where television antennas are sold, along with 75 ohm 
antenna wire. It is not advisable to use lengths greater than 
20 feet, as this may affect range or tuning.
ADDITIONAL INSTALLATION INFORMATION
Linear Corporation has taken every possible precaution to 
make the 1099 receiver as reliable as possible. We think 
the following notes should be observed:
1. Be sure the unit is sealed from moisture, and, if at all 
possible, keep it away from direct moisture.
2. In those installations where vibration may be a factor, 
be sure to use a fastening compound, such as LOCTITE 
(TM) on the mounting screws to insure reliable 
mounting.
3. If this, or any other equipment is being used in a 
safety-related device, be sure to test the entire system at 
the time of installation, and at frequent intervals, to 
determine that it is working properly.
OPERATIONAL CHECK
To check operation, move back a reasonable distance 
(about 50 feet) and press the transmitter button. Operation 
should be reliable at this distance but environment and 
location of both the transmitter and receiver will affect the 
range. If the transmitter is stowed well out of sight, it may
be necessary to remove it from its mounting and hold near 
the windshield. Try different locations and positions. If 
operation is still unsatisfactory, check the following:
1. The antenna must be connected to the receiver for 
normal use.
2. If the opener fails to operate, check to see that 115 VAC 
power is present. Check circuit breakers or for a system 
power failure.
3. If the opener operates by pressing the wall button, but 
not when the transmitter button is pressed, the radio 
controls are probably at fault. Check to m ake sure
both transmitter and receiver code switches are set 
to the exact same code since a difference of just one 
switch will prevent operation. Check transmitter bat-
tery, location of the transmitter and receiver installation.
4. Try mounting the antenna at a more favorable remote 
location by utilizing the coaxial kit.
If, after performing the above op erational check, it is 
necessary to return the radio controls, return both the 
transmitter and receiver to your dealer for repair or 
replacement or they may be returned, postage prepaid, 
directly to Linear Corporation.
