INSTALLATION INSTRUCTIONS
Model 2031, 3021, and 3028 2 Channel Receivers
WARNING:
• Disconnect power before any installation or repair.
• Wear safety glasses.
Congratulations! You have purchased a MULTI-CODE
RECEIVER, which we believe to be the finest product of
its kind on the market. If you take a moment to read the
enclosed instructions, we think that you will find installation of your receiver to be quite an easy matter, and will
assure reliable operation.
INSTALLATION
Your Receiver may be mounted in the operator head, if
space permits, or remotely, if this becomes necessary.
Note that all wires should be route d through the strain relief
fitting or rubber grommet of the cabinet, except for the
antenna lead.
Begin your installation by correctly wiring the receiver to
the devices you will be using.
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 RECEIVER WILL BE
INSTALLED.
Note that on the top half of your cabinet you will find a
terminal designation schematic. This schemat ic is reprodu ced
below for your reference (figure 1)

The two positions marked 24 VAC are used to attach your
power supply. If you find that your operator supplies only
110 VAC, then contact LINEAR CORPORATION for the
1092-01 power supply, and we will provide an adapter for
110 to 24 Volt use.
The next three positions, above the 24 VAC positions, provide channel 1 selection. Selection of Channel 1 on the
transmitter is made by setting th e number 10 DIP switch to
the open position. You must then choose to wire the first
channel to a NORMALLY OPEN or NORMALLY CLOSED circuit. To determine this, con sult the manuf acturer ’s ins tructions, as previously noted. Refer to your transmitter
instructions for coding instruc tions. Now att ach the second
wire from your device to common.
Above the channel 1 positions you will see the positions
which allow channel 2 to be wired. Channel two is wired in
the same manner as channel one, wi th the exception of the
transmitter code switch number 10 being placed in the
closed or on position.
You will note that the two channels on the receiver may be
used in any combination of NORMALLY OPEN or NORMALLY CLOSED devices.
At this point you should mount your receiver to its permanent installation, if you have not already done so. If you
have a 3021 receiver be sure to tightly secure the strain
relief fitting through which the wires are routed as this
provides a degree of water resistance. Should you desire
a watertight connection, use a single length of 16 to 22 gauge
jacketed cable.
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 ne cessary, you may choo se the MULTICODE 1066 Coaxial Wiring Kit, which is available from
LINEAR CORPORATION. Note that the external antenna
coupling uses a TYPE F antenna fitting. If necessary, you
may use TYPE F 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.
