1. PRODUCT DESCRIPTION
Linear’s Xtended Range FM receivers and transmitters are designed for use in various
wireless remote control applications. When the Model XR-1 receiver detects a signal from
its companion transmitter, it will verify the digital code, activate its output, and trigger the
remote device connected to the receiver.
The XR-1 receiver has full supervision capabilities. If the “status” option is selected, the
receiver expects hourly status signals from its transmitter. If these signals cease, the receiver
will indicate trouble by activating its status output after four hours. Contact supervision allows
the receiver’s output to follow the transmitter’s input, staying activated as long as the
transmitter input is activated. Alternately, an “auto-restore” option can be selected in the
transmitter, causing a momentary receiver output each time the transmitter input is activated.
If the transmitter sends a low battery signal, the receiver’s low battery output will activate.
Power for the XR-1 receiver can come from an external regulated 12 VDC power supply
(Linear Model T-1224DC) or from a 12-volt battery. A diode protects the unit from reverse
power polarity. The XR-1 draws about 30 mA standby, and about 70 mA when the output is
active. The receiver output provides isolated N/O and N/C relay contacts capable of switching
a maximum of 1 Amp @ 32 VDC. The low battery and status outputs are solid state and are
capable of switching up to 50 mA @ 20 VDC to ground.
Two antennas (sold separately) are available for the XR-1. The Model ANT-1A is an 8-inch
“rubber duck” antenna for short range applications (less than 1 mile). The ANT-1A requires
a CON-180A (straight) connector to mate the antenna to the transmitter. For a right angle
antenna, use the CON-180A plus the CON-90A.The Model ANT-2 is a 3-foot whip antenna
for use in long range or difficult installations where more range from the XR-1 is required. A
common 9-foot 1/4 wave CB whip antenna can also be used with the XR-1 for maximum
range.
Two 8-position switches set the unit’s system code. This code must be matched in the XR-1’s
transmitter. There are 65,536 different system codes possible. The 4-position option switch
selects the receiver’s channel (to match the transmitters channel), and status supervision option.
The receiver is housed in a rugged weather-resistant metal enclosure with a sturdy SO-239
antenna connector and a water-tight wiring strain relief bushing. Two indicators are visible
through a window on the case. The green power indicator lights when the receiver has power.
During reception, the red RF indicator lights. Two internal test points are provided for signal
strength and audio monitoring.

3. COMPONENT LOCATIONS 4. INSTALLATION TIPS 5. MOUNT RECEIVER CASE
If using the ANT-1A antenna: For best range mount the XT/XR unit to a metal plate with a
minimum size of 12" x 12". The ANT-1A antenna should extend above the mounting plate
and be free of obstructions. If the ANT-1A antenna cannot be mounted in the open, consider
using an extension coaxial cable with PL-259 connectors to move the antenna’s location.
The XT/XR series of radios operate in the 27 MHz Citizens Band (CB) and may use any CB
antennas or CB antenna accessories. Antennas, PL-259 extension cables and other
adapters are available at Radio Shack® or other electronics stores.
