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 digita l code, activate its output, and trigger the
remote device connected to the receiver.

RECEIVER

For Use With Linear’s
XR Series Xtended
Range Transmitters

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

Instructions

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.

IMPORTANT !!!

Linear radio controls provide a reliable communications link and fill an important need
in portable wireless signaling. However, there are some limitations which must be
observed.

1 WARNING: THIS PRODUCT IS NOT TO BE USED IN LIFE SAFETY APPLICATIONS. FCC Rules allow

unlicensed high-power transmissions at or near the operating frequency of this product which may
interfere with, or even disable, normal operation of this radio device.

1 For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 95

Radio Control devices. As such, they have limited transmitter power and therefore limited range.

1 A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals

that occur on or near their operating frequencies, regardless of code settings.

1 Changes or modifications to the device may void FCC compliance.
1 Infrequently used radio links should be tested regularly to protect against undetected interference or fault.
1 A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor or

dealer, and these facts sh ould be communicated to the ul timate users.
