1. PRODUCT DESCRIPTION

Linear’s Xtended Range FM transmitters and receivers are designed for use in various
wireless remote control applications. When triggered with an external switch, the Model XT-1
transmitter will send a 10 watt, 27.255 MHz, digital encoded, FSK modulated, signal to its
companion receiver. The receiver will verify the digital code, activate its output, and trigger
the remote device.

The XT-1 transmitter has full supervision capabilities. If the “status” option is selected, the
XT-1 sends hourly status signals to its receiver. 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, causing
a momentary receiver output each time the transmitter is activated. Either a N/O or N/C input
(jumper selectable) can trigger the transmitter.

Power for the XT-1 transmitter can come from an external regulated 12 VDC, 2-Amp power
supply (Linear Model T-1224DC) or from a 12-volt battery. A 3-amp fuse protects the unit
from reverse power polarity. The XT-1 draws about 15 μA standby, and about two amps
during transmissions. If the power supply voltage drops below 10.5 volts, a low battery
message will be included with any signal transmitted, causing the receiver’s low battery
output to activate.

Two antennas (sold separately) are available for the XT-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 XT-1 is required. A
common 9-foot 1/4 wave CB whip antenna can also be used with the XT-1 for maximum
range.

Two 8-position switches set the unit’s system code. This code must be matched in the XT-1’s
receiver. There are 65,536 different system codes possible. The 6-position option switch
selects the transmitter’s channel, receiver’s bank (for XR-16 receiver only), and options for
status and auto-restore transmissions.

The transmitter is housed in a rugged weather-resistant metal enclosure with a sturdy
SO-239 antenna connector and a water-tight wiring strain relief bushing. During
transmissions, the red operation indicator (visible through a window on the case) lights. If
the XT-1’s input voltage is low, the indicator will blink during transmissions.

3. COMPONENT LOCATIONS 4. INSTALLATION TIPS 5. MOUNT TRANSMITTER 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 should be communicated to the ultimate users.
