Linear Model XR-1 Extended Range Receiver
Up to 10 miles of line-of-sight range (with XT-1 and XT-4)
• Up to two miles of line-of-sight with handheld devices
• Superheterodyne receiver technology • Power on and RF activity indicators
• Form ”C” relay output • Optional RF supervision
• Weather-resistant case • Antenna (ANT-1A or ANT-2) not included
• Power: 12 VDC • Codes: Over 64,000
• RF frequency: 27.255 MHz • Dimensions: 4.25" W x 6.25" H x 2.5" D
The Model XR-1 1-Channel Mid-range Receiver is 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.

Linear Model XR-4 Extended Range Receiver
Up to 10 miles of line-of-sight range (with XT-1 and XT-4)
• Up to two miles of line-of-sight with handheld devices
• Superheterodyne receiver technology • Power on and RF activity indicators
• Form ”C” relay output • Optional RF supervision
• Weather-resistant case • Antenna (ANT-1A or ANT-2) not included
• Power: 12 VDC • Codes: Over 64,000

The Model XR-4 4-Channel Mid-range Receiver is designed for use in various wireless
remote control applications. When the Model XR-4 receiver detects a signal from its
companion transmitter, it will verify the digital code, activate the correct output channel, and
trigger the remote device connected to the receiver.
The XR-4 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 outputs to follow the transmitter’s inputs, each output
staying activated as long as each transmitter input is activated. Alternately, an auto-restore
option can be selected in the transmitter, causing a momentary receiver output each time
any transmitter input is activated. If the transmitter sends a low battery signal, the receiver’s
low battery output will activate.
