DX  Transmitters
Performance-enhanced products of  Standard Digital line. DX uses optimized pulse position based RF technology in 1-, 2-, 4-, and 8-channel receivers that support up to 32 quick-learn transmitters. It has a million plus code availability.

DXS Supervised  Transmitters
Designates fully supervised models of these same receivers and transmitters. Up to 1,500 feet of range.

SX Transmitters
Linear's best line of wireless add-ons. Our most powerful and intelligent receiver uses SAW-based superheterodyne technology and is ideal for high-end hybrid security systems. It has a 1,500 foot range, 16 million code availability, and full supervision for 64 channels and 8 zones. Transmitters include stationary models, handhelds, panics, and bill traps.

XTended Range
 Users can tailor long-distance links ( up to 10 miles ) to their needs — remote monitoring, switching systems, networking, security, remote control. Different models and channel combinations can be mixed and matched to configure very sophisticated systems.

XT-1: 1-Channel Stationary Mid-range Transmitter

XT-4: 4-Channel Stationary Mid-range Transmitter

The Model XT-1 1-Channel Stationary Mid-range Transmitter is 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 mA 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. Features Up to 10 miles of line-of-sight range Over 64,000 Codes RF transmit LED Accepts N/O or N/C inputs Complete RF supervision, field enabled Fully supervised (loop status, low battery, link integrity) Weather-Resistant Case RF frequency: 27.255 MHz 4.25" W x 6.25" H x 2.5" D

The Model XT-4 4-Channel Stationary Mid-range Transmitter is designed for use in various wireless remote control applications. When triggered with an external switch, the Model XT-4 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-4 transmitter has full supervision capabilities. If the status option is selected, the XT-4 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 outputs to follow the transmitter's inputs, staying activated as long as each transmitter input is activated. Alternately, an auto-restore option can be selected, causing a momentary receiver output each time any transmitter input is activated. Each input can be configured for either N/O or N/C contacts (switch selectable). Power for the XT-4 transmitter can come from an external regulated 12 VDC 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-4 draws about 15 mA standby, and about two amps during transmissions.
