Features DX Format Wireless Technology

This Linear DX wireless receiver can be used in a variety of remote control applications. When the receiver detects a signal from a transmitter programmed into its memory, the relay output activates. The relay has four optional output configurations.

In a typical installation, the Linear DX wireless receiver is connected to an alarm control panel, door strike, camera, high current relay or some other device. A transmitter is used to activate or control the device. The receiver should be mounted with the supplied mounting bracket indoors or outdoors inside a weather resistant non-metallic housing.

The digital receiver with an isolated relay output designed for use with Linear's DX Format transmitters. The digital DX code format features over a million possible codes. The DX transmitters are precoded at the factory to unique codes, so no field coding is required. Receivers must be programmed to the transmitter's code before system testing and operation. Up to 32 transmitters can be programmed into the receiver's memory. The memory is retained, even without power.

Cutting jumpers select how the relay activates. The factory setting causes the relay to engage for four seconds each activation. Optionally, the relay can be set to engage for one second, toggle on with one activation then off with the next, or latch engaged until reset by pressing the program button.

A nine-inch wire lead serves as the receiver's antenna. The red program indicator lights during RF reception. The installer can verify that signals are being sent from transmitters and diagnose interference problems by viewing the indicator. The indicator also lights during memory programming/erasing and flashes to count the number of transmitters in memory.
