Product Description

Shielded receiver in a metal case with an external antenna input for connection to a Model EXA-1000 or EXA-2000 remote antenna, output triggers as long as the transmitter is activated.

Linear's single-channel standard digital receivers are used in wireless security systems and for various remote control applications. The receiver is typically connected to inputs of a hardwired alarm control panel, providing wireless remote capability.

To set a security code, standard digital receivers contain an eight-position coding switch. The switch can be set to one of 256 possible unique codes. Standard digital transmitters also contain a coding switch. Each single-channel transmitter used with the receiver must be set to the exact same security code. The receiver will only activate from transmitters set with a matching code. Multi-channel standard digital transmitters require setting some of the receiver code switches to pre-defined settings to select the activation channel. Refer to the instructions included with multi-channel transmitters for coding requirements.

For power, the DX-12 receiver requires 11-24 VDC or 12-16 VAC. Current consumption for all models is 15 mA during standby and 40 mA when the relay is energized.

Each receiver's relay output provides normally open and normally closed (Form "C"), with dry contacts.
