Linear DXSR 1508 User Manual

PRODUCT DESCRIPTION  
The DXSR-1504 and DXSR-1508 are four and eight channel supervised digital receivers with solid state outputs designed  
for use with Linear’s DX and DXS Format transmitters. These receivers can be used in a variety of security and remote  
control applications. When the receiver detects a signal from a transmitter programmed into its memory, the appropriate  
channel output activates. The channel outputs have three optional configurations; momentary, toggle on/off, and latch until  
restored. Status and low battery outputs are for supervisory indications. Cutting jumpers select which channels require  
supervisory status reports from transmitters.  
DXSR-1504  
DXSR-1508  
Each unit incorporates a dual high-sensitivity superheterodyne diversity receiver with two whip antennas. This type of  
receiver provides superior performance by preventing loss of signal due to multi-path interference.  
SUPERVISED  
In a typical installation, the receiver is connected to an alarm control panel, door strike, camera, high current relay or some  
other devices. Transmitters are used to activate or control the devices. The receiver should be mounted indoors or inside  
a weather resistant non-metallic housing for outdoor use.  
DIGITAL RECEIVERS  
The digital DX/DXS code format features over a million possible codes. The transmitters are precoded at the factory to  
unique codes, so no field coding is required. For versatility, any transmitter can be programmed into any receiver channel.  
Receivers must be programmed to recognize the transmitter’s code before system testing and operation. Up to 32  
transmitters can be programmed into the receiver. Each button on multi-button portable transmitters send a unique code,  
and are programmed as separate transmitters.  
Installation Instructions  
The CHANNEL display shows the channels activated and the presence of radio activity. Individual indicators for ALARM,  
STATUS, and LOW BATT show the supervisory status of each receiver channel. All outputs can be configured for normally  
open or normally closed.  
The units can be powered from a 10.2-14.4 VDC or 12-16 VAC power source. The units will draw about 35 mA standby  
and up to 120 mA in alarm.
