INDICATORS

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.

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.

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.

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.

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.

IMPORTANT !!!

Linear radio controls provide a reliable communications link and fill an important need in portable wireless signaling. However, there
are some limitations which must be observed.
1 For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 15 devices. As such,

they have limited transmitter power and therefore limited range.

1 A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals that occur on or

near their operating frequencies, regardless of code settings.

1 Changes or modifications to the device may void FCC compliance.
1 Infrequently used radio links should be tested regularly to protect against undetected interference or fault.
1 A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor or dealer, and these

facts should be communicated to the ultimate users.
