PRODUCT DESCRIPTION
The DXR-701 is a digital receiver with an isolated relay output designed for use
with Linear’s DX Format transmitters. This 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 congurations.
In a typical installation, the 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 inside a weather resistant non-metallic housing.
The digital DX code format features over a million possible codes. The DX
transmitters are precoded at the factory to unique codes, so no eld 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.
The unit can be powered from a 11-17 VDC or 12-16 VAC power source. The
relay’s normally open and normally closed contacts can switch up to 1 amp at
24 volts AC/DC.
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
ashes to count the number of transmitters in memory. The program button and
indicator function as follows:

IMPORTANT !!!
Linear radio controls provide a reliable communications link and ll an important need in portable
wireless signalling. However, there are some limitations which must be observed.
• 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.
• 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.
• Changes or modications to the device may void FCC compliance.
• Infrequently used radio links should be tested regularly to protect against undetected
interference or fault.
• 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.
