The DXS-31 is a battery powered stationary transmitter designed for use with Linear’s DXS and DX
format receivers. This transmitter can be used in a variety of wireless remote control applications.
Triggering the transmitter with its built-in magnetic switch, an external switch or an external glass
break detector sends a digitally coded wireless signal to its companion receiver.
The digital DXS code format features over a million possible codes. The DXS transmitters are
precoded at the factory to unique codes, so no field coding is required. The DXS-31 can send four
different codes: alarm, restore, low battery and status.
For versatility, any transmitter can be programmed into any receiver channel. Receivers must be
programmed to the transmitter’s code before system testing and operation. Refer to the receiver’s
instructions for details on programming.
In a typical installation, the magnet is mounted on a door or window and the transmitter is mounted
on the frame. When the magnet moves more than 1/2" away from the transmitter, an alarm signal
is sent. When the magnet returns next to the unit, a restore signal is sent. Alarms and restores can
also be sent from external contacts wired to the terminal block. Pressing the case sends a test
transmission that updates the receiver to the current state of the contacts and lights the test indicator.
When the transmitter’s case is open, the transmit indicator will light each time the unit sends an
alarm or restore signal. The indicator is disabled when the case is closed (except for test
transmissions). The indicator will flash during operation and test when the batteries are low.

The transmitter is powered from two 3-Volt #2032 lithium batteries with an expected battery life of
up to 3 years.
Every hour, the DXS-31 will send a status transmission to the receiver. The hourly signal updates
the receiver to the transmitter’s condition. By monitoring status transmissions, the receiver can
determine if a transmitter has a low battery or has been removed from the system. DXS format
receivers can monitor status signals, DX format receivers cannot.
A three-position terminal block is for connection to normally closed external contacts or a normally
open “Window Bug” type glass break sensor. An internal jumper selects which input to use.
Selections are: internal switch only, external switch only, both external and internal switch, and glass
break sensor.
Another internal jumper selects an instant or delayed transmission code. This jumper doesn’t delay
the actual transmissions, but changes the code of the signal sent so the receiver can process the
signal as coming from an entry/exit delay transmitter.
A snap-on transmitter mounting plate is provided for easy installation. The magnet is adjustable with
four height positions. A 1/4" high magnet spacer is also supplied to snap on to the base of the magnet.

Linear radio controls provide a reliable communications link and fill an important need in portable wireless signalling. 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.
