Linear Door/Window Home Security External
Contact and Glass Break Sensor DXT-31  
Linear DXT-31 Door/Window External Contact and Glass Break Sensor The Model DXT-31 Door/Window Transmitter is a battery powered stationary transmitter designed for use with Linear's DX Format receivers. This
transmitter can be used in a limitless number 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. Pressing
the transmitter's case sends a test transmission.
The digital DX code format features over a million possible codes. The DX
transmitters are precoded at the factory to unique codes, so no field coding is required. The DXT-31 can send three different codes: alarm,
restore and low battery.
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 indicates the current state of the contacts.
The transmitter is powered from two 3-Volt #2032 lithium batteries
with an expected battery life of up to 3 years. The red test/operate indicator lights during operation and test. It will blink during
operation and test when the batteries are low.
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.
A snap-on transmitter mounting plate is provided for
easy installation. The magnet has four height positions. An additional snap-on magnet spacer is provided for a total of eight magnet
positions.
