DXT-31 FEATURES |
PRODUCT DESCRIPTION |
|
The DXT-31 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.
For versatility, any transmitter can be programmed into any receiver channel. Receivers must be programmed to the transmitter 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 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.
NOTE: Functioning of the slide switch marked INSTANT and DELAYED on the bottom of the DXT-31 depends on the receiver used. With some receivers, it has no function.
