DXT-54 FEATURES

PRODUCT DESCRIPTION

The DXT-54 is a battery powered passive infrared motion detector with

abuilt-in transmitter designed for use with Linear’s DX Format receivers. This transmitter can be used in a variety of motion detection applications. When the passive infrared sensor detects motion in its field of view, the transmitter sends a digitally coded wireless signal to its companion receiver.

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-54 can send two different codes: alarm and low battery.

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 motion detector is mounted indoors in a corner or on a wall between six and eight feet high. The sensor will monitor the infrared level in its detection pattern. If the level increases or decreases rapidly (as when a person or animal moves through the area) the transmitter triggers, sending an alarm signal to the receiver.

DETECTION PATTERN

The unit is powered from a 9-Volt alkaline battery with an expected battery life of up to three years depending on the area’s traffic. When the battery gets low, the test indicator will flash during motion and any alarm transmission will also send a low battery signal to the receiver (some receivers can report low battery, others cannot).

To conserve battery life, the detector will trigger the transmitter only once every four minutes. When testing, remain out of the detection area for at least five minutes before walking in front of the unit to cause an alarm transmission.

For setup and testing, pressing the detector’s test button places the unit in walk test mode for four minutes. The installer can walk in front of the unit while viewing the test indicator behind the detector’s lens to determine the detection area. In walk test, an alarm signal is sent each time the walk test indicator lights.

IMPORTANT !!!

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.

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 modifications 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.
