TX-91

DESCRIPTION The TX-91, TX-92 and TX-94 are supervised,

digitally-coded radio transmitters designed for remote control and
emergency applications. Each transmitter can be activated by
pressing the pushbutton(s) on the front or by pressing the small
pushbutton on the top. To send a complete signal, press the
transmitter button for a minimum of 2 seconds. The bright red
LED will light as the transmitter is activated. A belt holder and
pocket clip are supplied to attach to the back of the transmitter. A
cover plate is also provided to conceal the top pushbutton if
required.

The transmitters are supervised for low battery, alarm and status
reporting. The TX series transmitters are compatible with any
Linear SX format supervised security receiver. The transmitter
sends hourly status reports. A test report can be sent by pressing
a hidden button on the rear of the transmitter.

Coding switches are not required or used in the TX series transmitters.
Each transmitter is pre-coded at the factory to a unique code. With the
SX format, there are more than sixteen million codes possible.

The transmitter is powered by two self-contained type 2032 3-volt
lithium batteries (included). When the batteries voltage gets low,
a low battery report is sent with any alarm, test or status report to
notify the receiver. The red LED will blink when the transmitter is
activated with low batteries.

TX-91 - Two-channel transmitter with a button on the front and the
top (each button performs a separate function).

TX-92 - Three-channel transmitter with two buttons on the front and
one button on the top (each button performs a separate function).

TX-94 - Five-channel transmitter with four buttons on the front and
one button on the top (each button performs a separate function).

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.
