1. INTRODUCTION

. INTRODUCTION
The MCT-101 (one button), MCT-102 (2 buttons) and MCT-104
(4 buttons) are hand-held, PowerCode UHF transmitters,
especially designed for use in supervised alarm and remote
control systems.
Transmission is activated by pressing any one of the transmit
pushbuttons on the unit. When pressed, each button initiates
transmission of a unique 24-bit PowerCode ID which identifies it
to the target receiver as if it were a separate transmitter. Each
unique ID code is factory-selected from 16 million possible
combinations.
A built-in mode selector allows choosing between continuous
transmission for as long as the button is pressed and timed
3-second transmission, no matter how long the button is pressed.
Another built-in mode selector is used to enable/disable a
once-per-fifteen-minute supervision message (once-per-hour for
the 315 MHz model), or according to local standards.
Since messages transmitted by the MCT-101, -102 and -104 might
collide with other messages sent by other PowerCode transmitters,
a smart anti-collision transmission sequence is used.
Operating power is obtained from an internal long-life 3-volt
lithium thionyl chloride battery. An LED lights during transmission,
indicating the battery voltage condition. If the LED flashes during
transmission, the battery must be replaced immediately. In
addition, a transmitter with a weak battery will automatically add a
“low battery” code to each transmission. Compatible receivers are
designed to identify this code and activate a corresponding output.
Each transmitter of this series is supplied with a belt clip that can
be optionally attached to the unit (see Figure 5).
