1. INTRODUCTION
. INTRODUCTION. INTRODUCTION
. INTRODUCTION
The MCT-124 is a hand-held, 4-button PowerCode UHF trans-
mitter, designed specifically for distress signaling and other tasks
in supervised alarm and remote control systems.
To prevent accidental distress signaling, the two side buttons (one
of which is hidden in Figure 1) have to be pressed simultaneously
to transmit a unique 24-bit PowerCode ID, interpreted as a call for
help. The two buttons at the top can be used to arm/disarm an
alarm system or to activate auxiliary devices. Pressing any one of
the 2 top buttons initiates transmission of a unique 24-bit ID
linked to the specific button, as if it were a separate transmitter.
Each PowerCode ID 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-hour (or according to local standards) supervision message.
Since messages transmitted by the MCT-124 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 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 is supplied with a belt clip that can be optionally
attached to the unit (see Figure 5).

3.1 Battery Installation
A. Remove the screw at the back of the unit.
B. Insert a 1/8 inch screwdriver in the slot either at the top or at
the bottom of the case. Rotate the screwdriver handle slightly
until one edge of the cover disengages from the base.
C. Swing up the free end of the cover and separate the cover
from the base.
Figure 2. Opening the Case
D. Extract the transmitter module from the base by grasping the
battery holder and pulling out.
CAUTION! The two rubber membranes at the sides may fall
off. It is advisable to pull them out and put them temporarily
aside, so that they would not get lost.
