1111. INTRODUCTION

. INTRODUCTION. INTRODUCTION

. INTRODUCTION

The MCT-124 is a hand-held, 4-button PowerCode UHF trans­mitter, 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 once­per-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).

. PREPARATION FOR USE

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.

E. Insert the 3-volt Lithium battery into the battery holder, so that

the (+) and (–) markings on the battery coincide with the
markings on the printed circuit board (close to each battery clip).

F. Put the printed circuit board (with new battery) back in place.
G. Gently press one pushbutton switch and verify that the LED

lights, indicating good battery condition.

3.2 Setting the Mode Selectors

Two DIP switches on the unit’s printed circuit board allow you to
choose between operating modes, as portrayed in Figure 4.

Figure 4. Mode Switch Tasks and Positions

The factory default settings are as shown in Figure 4. To change
modes, shift the proper switch to the opposite position.

IMPORTANT! Due to a programming delay, wait 4 seconds
before testing a newly selected mode.

3.3 Closing the Case

A. Carefully engage the ridge at the top of the base with the dent

at the top of the cover. Press the bottom ends of both halves
of the case together until they click shut.

B. Push the two rubber membranes in place at the sides of the

case - the concave face should be facing out. Verify that they
are seated well within their respective recesses. Work on one
pushbutton at a time, so as not to trigger a distress signal!

C. Re-insert and tighten the screw at the back of the unit.

Note: If the user needs the belt clip (included), position the
belt clip as shown in Figure 5 and insert the screw through
the hole in the clip.

3.4 Learning and Testing

A . You may test the unit only after having conducted a learning

session at the receiver. Refer to the receiver's installation
instructions, and let the receiver "learn" the ID codes
associated with each pushbutton of the transmitter (the two
side-buttons share the 3

rd

ID).

While the target receiver is in the LEARN mode, a transmis­sion from each pushbutton will enroll its individual ID in the
receiver’s memory.
Since the supervision message is always sent with the first
button's ID, it is mandatory to learn the first button's ID.
Failure to do so will disable the supervision function.

ATTENTION! Because each top pushbutton and the two
side buttons together act as independent transmitters with
individual IDs, make sure that all IDs are learned by the
receiver.

B. Stand 3 m (10 ft) away from the receiver and operate the

transmitter.

C. Verify that the transmitter LED lights, indicating good battery

condition. Also verify that the system responds to your trans­mission by performing the
desired function.

D. Operate the transmitter

from various locations
within the area covered by
the receiver to determine
"dead" locations, where
transmission is obstructed
by walls and large objects,
or affected by structural
materials.

. NOTES AND WARNINGS. NOTES AND WARNINGS

. NOTES AND WARNINGS

Visonic wireless systems are very reliable and are tested to high
standards. However, due to their low transmitting power (required
by regulatory authorities), some limitations must be considered:

A. Receivers may be blocked by radio signals on or near their

operating frequencies, regardless of the code selected.

B. A receiver can only respond to one transmitted signal at a time.
C. Wireless equipment should be tested regularly (at least once

a week) to determine whether there are sources of
interference and to protect against faults.

WARNING: Changes or modifications to this unit not expressly
approved by the party responsible for compliance could void the
user's authority to operate the equipment.

This device complies with FCC Rules Part 15. Operation is
subject to two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference
that may be received or that may cause undesired operation.
