Code-Secure™ Pendant Transmitter

Installation Instructions

,1752'8&7,21

The MCT-231 is a miniature pendant transmitter, designed for
alarm and remote control applications. When activated, the
transmitter sends out a Code Secure™ digital sequence
identifiable by compatible Code Secure™ receivers. Each
transmission comprises a digital sequence that differs from the
one used in the previous transmission and which only the target
receiver can recognize. “Code grabbing” is therefore not possible.

Transmission is initiated by depressing the pushbutton at the
center of the unit. Operating power is obtained from a coin-type,
3-volt lithium battery that can last up to 10 years.

An LED lights during transmission, indicating that the battery
voltage exceeds 2.4 V. If the LED flashes during transmission,
the battery must be replaced immediately. In addition, a “low
battery” report will be transmitted with the outgoing digital
message. Compatible receivers are designed to identify this
report and operate a corresponding output.

All MCT-231 units are supplied with the chain installed, to be
worn around the neck as pendant transmitters. A key ring is also
included in the package, for use in place of the chain.

MPT 1340.

This device complies with Part 15 of the FCC Rules and
RSS-210 of Industry and Science Canada. Operation is subject
to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.

CE Compliance
The 418 MHz and 433.92 MHz models of this device comply

Since the MCT-231 is supplied with the battery already installed,
the unit is practically ready to be tested.

A. "Teach" the target receiver the ID code of the tested

transmitter, as instructed in the target receiver's installation
manual.

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

MCT-231 by depressing its transmit pushbutton. Verify that
the transmitter LED lights, indicating good battery condition.

C. Observe that the receiver’s LED lights steadily, and make sure

that the controlled circuit reacts as programmed.

D. Operate the transmitter from various locations within the area

covered by the target receiver to determine "dead" locations,
where transmission is blocked by walls and large objects, or
affected by structural materials.

Note: If dead/marginal zones are a problem, relocating the
receiver may improve the performance.

The original battery supplied with the transmitter can last up to 10
years if used sparingly (only a single transmission per day).

Battery replacement will therefore be needed very rarely. To
replace the battery proceed as in 3.3, 3.4, 3.5, below.

A. To open the case, refer to Figure 2. Insert an 1/8 inch

screwdriver blade in the slot at the bottom of the case. Press
the blade inward, applying moderate pressure, and while
pressing, swing the handle slightly down until the covers
partially separate.

Warning! Do not try to open the case by inserting a
screwdriver in places other than the slot. This can damage
the transmitter.

B. Gently complete separation of the front and back covers with

your fingers.

5HSODFLQJWKH%DWWHU\

A . Grasp the transmit switch and lift the transmitter module out

of the base.

B . Slide the old battery from under the clip in the direction shown

by the arrow in Figure 3.

C. Hold the 3-volt replacement battery (type CR-2032 or equi-

valent) with the positive (+) side up. Slide the battery all the
way in under the battery clip until it stops..

D . Briefly press the transmit switch (Fig. 3). The on-board LED

should light brightly for 2 seconds.

E . Place the module within the base. Then close the case as

instructed in Para. 3.5 below.

Carefully engage the ridges at the top of the rear cover with the
dents at the top of the front cover. Gently press together the
bottom ends of both covers, until they snap shut.

into the triangle and open it.

C. Remove the triangle.
D. Open the plastic bag which

contains the key-ring kit.

E. Slip the key-ring triangle through

the last link of the keying chain
and install the triangle into the

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

A . Receivers may be blocked by radio signals occurring 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 if 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.
