1. INTRODUCTION
The MCT-234 and MCT-234 NB (Narrow Band) are miniature
CodeSecure™ 4-button (4-function) transmitters, designed for use with
advanced, high-security alarm and remote control systems such as the
Visonic Ltd. UL-listed model PowerMax. For UL installations, use UL
listed control panel, model PowerMax+ only.
Transmission is initiated by pressing any one of the four recessed
pushbuttons. Upon pressing a specific button, the transmitter transmits a
CodeSecure™ digital sequence identifiable by compatible CodeSecure™
receivers, and a 4-bit function code associated with the button that was
pressed.
The next time a button is pressed, the transmitter will transmit a digital
sequence that differs from the one used in the previous transmission and
the respective function code. As a result, malicious "code grabbing" is
virtually impossible.
Operating power is obtained as follows:
MCT-234: 12V alkaline battery
MCT-234 NB: 3V Lithium battery.
A red LED lights during transmission as long as the battery voltage
exceeds:
MCT-234: 8.6 V
MCT-234 NB: 2.6V.
If the LED flashes during transmission, the battery must be replaced
without delay. 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.
Each transmitter is supplied with a small key ring.
2. SPECIFICATIONS
Frequency (MHz):
MCT-234: 315, 433.92, 868.95, or other per local requirements (UL has
only investigated at 315 MHz).
MCT-234 NB: 869.2625 (25KHz channel bandwidth)
Modulation: ASK (ON-OFF keying)
Coding: 28-bit ID, 4-bit function code and 32-bit rolling code.
Transmission Duration: Each button press causes transmission for up to
2 seconds.
Power Supply:
MCT-234: 12 V alkaline battery, 55mA/h, type GP 23A or equivalent. For
UL installations, use battery manufactured By GP.
MCT-234 NB: 3V battery, CR-2032
Current Consumption (Transmission): 11mA
Battery Life Expectancy (For typical use):
MCT-234: 1 year
MCT-234 NB: 3 years
Battery Supervision:
Good battery - LED lights steadily upon transmission.
Low battery - LED flickers upon transmission.
Note: If transmission is still possible despite the battery condition, the unit
will send a low battery signal to the receiver.
Operating Temperature: 0° to 49° C (32° to 120° F).
Dimensions:
MCT-234: 53.5 x 31.5 x 12.5 mm (2-1/8 x 1-1/4 x 1/2 in.).
MCT-234 NB: 59.7 x 34.2 x 12.5 mm (2-3/8 x 1-3/8 x 1 in.)
Weight (including battery) : 21 g (3/4 oz).
Color: Black
Compliance with Standards: FCC Part 15, EN 50131-1, EN 50131-3, EN
50131-6, Type C Grade 2 Class II. MCT-234 Certified by Applica T&C. MCT-
234 NB was not evaluated for EN.
3. TESTING AND MAINTENANCE
3.1 Testing a New Unit
Since the MCT-234 is supplied with the battery already installed, the unit
is practically ready to be tested.

IMPORTANT! Before testing, "teach" the target receiver the ID code of
the MCT-234, as instructed in the receiver's programming manual.
A. Stand 3 m (10 ft) away from a target receiver (or wireless control
panel) and press the MCT-234 button marked with a closed padlock
icon. Verify that the transmit LED lights.
B. Make sure that the receiver (or control panel) responds as programmed
and as stated in the receiver's instruction manual.
C. Operate the transmitter from various locations within the area covered
by the 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.
3.2 Replacing the Battery
The battery should be replaced once every 1 year (MCT-234) / 3 years
(MCT-234 NB) or upon observing that the LED flickers when transmitting.
A. Use a small Phillips screwdriver to open the miniature screw at the
back of the unit. Take care not to lose the screw.
B. Put the unit down and extract the battery from its holder (see Figure
2).
Note: Make sure the elastic pad within the cover remains in place. Put
it back in place if it falls off.
C. Insert the new battery, observe polarity.
D. Test the unit by momentarily pressing one of the transmit switches.
The LED indicator should light.
E. Put the cover back on and re-attach it with the screw.
3.3 Cleaning
The transmitter may get dirty if touched with greasy fingers. Clean it only
with a soft cloth or sponge moistened lightly with a mixture of water and
mild detergent, and wipe it dry immediately.
The use of abrasives of any kind is strictly forbidden. Also never use
solvents such as kerosene, acetone or thinner.
4. MISCELLANEOUS COMMENTS
4.1 Product Limitations
Visonic Ltd. wireless systems are very reliable and are tested to high
standards. However, due to their low transmitting power and limited range
(required by FCC 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 to determine whether there
are sources of interference and to protect against faults.
4.2 Compliance with Standards
This device complies with the essential requirements and provisions of
Directive 1999/5/EC of the European Parliament and of the Council of 9
March 1999 on radio and telecommunications terminal equipment.
The 315 MHz model of this device complies with Part 15 of the FCC
Rules. Operation is subject to the following two conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any
interference that may be received, including interference that may cause
undesired operation.
Note: MCT-234 only was evaluated by UL. MCT-234 NB was not
evaluated by UL.
The user is cautioned that changes or modifications to the unit, not
expressly approved by Visonic Ltd., could void the user's FCC
authority to operate the equipment.
