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, 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 Grade 2
Class II, and Directive 1999/5/EC.
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.
