1. INTRODUCTION
The MCT-441 is fully supervised indoor, easy-to-install, PowerCode Gas
detector. The MCT-441 is a natural gas detector designed to send an
alarm when Methane gas is detected. The detectors can be used in a
house, apartment, caravan, mobile home or yacht.
The detectors are powered by 220 VAC. An internal Lithium battery is
used for AC power failure reporting only (the battery does not power the
detector).
The detector can send the following messages to the alarm system
control panel: Gas alarm, gas sensor failure , AC power failure and low
battery voltage .
The MCT-441 is designed for wall mounting and should be placed in a
location where gas presence, for example leakage, is probable.
Upon
gas
detection, an audible buzzer is sounded and
the built-in
transmitter transmits a
digital
message,
composed
of
the
detector's
PowerCode
ID
followed
by
status
messages.
Alarm and
other data are
thus
forwarded
to
the alarm system. A periodic supervision message
is transmitted automatically (see specifications) to inform the alarm
system at regular intervals, of the unit’s active participation in the
system.
The MCT-441 has a 24-bit ID code, randomly selected in the factory
from over 16 million possible combinations. This code is therefore
unique and virtually impossible to reproduce. Compatible PowerCode
receivers are designed to "learn" specific IDs and respond only to
them.
2. SPECIFICATIONS
Compatibility:
Compatible with all PowerMax alarm system family
(PowerMax / P / PowerMax Pro / PowerMaxComplete),
MCR-304 receiver, MCR-308 receiver or any other PowerCode alarm
system.
Gas Type:
Methane (CH4).
Frequency (MHz):
433.92, 868.95, 869.2125 or other frequency
according to local requirements.
Transmitter's ID Code:
24-bit digital word, over 16 million
combinations, pulse width modulation.
Overall Message Length:
36 bits.
Audible Signal Volume:
At least 85 dB at a distance of 3 m.
Response Wave:
8%
±
3% of the gas Lower Explosion Limit (LEL).
Supervision:
Signaling at 15 minute intervals or according to local
standards.
Important:
The detector will not operate without 220V power
connection. In the event of a power failure or where the detector is
not connected to a power source, an AC failure message is sent to
the control panel (will be received by P version 3.0 and up
only). Therefore, when installing the MCT-441, to work with
PowerMax or P
revision 2.9 and down, it is highly
recommended not to
disable
the PowerMax/P
"supervision" function (See "Define Control Panel Parameters" in the
PowerMax Programming Guide or P/PowerMax
Pro/PowerMaxComplete Installer Guide).
ALARM REPORTS:
Gas alarm
Every 20 sec. for the first 3 minutes.
Every 3 min. for the next 27 minutes.
Alarm stops after 30 min., or if the detector goes into "alarm restore".
AC failure
20 seconds after an AC failure occurrence, the AC failure will be
reported - will be received by P (version 3.0 and up) /
PowerMax Pro / PowerMaxComplete. The report will be repeated
every 20 seconds for 3 minutes.
Trouble message
When gas sensor fails, failure message will be received only by
P (version 3 and up) / PowerMax Pro /
PowerMaxComplete.
Relative Humidity:
10% - 90%
Power Source:
220-240V ~ 50 Hz
Battery:
3V Lithium battery, type CR123A, Panasonic or Sanyo
Battery Life Expectancy:
5 years (for typical use, in room temperature)
Operating Temperature:
0

3. INSTALLATION
3.1 Preparing the Installation
A.
The MCT-441 gas detector plugs directly into a standard 220VAC
household switchable outlet (by a switch or circuit breaker).
Note:
The installation must comply with the local authority
electrical standards.
B.
The ventilation slots must not be blocked and the unit must be kept
free of dust.
C.
A proper airflow must be maintained through the unit to obtain an
air sampling of that area of the house where the sensor is situated.
D.
The unit must be installed at least three feet from any gas
appliance to eliminate false alarms but should not be placed
over 20 feet from such appliances.
E.
Install the unit away from any sources of vapor such as alcohol,
liquor, vehicle exhaust, hair spray, cleaning agents, deodorants,
paint, fluorocarbons, or industrial solvents because vapors from
these substances will trigger false alarms.
F.
Do not install the unit directly above cooking appliances, directly
above a sink, or adjacent to extractor fans.
Important!
•
When the alarm sounds, immediately find out the cause and
remedy it or evacuate the building
•
Ventilate the area by opening doors and windows
•
Immediately extinguish any flames or pilot lights
•
Do not operate any electrical devices
•
Determine the source of the gas. Seek a qualified technician or
call your local gas company
3.2 Installing the MCT-441
Warning:
Installation must be performed by a professional
person.
For proper installation, see figure 3 & 4.
3.3 Enrolling the Detector ID into the Target
Receiver's Memory
Refer to the target receiver's installation instructions and follow the
procedure given there for "teaching" IDs. When you are instructed to
initiate a transmission from the MCT-441, press the Test / Silent
button (see Figure 1).
