Description
The MCT-441 are fully supervised indoor, easy-to-install, PowerCode Gas detectors. 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.

Technical information
- Gas Types: Methane (CH4);
- Frequency (MHz): 868MHz;
- 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;
