Gas detector DD-MT/AP methane (selective), 10/20/30% LEL, relay output, p-p sensor, 12V power supply (for burglary alarm systems)

Safety in Your Home – Methane Detector DD-MT/AP

This gas detector, designed for burglar alarm systems, provides continuous monitoring of methane concentration in enclosed spaces. Its task is to quickly detect dangerous leaks and notify you using optical and acoustic signals, as well as transmit information to the alarm system. The device is particularly recommended for kitchens, where the risk of gas leakage is higher, but it will also work in other rooms with potential methane sources.

The DD-MT/AP detector is a reliable solution for both alarm system installers and end-users looking for effective protection against gas poisoning. The replaceable sensor module simplifies maintenance and reduces operating costs, while the high sensitivity and selectivity of the sensor minimize the risk of false alarms.

Functionality and Application

The detector finds wide application in various places:

• Kitchens with instantaneous water heaters and gas ovens.
• Rooms with fireplaces or solid fuel stoves.
• Gas or oil boiler rooms (without flue gas sensors).
• Attached garages (monitoring exhaust fumes or LPG leaks).
• Rooms with air conditioning, refrigerated counters and refrigeration units.
• Refrigerant warehouses.
• Cars and commercial vehicles.

Thanks to its design and ability to integrate with the alarm system, this detector is an integral part of a comprehensive building security system. The relay output allows connection to an alarm panel or other signaling device.

Technical Characteristics and Additional Information

The DD-MT/AP detector is characterized by high measurement accuracy and stable operation thanks to the built-in microprocessor and thermal compensation circuit. It has three factory-set alarm thresholds (10%, 20%, 30% LEL), which can be adjusted to individual needs. The alarm is signaled by red LEDs and an audible siren (with the possibility of disabling). The device is powered by 12V DC, ensuring compatibility with most alarm systems. The detector housing is made of high-quality plastic, ensuring durability and resistance to mechanical damage. Remember to calibrate regularly every 3 years – exceeding this period is signaled optically. The detector has been calibrated in its own GAZEX Calibrating Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees the accuracy and reliability of measurements.
