Alarm module MD-2.A 2 inputs, 12V power supply

Gas detection alarm module – reliable protection for installations

The MD-2.A alarm module is a key element of a gas detection system, designed to work with dual-threshold detectors of the DEX/F, DG/F and DG.EN types. The device provides not only control and power supply for sensors, but also enables control of optical and acoustic signaling devices and cooperation with other safety devices. It is an indispensable solution for both professional gas system installers and end-users who care about safety in their homes or businesses.

Functionality and application

MD-2.A is designed to operate in a Dual-Threshold Gas Detection System and an Active Gas Installation Safety System (ASBIG). The module can control one or two detectors, and in the version with a shut-off valve control output, it is an integral part of a signaling and shut-off system compliant with the Minister of Infrastructure Regulation. This ensures effective protection against gas leaks and minimizes the risk of potential hazards.

The module finds application in:

• Homes and apartments with gas installation
• Commercial and industrial buildings
• Gas boiler rooms
• Automotive workshops
• Heating installations using gas

Key features and benefits

• Versatility: Compatible with various types of GAZEX detectors (DEX/F, DG/F, DG.EN).
• Alarm signaling: Equipped with optical (LED) and acoustic (internal siren) signaling, informing about exceeding gas concentration thresholds. Alarm status memory facilitates event analysis.
• Control outputs: Has relay outputs for connecting additional signaling devices, fans, contactors or information boards. Enables integration with other safety systems.
• Alarm input: Possibility of connection to fire alarm systems or a manual valve shut-off for increased safety level.
• Power supply for additional devices: 12V= outputs allow powering additional acoustic and optical signaling devices without the need for additional power supplies.
• Emergency output: Indicates the emergency status of the module or lack of power, allowing for a quick response in case of problems.
• Solid construction: ABS + PC housing with IP54 protection degree ensures resistance to weather conditions and mechanical damage. 3-point mounting guarantees device stability.

The MD-2.A module allows control of up to two detectors, operates at 12V= voltage and has two alarm control outputs 12V= and two relay outputs.

The MD-2.A module is an investment in safety that provides peace of mind for both end-users and professionals responsible for gas installations. Thanks to its functionality and reliability, it is an ideal solution for anyone who values a high level of protection against hazards related to gas leaks.
