Alarm module MD-2 2 inputs, power supply 230V

Gas detection alarm module – reliable protection for installations

The MD-2 alarm module is a key component of gas detection systems, designed to work with dual-threshold detectors of the DEX/F and DG/F types. The device provides control and power for up to two sensors, offering comprehensive protection in a Dual-Threshold Gas Detection System or an Active Gas Installation Safety System (ASBIG) of the GX type. MD-2 not only monitors the status of detectors but also enables control of external optical and acoustic signaling devices, as well as cooperation with other devices via relay outputs.

Functionality and application

The MD-2 module is a versatile solution, finding application in both commercial and domestic installations. Thanks to the ability to control a shut-off valve (in MD-2.Z versions), it is an integral part of signaling and shut-off systems, meeting the stringent requirements of the Minister of Infrastructure Regulation. The device works well in places requiring continuous monitoring of gas concentration, ensuring a quick response in the event of exceeding permissible norms.

Key features and benefits

• Control for two detectors: Monitoring two independent measurement points increases safety and detection accuracy.
• Alarm signaling: Clear optical and acoustic signaling of the alarm status facilitates quick identification of the hazard.
• Relay outputs: The ability to connect additional devices (fans, contactors, information boards) expands the functionality of the system.
• Alarm input: Compatibility with fire systems or manual valve shut-offs increases installation flexibility.
• Emergency output: Information about the module's emergency status or lack of power allows for quick diagnosis and repair of the fault.
• Powering additional devices: Possibility of powering additional acoustic and optical signaling devices from the 12V= output.
• Versions with valve control output: MD-2.Z models enable automatic shut-off of gas supply in the event of a hazard, ensuring maximum safety.
• Solid construction: The ABS housing provides durability and resistance to mechanical damage and external factors (IP54).
• Easy installation: Compact dimensions (240 x 215 x 115 mm) facilitate installation in limited space.

The MD-2 module allows connection to two detectors operating at 230V~, has two 12V= alarm control outputs and two relay outputs. Two alarm inputs are also available.

The MD-2 module is a reliable solution for anyone who cares about the safety of gas installations – both for professional installers and end users. Its versatility, functionality and ease of installation make it an ideal choice for building an effective gas detection system.
