Alarm module MD-2.Z 2 inputs, 230V power supply, 1 output to valve

Gas detection alarm module – reliable installation safety

The MD-2.Z 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 not only controls and powers the sensors, but also enables a quick response in the event of a dangerous gas concentration, which is extremely important for both the safety of users and the integrity of the installation. Thanks to the ability to control a shut-off valve (in the MD-2.Z version), the module is an integral part of signaling and shut-off systems compliant with applicable standards.

Functionality and application

MD-2.Z is designed to work with two gas detectors, monitoring their status and responding to alarms. It can be used in a Dual Gas Detection System and in an Active Gas Installation Safety System GX (ASBIG). In addition to the basic alarm function, the module allows you to control additional devices – optical and acoustic signaling devices, fans or contactors – which increases the functionality of the entire system. The version with a shut-off valve control output allows for automatic closure of the gas supply in the event of a failure, minimizing the risk of serious consequences.

Key features and benefits

• Versatility: Compatible with various types of gas detectors (DEX/F, DG/F, DG.EN), which facilitates integration with existing systems.
• Alarm signaling: Clear optical and acoustic signaling of the alarm status of the detector and control outputs ensures a quick response to the threat.
• Safety: The ability to control a shut-off valve when a dangerous gas concentration is detected minimizes the risk of explosion or poisoning.
• Expandability: Relay outputs allow you to connect additional signaling and control devices, adapting the system to individual needs.
• Connection monitoring: The module monitors the status of the wired connection with the detectors, signaling any breaks in the circuit.
• 230V power supply: Standard 230V power supply facilitates installation and integration with the existing electrical infrastructure of the building.
• Alarm input: The ability to connect to fire alarm systems or a manual valve shut-off increases the level of installation safety.

The MD-2.Z module is a reliable solution for ensuring safety in gas installations, meeting stringent standards and legal requirements. Its functionality and ease of integration make it an ideal choice for both professional installers and end-users who care about their own safety and the safety of their loved ones.
