Control module MD-1.Z/M 1 input, as above + RS-485 port

Control module for gas detection systems

The MD-1.Z/M control module is a key component of gas detection systems, designed to work with threshold detectors of the DEX/F, DEX/A, DG/F or DG.EN type. The device allows control and power supply of one detector, as well as integration with gas installation safety systems, such as the Active Gas Installation Safety System (ASBIG). It is a reliable solution for both professional installers and end-users, providing safety and control over potential hazards.

Functionality and application

The MD-1.Z/M module offers a wide range of functionalities, including optical signaling of alarm states, an alarm input for cooperation with fire protection systems, and relay outputs for controlling additional devices – fans, contactors or information boards. The /M version is equipped with an RS-485 port, which enables connection to the Digital Gas Detection System (DGD) and configuration and data reading using the dedicated “DETnet View” software. This makes it possible to remotely monitor the system status and react quickly in the event of a hazard. This module finds application in residential and industrial buildings, where gas concentration control and rapid response to potential leaks are required.

Key features and benefits

• Versatility: Compatible with various types of gas detectors (DEX/F, DEX/A, DG/F, DG.EN), providing flexibility in system selection.
• Integration with safety systems: The ability to cooperate with fire protection systems and ASBIG increases the level of safety in the installation.
• Remote monitoring and configuration: The RS-485 port and “DETnet View” software enable remote control and configuration of the module.
• Alarm signaling: 12V= alarm outputs allow connection of additional acoustic and optical signaling devices for effective hazard warning.
• Emergency output: The “FAILURE” relay output informs about the emergency state of the module or lack of power supply, which facilitates diagnostics and system maintenance.
• Automatic power backup (in MD-1.Z version): Ensures continuous system operation even in the event of a mains voltage failure.
• Compliance with standards: The module is a component of a “signaling-shut-off system” compliant with the Regulation of the Minister of Infrastructure of the Republic of Poland of April 12, 2002, which guarantees its compliance with applicable regulations.

The MD-1.Z/M module supports a maximum of 1 detector, has 2 alarm control outputs 12V= and 2 relay control outputs. It is equipped with an emergency control output and a digital RS-485 interface. The MD-1.Z version has emergency power backup, and the supply voltage is 230V~. The module dimensions are 165 x 190 x 90 mm.

The MD-1.Z/M module is a reliable solution for anyone who cares about safety in gas installations – both for professionals installing gas detection systems and for end-users expecting effective protection against potential hazards. Its versatility and ease of integration make it an ideal choice for a variety of applications.
