Alarm module MD-4.Z 4 inputs, 230V power supply, 1 output to valve

Gas detection alarm module

The MD-4.Z alarm module is a key element of safety systems for gas installations, designed to work with gas detectors of the DEX/F, DG/F or DG.EN type. The device provides control and power for up to four sensors, enabling the construction of a comprehensive monitoring system. The MD-4.Z module finds application in both Dual-Threshold Gas Detection Systems and Active Gas Installation Safety Systems (ASBIG), ensuring a high level of safety in buildings and installations.

Functionality and application

MD-4.Z not only monitors the status of detectors but also allows control of additional devices – optical and acoustic signaling devices and other installation elements via relay outputs. The version with a valve control output (MD-4.Z) is an integral part of signaling and shut-off systems, meeting the requirements of the Minister of Infrastructure Regulation. This solution is particularly important in facilities where gas safety is a priority. The module can also be used to remotely control shut-off valves, increasing the flexibility and efficiency of the system.

Construction features and parameters

The MD-4.Z module is characterized by a solid construction and ease of installation. 230V power supply ensures reliable operation, and galvanic isolation of the outputs guarantees safety and resistance to interference. It has alarm inputs for integration with fire systems or manual valve shut-off switches and relay outputs for controlling fans or information boards. A built-in 12V= output allows powering additional acoustic and optical signaling devices. This makes MD-4.Z a versatile solution for a wide range of applications in gas detection systems.

The module works with a maximum of 4 detectors and requires a 230V~ power supply. It has 2 alarm outputs 12V=, 2 relay outputs and 2 alarm inputs, as well as an output for controlling a shut-off valve. Additionally, the module has an emergency output indicating the emergency state of the device or lack of power, which increases the reliability of the entire gas detection system.
