Measurement alarm module MDP-8.A24/M 8 inputs, 24V power supply, RS-485 port

Gas detection alarm module for comprehensive gas detection

The MDP-8.A24/M measurement alarm module is an advanced device designed for monitoring and controlling gas detection systems. It finds application in both dual-threshold systems and active gas installation safety systems, providing reliable protection against hazards. The module allows connection of up to eight detectors, offering flexibility in system configuration. 24V DC power supply and RS-485 communication port ensure easy integration with existing infrastructure.

Functionality and application

MDP-8.A24/M works with measurement and threshold detectors manufactured by GAZEX, as well as devices from other manufacturers equipped with a contact output (using K-8P or K-16P concentrators). It enables control of the current drawn by individual detectors, automatically disconnecting faulty devices, which ensures the continuity of operation of the remaining system elements. Monitoring the status of the wired connection with the detectors allows for quick identification and location of any faults.

The module offers advanced alarm configuration options, including assigning three alarm levels to measurement detectors and two levels for threshold detectors. Additionally, it is possible to calculate the weighted average of TWA and STEL for toxic gases and select measurement units (%, %LEL, mA, ppm). Thanks to the possibility of assigning detectors to two zones (S1 and S2), it is possible to control various external devices depending on the location of the alarm. Versions with the “Z” designation allow controlling two shut-off valves and monitoring their status.

Advantages and benefits

• Versatility: Cooperation with various types of GAZEX detectors and devices from other manufacturers.
• Reliability: Automatic disconnection of faulty detectors and monitoring of the status of wired connections minimize the risk of false alarms and ensure continuous system operation.
• Configuration flexibility: The ability to set different alarm levels, select measurement units, and assign detectors to zones allows you to adapt the system to the specific needs of the installation.
• Communication: RS-485 port enables integration with building management systems (MODBUS RTU) and data visualization using MD16 View software.
• Safety: The ability to control shut-off valves (in “Z” versions) increases the safety level of the gas installation.
• Long-term protection: Manufacturer's warranty – 36 months provides peace of mind for users.
• Easy installation: Removable, self-tightening connectors facilitate system installation and maintenance.
• Diagnostics: Built-in memory stores the last 1600 events with information about time and source of the event, which facilitates failure analysis and system optimization.

The MDP-8.A24/M module is an investment in the safety and reliability of gas detection systems, meeting the expectations of both professional installers and end users.
