Measurement alarm module MDP-8.ZA24/M 8 inputs, 24V power supply, RS-485 port, 2 outputs to valve

Gas detection alarm module – reliable installation safety

This alarm module, designed to work with GAZEX gas detectors, is a key element of the safety system in gas installations. It enables monitoring and control of the hazard status, ensuring a quick response in the event of dangerous gas concentrations. MDP-8.ZA24/M is an advanced device that, thanks to its functionality and reliability, finds application in both two-threshold detection systems and active safety systems.

Functionality and application

The MDP-8.ZA24/M module is designed to work with up to eight gas detectors, both measuring (DEX/P, DG/P types) and threshold (DEX/F, DEX/A, DG/F, DG.EN). The ability to cooperate with different types of detectors makes it a universal solution for a wide range of applications. The device not only monitors the status of the detectors, but also controls their power supply and signals any failures. Additionally, the version with the "Z" designation (as in the MDP-8.ZA24/M model) allows controlling two gas shut-off valves, which increases the safety level of the installation. Communication is via the RS-485 port (MODBUS RTU protocol), allowing integration with building automation systems or data visualization on a PC using the dedicated MD16 View software.

Key features and benefits

• Versatility: Cooperation with various types of GAZEX detectors and external devices.
• Detector status control: Monitoring the current drawn by the detectors and the status of the wired connection – automatic disconnection of the power supply to a faulty detector without affecting the others.
• Configurable alarms: Ability to set two alarm levels for each measuring detector and assign them to two independent zones (S1 and S2).
• Valve control: The "Z" version allows controlling two gas shut-off valves and checking their efficiency.
• Operating modes: Available "QUIET OPERATION", "SERVICE MODE" and "AUTO RESET" modes increase the flexibility of the device.
• Signaling: Clear signaling of alarms and failures using an LCD display, LEDs and an acoustic siren.
• Event memory: Storing the last 1600 events with information about the start and end time and the source of the event facilitates the analysis of the causes of alarms.
• Switching outputs: Four switching outputs allow connecting additional external devices (fans, motors, signaling devices).
• Warranty: 36 months warranty period ensures peace of mind and reliable device operation for a long time.

Thanks to these features, the MDP-8.ZA24/M module is a reliable solution for ensuring safety in gas installations for both professional installers and end users.
