Secutron MRI-4042 Conventional Zone Module

Optimize your fire alarm and security monitoring with the Secutron MRI-4042 Conventional Zone Module — designed to bridge conventional two‑wire detectors and 4–20mA devices into an intelligent control loop. This control panel module from Secutron delivers centralized monitoring, faster alarm reporting, and simplified integration with modern fire alarm control units. The MRI-4042 supports up to 240 MRI‑4000 series devices on a single SLC, reducing wiring complexity and installation time, and it automatically manages Class A or Class B circuits to lower configuration risk. A panel‑controlled LED gives clear local status (flashing in normal operation, steady on in alarm) so technicians can quickly identify and resolve issues. Built to fit a standard 4" square or double‑gang back box and rated for operation between 0°C and 49°C, the module suits a wide range of commercial security and surveillance environments. Use the MRI-4042 to integrate legacy detectors into modern fire alarm networks, streamline maintenance, and improve overall site monitoring.
