Secutron MRI-4030-ISO Tri-Mode Heat Detector with Isolation

For dependable, low-maintenance fire monitoring in commercial and industrial environments, the Secutron MRI-4030-ISO tri-mode heat detector delivers fast, accurate detection while minimizing nuisance alarms. As a Secutron heat detector engineered for modern fire alarm systems, the MRI-4030-ISO uses a fully digital protocol and advanced software algorithms to provide multiple sensing modes and selectable sensitivity — giving you reliable detection without frequent false dispatches.

The isolation (ISO) model protects the signaling line circuit (SLC) from wiring faults and helps keep your security and fire alarm network online. The unit supports up to 240 MRI-4000 series devices on a single SLC, making it ideal for scalable installations across commercial, healthcare, education, and industrial sites. Anti-tamper protection, multi-color LED status indicators, and easy addressing via the MIX-4090 handheld programmer simplify maintenance and reduce service time.

Specify the Secutron MRI-4030-ISO for integrated security and life-safety systems where dependable monitoring, minimal downtime, and streamlined serviceability are priorities. Contact your reseller or add the MRI-4030-ISO to your next fire alarm project.
