The Secutron 4000 Series Non-Isolated Photoelectric Detector delivers precision smoke detection using advanced optical sensing technology. Engineered for applications requiring reliable photoelectric response, this detector excels at identifying slow-burning fires that produce visible smoke particles. The non-isolated configuration integrates seamlessly into conventional fire alarm systems, offering straightforward installation and maintenance. Built to commercial-grade standards, it provides consistent performance across diverse environments. Ideal for facilities prioritizing early detection of smoldering fire conditions, this detector combines proven photoelectric methodology with Secutron's reputation for dependable fire safety solutions.

The MRI-4011 and MRI-4011-ISO are hardwired photoelectric smoke detectors designed to provide prompt fire detection while reducing the likelihood of nuisance alarms. Every sensor in the MRI-4000 series utilizes a fully digital communication protocol to interface with control panels.
