Secutron MRI-4011-ISO Photoelectric Detector with Isolation

Deliver dependable, early warning for your commercial properties with the Secutron MRI-4011-ISO photoelectric smoke detector. Engineered for accurate fire detection and minimized false alarms, this Secutron smoke detector uses a fully digital protocol and advanced software algorithms to distinguish real fire conditions from nuisance events caused by dust or insects. Certified to UL 268 7th edition and CAN/ULC S529Rev 4, the MRI-4011-ISO also provides loop isolation to keep other devices operational during a fault, and supports up to 240 MRI-4000 series devices on a single SLC loop for scalable security and monitoring deployments. Dual 360° LEDs deliver clear alarm and trouble status at a glance, while compatibility with the MIX-4090 handheld programmer and a full complement of MRI-4000 bases streamlines installation and maintenance. Ideal for commercial buildings, healthcare facilities, and critical infrastructure where reliable surveillance and fire monitoring are essential.
