Overview
Protect critical spaces with dependable thermal detection from the System Sensor 5623 fixed-temperature heat detector. Designed for commercial and industrial security and monitoring applications, this dual-circuit mechanical detector provides a clear, single-purpose 135°F trip point to minimize nuisance alarms while delivering reliable fire detection where smoke detectors may not be ideal. The 5623’s dual-circuit architecture improves system redundancy and simplifies wiring integration with fire panels and building monitoring systems, helping you maintain continuous protection and compliance.
Installation is faster and more flexible—mount directly to single-gang or octagonal back boxes and choose flush or surface mounting with the reversible bracket. After activation, the visible collector drops to make post-alarm identification and maintenance quick and efficient. As a wired, fixed-temperature heat detector from System Sensor, the 5623 is optimized for use in mechanical rooms, attics, kitchens, and other challenging environments where thermal sensing is preferred over smoke-based detection. Specify the 5623 to strengthen your facility’s fire and security surveillance strategy—contact our sales team or add to your next project order to integrate reliable heat monitoring into your protection plan.
