System Sensor 5604 194F Fixed Temp, Single-Circuit Mechanical Heat Detector

Protect critical spaces with fast, reliable heat detection — the System Sensor 5604 fixed-temperature heat detector is engineered for straightforward installation and consistent performance in fire monitoring and security applications. Designed as a single-circuit mechanical detector with a 194°F activation threshold, the 5604 delivers predictable response where smoke detection is insufficient or where high-heat sources exist. Installers benefit from easy terminal-screw wiring and a reversible mounting bracket that fits single-gang and octagonal back boxes, reducing labor on both new installs and retrofits. The unit’s clear alphanumeric markings identify the activation method and temperature rating at a glance, while the post-activation collector provides a visible indicator of an alarmed device to speed maintenance checks. White low-profile housing blends into commercial and residential interiors, and a 3-year limited warranty supports lifecycle planning for security and fire alarm systems. Ideal for electrical closets, utility rooms, kitchens, and storage areas requiring heat-based detection — add the System Sensor 5604 to your fire protection and monitoring strategy today.
