Cooper CFR330 Conventional Rate of Rise Heat Detector

The Cooper (Eaton) CFR330 is an essential component for conventional fire systems, specifically engineered for environments where smoke detectors are unsuitable due to high levels of dust, fumes, or steam (e.g., kitchens or boiler rooms). As a rate of rise detector, it provides a fast response to fires that produce a sudden surge in heat, while also acting as a fixed-temperature sensor for slow-burning fires that eventually hit the 60?C threshold. It features a sleek, low-profile design and utilizes advanced light-pipe technology to provide a 360-degree viewable LED for clear status indication. Designed for broad compatibility, it works seamlessly with Cooper, Menvier, and JSB conventional control panels and mounts onto a standard common base for simplified installation and maintenance.
