Heat detectors are essential fire detection devices that respond to increases in temperature, making them ideal for environments where smoke detectors may cause false alarms, such as kitchens, garages, attics, and industrial areas with dust or fumes. Our inventory includes rate-of-rise heat detectors, fixed-temperature models (135°F and other ratings), addressable photo\/thermal combination detectors, and explosion-proof models for hazardous locations. UL-listed for reliable fire protection in commercial and residential applications.\u003c\/p\u003e","published_at":"2026-01-08T11:27:28-06:00","sort_order":"best-selling","template_suffix":"abc","disjunctive":true,"rules":[{"column":"tag","relation":"equals","condition":"Fire \u003e Fire Detection Devices \u003e Heat Detector"}],"published_scope":"global","image":{"created_at":"2026-01-12T08:16:44-06:00","alt":null,"width":300,"height":300,"src":"\/\/www.fireandsafetyplus.com\/cdn\/shop\/collections\/c5dd27b0-3W-MX916.jpg?v=1768227404"}},{"id":301937950785,"handle":"quick-order","title":"Quick Order","updated_at":"2026-06-29T12:20:03-05:00","body_html":null,"published_at":"2026-02-18T13:35:25-06:00","sort_order":"best-selling","template_suffix":"quick","disjunctive":false,"rules":[{"column":"variant_price","relation":"greater_than","condition":"0"}],"published_scope":"web"}]

The THERMOFLEX® CF/CR Series standard heat detectors are available in single or multiple circuits with open or closed contact configurations. THERMOFLEX® CF/CR Series detectors are available in 135°F, 165°F, 200°F, and 285°F versions.
THERMOFLEX® CF Series
The CF Series detectors are Fixed Temperature only. They will operate when the detector reaches the applicable temperature. Fixed Temperature detectors are non-restorable.
THERMOFLEX® CR Series
The CR Series detectors are combination Rate-of-Rise and Fixed Temperature. The Rate-of-Rise function allows the detector to operate when the temperature at the detector increases at a rate of 15°F per minute. The Fixed Temperature portion will cause the detector to operate when it reaches the applicable temperature. The Rate-of-Rise portion of the detector is restorable; however the Fixed Temperature portion is non-restorable.
