Overview
Designed to deliver dependable early warning where it matters most, the Potter Electric Signal THERMOFLEX CR-135W conventional heat detector combines rate-of-rise and 135°F fixed-temperature detection for robust indoor fire monitoring. The CR Series’ dual-action technology triggers on a rapid 15°F-per-minute temperature rise while also activating at the fixed 135°F threshold, giving facilities faster detection without compromising stability in high-ambient settings. With a low-profile, white ceiling-mount form factor and wired connectivity, the CR-135W blends unobtrusively into commercial, retail, healthcare and warehouse environments and integrates smoothly with conventional fire alarm panels and security systems. Coverage extends up to 70 feet between detectors, helping reduce installation time and material costs. Available in single or multiple circuits with open or closed contact configurations, this model supports flexible system design and straightforward maintenance. Backed by Potter’s THERMOFLEX line and a 5-year limited warranty, it’s a reliable choice for building owners and security integrators seeking consistent performance for fire detection, monitoring and surveillance applications. Add the CR-135W to your next fire protection project or contact us to confirm system compatibility.
