Potter CR-135MP2 THERMOFLEX CR-MP Series Indoor Outdoor Dual Action Heat Detector, 135°F, Weatherproof

Dependable, weatherproof fire detection for challenging indoor/outdoor environments. The Potter Electric Signal CR-135MP2 THERMOFLEX heat detector delivers dual-action protection — rate-of-rise sensitivity plus a 135°F fixed-temperature trip — to detect both rapid temperature spikes and sustained overheating. Built with factory-sealed pigtail leads and a corrosion-resistant mounting plate, this detector resists condensation and corrosive atmospheres, making it ideal for electrical rooms, garages, carports and other monitored spaces.

Designed for easy integration with existing fire alarm and monitoring systems, the CR-135MP2 mounts to a standard cast exterior back box and operates across a broad -40°F to 250°F range. The secure fusible-link mechanism latches contacts on alarm for reliable annunciation to security and surveillance platforms. With up to 70' inter-detector spacing and 28V DC compatibility, it supports efficient system layouts and reduces installation costs.

Specify the Potter CR-135MP2 for robust, low-maintenance heat detection where weatherproofing and accurate fire alarm monitoring are essential. Contact your supplier to add it to electrical rooms, trash compactors or any critical monitored zone.
