Potter CR-135CW ROR Heat Detector, Normally Closed Contact, 135°F, White

For reliable, early fire detection in commercial and industrial installations, the Potter Electric Signal CR-135CW ROR heat detector delivers fast, actionable alarms that integrate easily into security and monitoring systems. This heat detector combines a restorable Rate-of-Rise (activates at a 15F per minute increase) with a non-restorable 135F fixed-temperature element to catch both rapidly developing and sustained high-temperature events. The normally closed (NC) contact and dual AC/DC power compatibility (125V AC / 28V DC) simplify wiring to existing fire panels and low-voltage control systems, cutting installation time and cost.

Designed for up to 70' inter-detector spacing and a low-profile white housing, the CR-135CW fits discreetly into retail, warehousing, and institutional spaces where both aesthetics and performance matter. Specified by contractors and system integrators for robust fire detection and integration with security, surveillance, and building monitoring platforms, it reduces downtime with a restorable ROR element and is supported by a 5-year limited warranty. Add the CR-135CW to your next safety specification or contact our sales team to ensure dependable fire monitoring across your site.
