POTTER CR-135-MP

Product Overview

 The Potter CR-135MP THERMOFLEX MP Series is a single-circuit, Normally Open heat detector with pigtail leads extending through a sealed plate for enhanced protection against corrosive or moisture-laden environments. Designed for areas where condensation or corrosion may damage standard terminal connections, this detector mounts onto a typical cast exterior back box and connects as an initiating device to a fire alarm system. Its internal contacts close upon a rate-of-rise event or when a fixed temperature is reached. The non-metallic diaphragm allows reliable operation in low-temperature environments such as garages, carports, or non-heated spaces. It can be used with an addressing module to identify specific rooms or areas.
