Types of Protectowire Linear Heat Detector

Protectowire Linear Heat Detector is made in multiple temperature ratings to allow for differences in normal or ambient temperature. Guidelines for selecting the proper detector temperature rating are the same as for automatic sprinklers and other heat actuated devices. Refer to the Temperature Rating Chart for proper model selection based upon installation temperature limits.

The Detector’s product range consists of four distinct types of cable. Each designation identifies a specific outer jacket material which has unique characteristics that have been selected to accommodate the widest range of installation environments.

Type EPC

Type EPC Protectowire consists of a durable flame retardant vinyl outer jacket. This series is best described as multi-purpose and is well suited to a wide range of both commercial and industrial applications. The outer jacket provides good all-around performance for most installations. It features low moisture absorption, resistance to many common chemicals, and excellent flexibility at low temperatures. 

Type EPN

Type EPN utilizes a dual jacket consisting of an inner layer of vinyl with an outer film of black weather resistant 612 nylon. This cable is specifically designed for industrial applications such as conveyors, where abrasion resistance is of major importance. In general, the outer nylon sheath substantially improves the cable’s resistance to abrasion, some acids, aggressive salts, oils and petroleum products while maintaining good electrical and mechanical properties.

Type EPR

The EPR series contains an extruded flame retardant jacket of polypropylene elastomer with a special UV stabilizer added to enhance weathering performance. It is intended for a wide range of industrial applications and is characterized by high resiliency, good abrasion resistance, excellent weathering properties and exceptional high temperature performance. EPR provides better overall performance at higher ambient temperatures than either EPC or EPN
