PLR THERMAL DETECTOR

The detector is made in multiple temperature ratings to allow for differences in normal 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 two distinct types of cable. Standard PHSC models and low resistance “Universal” versions designated with the prefix PLR. Each model number designation also identifies a specific outer jacket material carefully selected to accommodate the widest range of installation environments. All specifications are subject to change without notice.

PLR-R – Type PLR consists of a polypropylene elastomer jacket and is designed for universal compatibility through the use of special low-resistance inner conductors. Features of this jacket include good abrasion resistance, chemical resistance, and weather resistance.

PLR-CR – Type PLR -CR is constructed with low resistance inner conductors, allowing for longer detector zone lengths on most types of fire alarm panels including addressable panels. Utilizing a high performance fluoropolymer outer jacket, this detector is specifically designed for use in applications where extreme environment and product criteria must be met. The flame retardant, low smoke jacket provides excellent abrasion resistance and mechanical properties over a broad range of applications. It provides excellent chemical and permeation resistance to a wide range of acids, bases, and organic solvents, as well as simple gases. In addition, the jacket exhibits very little change in tensile properties upon outdoor exposure to sunlight and weather.
