Description
The Protectowire PHSC-190-LSZH-M-1000 is a fixed-temperature digital linear heat detector designed to initiate an alarm at 190°F (88°C). It provides continuous line-type heat detection with point sensitivity along the entire cable length.
This model features a Low Smoke Zero Halogen (LSZH) outer jacket suitable for commercial and industrial applications requiring reduced smoke and halogen emissions. The “-M” suffix designates a factory-installed high tensile strength 316 stainless steel messenger wire wound around the detector at approximately one turn per foot, simplifying suspended installations where direct mounting is not practical.
The PHSC-190-LSZH-M model is UL/cUL Listed for spacing up to 50 ft (15.2 m) and FM Approved for spacing up to 30 ft (9.1 m) at the 190°F rating.
