PWSH Splice Housing

The PWSH splice housing is designed to safeguard Protectowire line type heat detector field splices. Consisting of PA11 nylon (or equivalent) construction, the device is suitable for a wide range of ambient temperature applications.

EPC (Extruded Polyvinyl Chloride) – is a durable flame-retardant vinyl outer jacket designed for interior commercial and industrial applications. Features of this jacket include low moisture absorption, resistance to many common chemicals, and excellent flexibility at low temperatures.

XCR (Extreme Corrosion Resistance) – is a high-performance fluoropolymer jacket designed for both interior and exterior environments. Features of this jacket include excellent chemical resistance, abrasion resistance, weather resistance, and high-temperature performance. XCR is the only heat detector that is FM-approved for corrosive environments.

LSZH (Low Smoke Zero Halogen) – is a durable outer jacket designed for interior commercial and industrial applications requiring low smoke zero halogen performance. Features of this jacket include low moisture absorption, resistance to many common chemicals, and excellent flexibility at low temperatures.

XLT (Extreme Low Temperature) – is an outer jacket specifically selected for cold storage and freezers. Features of this jacket include low moisture absorption and excellent performance in extremely low temperatures. This detector has been UL and FM tested to –60°F (–51°C)

EPR (Extruded Polypropylene Rubber) – is an outer jacket designed for both interior and exterior environments. Features of this jacket include good abrasion resistance, chemical resistance, and weather resistance over a wide temperature range.

  • PWSH is available for PHSC and CTI.
Protectowire offers two versions of the PWSH splice housing to ensure the integrity and protection of field splices in line-type heat detection systems: the PWSH-PHSC and PWSH-CTI. Both models are constructed from durable PA11 nylon (or equivalent), tested to the IP66 environmental standard, and designed to perform reliably in a wide ambient temperature range from -40°F to 176°F (-40°C to 80°C). The PWSH-PHSC is equipped with a PWSC terminal block and is compatible with PHSC and PLR detector models, while the PWSH-CTI includes a CTIC terminal block specifically for use with CTI detectors. Each housing features two SR-502N strain relief connectors and supports cable outer jacket diameters from 0.08” to 0.24” (2 mm to 6 mm), providing robust mechanical protection in a low-profile design.
