The SG-42SK2 is a replacement hardware accessory for Protectowire linear heat detection (LHD) systems. It serves as a termination, splice, or mounting accessory used to support and secure the continuous heat-sensing cable along its run. Replacement parts of this type keep an installed Protectowire system serviceable, letting integrators restore worn or damaged mounting and connection hardware without re-pulling the entire sensor cable.

Compliance

• For use within UL 521 listed Protectowire linear heat detection systems
• Supports installations designed to FM 3210 approval requirements
• Intended for application under NFPA 72 design and inspection practices

Key features

• Replacement hardware for an existing Protectowire LHD installation
• Supports secure mounting and routing of the heat-sensing cable
• Maintains circuit integrity at termination and support points
• Restores worn or damaged accessory hardware in service
• Helps protect connection points from mechanical strain
• Suited to industrial runs across long or distributed hazards

Protectowire LHD covers hazards where the sensor cable is routed continuously over distance, including tunnels, conveyor systems, warehouse storage racks, and cable trays. Accessory hardware such as the SG-42SK2 keeps that cable properly supported and terminated so the detection circuit performs reliably across its full length.
