Key features

• Provides a supervised end-of-line termination for PHSC linear heat detection cable runs per NFPA 72 requirements
• FM Approved for use in loss prevention and property protection applications subject to FM Global data sheets
• Maintains cable circuit continuity supervision to detect open-circuit faults during normal system operation
• Compatible with the full range of Protectowire PHSC cable types and temperature ratings
• Installs using Protectowire-specified tooling to preserve UL and FM listing for the detection circuit

Protectowire PHSC-Series linear heat detection systems require properly terminated end-of-line connections to maintain supervisory circuit integrity per NFPA 72 and FM Global requirements. The WAW-N provides the end-of-line termination for the far end of a PHSC cable run, completing the supervised initiating device circuit that allows the fire alarm control panel to continuously monitor cable continuity. Loss of continuity triggers a trouble signal, isolating faults before they compromise detection coverage. The FM Approval supports applications in facilities governed by FM Global loss prevention standards.

Verify panel/device family compatibility before ordering.
