Yes. Protectowire linear heat detectors are resistive normally open contact devices that are compatible with most manufacturers’ control panels. The system designer should confirm Protectowire Linear Heat Detector compatibility with the panel manufacturer. Maximum zone lengths are determined by the resistance of the conductors. Protectowire Control Panels and interface modules are specifically designed and approved for use with Protectowire Linear Heat Detectors and are recommended to ensure compatibility and provide sole source system responsibility.
