Review the confirmed product information, including description, features, benefits, and applications.
The WFDNFT Waterflow Detector from Safe Signal is designed for primary signalling in systems using CPVC fittings. Its NEMA 4 rated enclosure is more damage-resistant than traditional metal designs and suits indoor and outdoor use.
The detector operates across a temperature range of 32°F to 150°F and provides high repeatability and resistance to vibration. An NPT threaded adapter fits 1", 1¼", 1½" and 2" metal tees and 1" and 1½" CPVC tees.
Enclosure & Environment
- UL-listed and NEMA 4 / IP54 rated.
- Lightweight, corrosion-resistant, unpainted plastic cover that acts as an insulator against shock hazard and arcing.
- Operating temperature range: 32°F to 150°F.
Switching
- Dual SPDT (Form C) synchronized switches in a durable terminal block.
- Switch synchronization activates alarm panel and local bell/horn strobe.
- Visual and audible (73 dBA) switch activation.
- Accommodates up to 12 AWG wire with wire-ready terminals.
Service & Security
- Sealed retard mechanism resistant to dust and contaminants.
