Industrial-grade sensing in a consumer-friendly form. The Honeywell RWD21 uses a cable sensor that you can extend up to 100 feet to monitor large areas — wrap it around water heaters, lay it along basement walls, coil it in sump pits. The 85dB alarm triggers the moment any point of the cable touches water. Works as a standalone alarm or integrates with Honeywell Total Connect 2.0 smart home systems.
