Meet The All-New Water Sensor

Household appliances, dodgy rooves and frozen pipes cause plenty of water damage that’s costly to repair,especially
when you don’t know they’re happening, and the leak is left to wreak havoc.

This handy water sensor helps you nip those troublesome leaks in the bud, alerting you before a few drips turn into a
tidal wave. Mitigate water damage, save repair costs, and maybe even cut your insurance premiums!


Setting an Example In What Compact Design Really Is

The DCH-S162 includes a strobe light, siren, mute/reset button, an RJ11 interface and onboard Bluetooth, you’ll be pleasantly surprised how we managed to pack so much in. All while only occupying a single power socket!


Expandable Coverage

You can conveniently expand your coverage area by adding additional DCH-S163 sensors (sold separately or available with the DCH-S1621KT Water Sensor Kit).

The DCH-S163 Battery-Powered Long-Range Water Sensor Add-on operates on interference resistant Sub-GHz bands, empowering it to work in conjunction with the central hub, even from afar1.

Compact and water resistant, it can be slipped under common appliances and placed in areas of interest: the basement, garage or even your garden shed.

1 DCH-S163 needs to be used in conjunction with a central hub, with a distance of 1,500 ft. in an open area and 300 ft. indoors
