Smart Leak Detector, 1 Pack

Remote sensing disc

For water alerts near an accessible sink, washing machine or water heater, with a remote sensing disc that can reach a low point.

Consider before choosing

  • The detector alone does not physically close the water supply.
  • Remote alerts depend on successful setup/connectivity; local placement must intercept water.

Key manufacturer facts

  • Standalone detector monitors water, room temperature and humidity, with notification preferences in the Moen Smart Water system. Manufacturer source
  • The one-pack specification includes a CR123A battery and 48 in remote sensing disc. Manufacturer source
  • Optional 920-006 sensing cable is separate; the specification permits up to three linked cables. Manufacturer source

Use the included disc to reach the collection point

The 920-004 one-pack specification includes a 48-inch remote sensing disc. That can help place a sensing point away from the main detector where water is expected to collect. It is different from a cable that senses along its full length: choose the placement for the actual path of water.

Distinguish included and optional parts

A CR123A battery and the remote disc are listed with this model. The 920-006 sensing cable is a separate accessory; Moen’s specification allows up to three linked cables. Do not assume a one-pack detector listing includes that cable or that every multi-pack has the same contents.

Plan what happens after the notification

The detector monitors water, temperature and humidity through the Moen Smart Water system. Remote alerts depend on setup and connectivity, and the detector alone does not close the water supply. Keep a practical response plan and access for maintenance; compare Kidde if direct placement suits the space better than a remote disc.
