• Easy-to-install mounting plate for sensor.
• Easy compatibility with other manufacturers’
ZigBee HA 1.2 devices.
• Pull-to-pair joining process.
• Over-the-air rmware updates.

Use Cases
• Be alerted if an appliance or pipe is leaking or
burst.
• Ensure that A/C drain pans don’t overow.
Automatically shut off water supply to home in the
event of a leak.
If the 3-Series Water Sensor detects water, it can trigger
a whole-home water shut off valve to disconnect the
water supply. This protects your home against leak
and ood damage even when you’re away or unaware
that there’s a problem.
Ensure that A/C drain pans don’t overow.
With the included clip-on standoff/remote leads,
you can place the water sensor in areas that there
is standing water. A/C drain pans contain some
Special Features
Easy Placement
The 3-Series Water Sensor can be placed on any
non-conductive surface. It’s as simple as joining and
placing it in a low-spot or near an appliance such as a
washing machine, refrigerator, or water heater.
Pull-to-Pair Join Process
All 3-Series sensors feature “pull-to-pair” joining. The
device ships with the battery pre-installed and all that
is needed to begin the joining process is to pull out
a small plastic tab from the bottom of the device.
There is nothing for the user to take apart or put back
together.

event of a leak.
• Prevent basements from ooding if a sump pump
fails.
water under typical operating conditions but with the
3-Series Water Sensor, you can be notied when the
water reaches an unacceptable level.
Prevent basements from ooding if a sump pump
fails.
Many homes with basements have water issues
requiring the use of an automatic sump pump to
remove water. When these pumps fail, the rising
water level can trigger notications with the 3-Series
Water Sensor.
ZigBee Home Automation 1.2 Compatibility
The 3-Series Water Sensor is fully ZigBee HA 1.2
certied and is guaranteed to function with all open,
ZigBee HA 1.2-certied hubs and devices.
Superior Range and Updatability
The 3-Series Water Sensor includes a built-in power
amplier, giving the module superior range and stability
in large homes or areas with wireless interference.
The Water Sensor also supports over-the-air updates
providing for seamless upgrades and feature additions
without the need for any user interaction.
Getting Started Troubleshooting
Step 1: Open ZigBee Network for Joining
Using your controller or hub’s interface, enable the
ZigBee network for joining.
Step 2: Pull Tab from Bottom of Sensor
Pull the small plastic tab out of the bottom of the
sensor and it will immediately begin searching for a
network to join.
Step 2: Finish Joining at Hub (optional)
Some hubs and controllers require additional steps
such as naming or categorizing the device.

Step 1: Remove and Replace Battery from Device
Remove cover from sensor. Remove battery and
replace with a new CR-2 battery. Reassemble and
test operation.
Step 2: Factory Reset and Rejoin
Remove cover from sensor and remove battery.
While holding down the reset button, reinsert battery
to factory reset the device. Repeat the “Getting
Started” steps to rejoin the ZigBee network.

Compatibility
The 3-Series Water Sensor features out-of-the-box compatibility with any ZigBee HA 1.2-certied hub, controller,
bridge, or platform.
