Easy Placement
The 3-Series Water Leak 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

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 Leak Sensor.
ZigBee Home Automation 1.2 Compatibility
The 3-Series Water Leak Sensor is fully ZigBee HA 1.2
certied and is guaranteed to function with all open,
ZigBee HA 1.2-certied hubs and devices.

The Water Leak 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.
