2. Opening the sensor

1. Twist the flood sensor case counterclockwise and

remove it to access the battery compartment.

Remove the battery pull tab to power the sensor

WARNING: the flood-detection
prongs on the underside are
pointed by design. When
opening the sensor, twist the
case by its smooth edges to
to avoid contact with the base and
the sharp prongs.

2. Remove the Battery pull tab

NOTE:

When powered, the device will indicate Z-Wave status with LED:

1. Blink slowly for 3s: the device is not added to any Z-Wave network.

2. Solid for 3s: the device is already added to the Z-Wave network.

3. Add the device (see "Adding/removing the device" on page 6)

4. Close the cover and turn it clockwise.

5. Place the sensor on a surface prone to flooding,

or use the extension probe (see "Installation")

WARNING: the flood-detection prongs on the
underside are pointed by design. When opening the
sensor, twist the case by its smooth edges to avoid
contact with the base and the sharp prongs.

3. Installation

The Ezlo Z-Wave Flood Sensor should not be
mounted directly on or near metal framing or other
large metallic objects since metal objects may
weaken the radio signal strength.

After “activation” process, the sensor can work
without any installation. Further more, you can use
the extension probe to fix sensor body.

To install with extension probe,

follow the steps:

3.1 There are 3 kinds of methods to install the base

plate of extension probe into the wall.

3.2 Magnet the sensor body (note the direction)

3.3 Paste the extension probe close to the area

where can detect water or leaks.

4. Pairing the Ezlo Z-Wave Flood

Sensor to your Ezlo Z-Wave Hub

(See chapter 5 for pairing with other Z-Wave compatible hubs)

4.1 Pairing:

1. Open the cover of the sensor

2. Place the device within the direct range
of your Ezlo Z-Wave Hub.

3. Open the MiOS app and press on "More"

4. Tap on "Devices", then press on "+" in
the top right corner.

5.  Select your Ezlo Z-Wave Hub from the
Controllers list.

6. Choose or search for Ezlo Z-Wave Flood
Sensor from the list and press "Next".

7. The Ezlo Z-Wave Hub is now waiting for
you to make the Adding/Removing 
procedure from the Sensor side.

8. Triple-click the Z-Wave Pairing Button
quickly; the LED indicator should blink
fast in blue

9. Wait for the pairing process to end.

10. Successful pairing will be confirmed by
the Z-Wave Hub's message.

4.2 Unpairing

1. Open the cover

2. Place the device within the direct range of your Z-Wave hub.

3. Set the main controller remove mode (see the controller's manual).

4. Tap the Z-Wave button three times quickly. The LED indicator will turn solid blue to for two seconds if the sensor is removed successfully.

5. Wait for the unpairing process to end.

6. Successful pairing will be confirmed by the Z-Wave hub’s message.

5. Including the Ezlo Z-Wave
Flood Sensor to other Z-Wave
compatible hubs

5.1 Pairing

1. Open the cover.

2. Place the device within the direct range of your Z-Wave hub.

3. Set the main controller's adding mode (see the controller's manual).

4. Tap the Z-Wave button three times quickly. The LED indicator will blink blue to signal communication and turn solid blue for two seconds if the sensor is added successfully.

5. Wait for the pairing process to end.

6. Successful pairing will be confirmed by the Z-Wave controller's message

5.2 Unpairing

1. Open the cover

2. Place the device within the direct range of your
Z-Wave controller.

3. Set the main controller remove mode(see the
controller's manual).

4. Triple click the Z-Wave pairing button quickly,
the LED indicator should blink fast in orange.

5. Wait for the removing process to end.

6. Successful adding will be confirmed by the

Z-Wave controller's message

6. Resetting

The reset procedure clears the flood sensor's
memory, including Z-Wave network controller
information and advanced configuration.
To reset a Flood Sensor :Press and hold the
Z-button for more than 20 seconds.

NOTE: Use this procedure only in the event that
the network primary controller is missing or
otherwise inoperable

7. Associations

Association allows the flood sensor to control other
Z-Wave device such as Siren, Smart Switch, etc.

The Flood Sensor supports two association
groupings.

Group 1 reports the flooding detection, shock
detection and the battery level.

Group 2 is assigned to send BASIC SET command.

TIP:

1. The max number of associated nodes of each
group is 5.

2. Association allows for direct transmission of
control command between devices and takes
place without the participation of the main
controller

8. Wake Up

Wake up interval(Unit: seconds):
(1) When the device is included, short press Z-Wave
pairing button one time, after release, it will send a
Wake Up Notification

(2) Use the command “wake up interval set” to
configure the interval time of wake up. If the
configured time is less than 3600 seconds, the
device will not automatically wake up. The
minimum unit configured by the user is 3600
seconds.

(3) Wake Up Interval Capabilities Report CC
Minimum Wake Up Interval Seconds = 3600s
Maximum Wake Up Interval Seconds = 2678400s,
equal to 31days

Default Wake Up Interval Seconds = 3600s
Wake Up Interval Step Seconds = 3600s
