WS-15ZBS Water Leak Sensor
Introduction
WS-15ZBS is a ZigBee Water Leak Sensor. It is capable of sending wireless signals to the coordinator in
the ZigBee network upon water detection. The Water Sensor can be mounted on the wall using the
extension probe, or placed on the ground to use the probe on the back to detect water leakage or flood
condition.
The Water Sensor utilizes ZigBee technology for wireless signal transmission. ZigBee is a wireless
communication protocol that is reliable and has low power consumption and high transmission efficiency.
Based on IEEE802.15.4 standard, ZigBee allows a large amount of devices to be included in a network
and coordinated for data exchange and signal transmission
The Water Sensor serves as an end device in the ZigBee network. It can be included in the ZigBee
network to transmit signal upon activation, but cannot permit any other ZigBee device to join the network
through the Water Sensor.

Features
 Water Detection
The Water Sensor will be activated when water is detected by the probes. After activation, the
Water Sensor will transmit signal to the ZigBee network coordinator and raise alarm with its built
in buzzer for 10 seconds.
The Water Sensor will check if water is present every 10 seconds, if water persists after 10
seconds, the buzzer will continue to sound alarm.
If water persists, the Water Sensor will continue to send the alarm signal every 10 minutes.
If water is subsided, the Water Sensor will stop alarming and transmit a restore signal
 Alarm Silence
When the Water Sensor is alarming, press the Function button once on Water Sensor to enter
Alarm Silence mode for 10 minutes
Under Alarm Silence mode, the Water Sensor will not sound alarm. The LED Indicator will flash

2
every second to indicate it is under Alarm Silence mode.
After 10 minutes, if water still persists, the Water Sensor will raise alarm and send alarm signal
again.
 Battery and Low Battery Detection
The Water Sensor uses 1 CR123A 3V Lithium battery as its power source. The battery is
included in the package.
The Water Sensor features Low Battery Detection function. When the battery voltage is low, the
Water Sensor will transmit Low Battery signal to the coordinator in ZigBee network.
When changing batteries, after removing the old battery, press the Function Button twice to fully
discharge before inserting a new battery.
Supervision
The Water Sensor will transmit a supervision signal to report its condition regularly according to
user setting. The factory default interval is 30 minutes. The user can also press the Function
Button once to transmit a supervision signal manually.
ZigBee Network Setup
 ZigBee Device Guideline
ZigBee is a wireless communication protocol that is reliable, has low power consumption and high
transmission efficiency. Based on IEEE802.15.4 standard, ZigBee allows a large amount of devices
to be included in a network and coordinated for data exchange and signal transmission.
Due to the fundamental structure of ZigBee network, ZigBee device will actively seek and join
network after powering on. Since performing a task in connecting network may consume some
power, it is required to follow the instructions to avoid draining battery of a ZigBee device
- Ensure your ZigBee network router or coordinator is powered on before inserting battery into the
ZigBee device.
- Ensure the ZigBee network router or coordinator is powered on and within range while a ZigBee
device is in use.
- Do not remove a ZigBee device from the ZigBee network router or coordinator without removing
the battery from a ZigBee device.
 Joining the ZigBee Network
As a ZigBee device, the Water Sensor needs to join a ZigBee network to transmit signal when high
water level is detected. Please follow the steps below to join the Water Sensor into the ZigBee
network.
The Water Sensor can only join ZigBee network within 3 minutes after power on.
1. Insert the battery into the battery compartment to power on the Water Sensor.
2. Within 3 minutes after powering up, press and hold the Function button for 10 seconds, then
release it to join the network. Please make sure the permit-join feature on the router or
coordinator of your ZigBee network is enabled.
3. After joining the ZigBee network, the Water Sensor will be registered in the security system in
the network automatically. Please check the security system control panel or CIE (Control and
Indicating Equipment) to confirm if joining and registration is successful.
4. After joining the ZigBee network, if the Water Sensor loses connection to current ZigBee
network, the LED indicator will flash every 20 minutes. Please check the ZigBee network
condition and Water Sensor signal range to correct the situation
Factory Reset
If the Water Sensor did not successfully join a ZigBee network upon power up, or if you want to
remove the Water Sensor from current network and join a new network, you need to use the Factory
Reset function to clear the Water Sensor’s stored setting and information first before it can join
another network. To perform Factory Reset:
1. The Water Sensor can only be reset within 3 minutes after power up. If the Water Sensor has
been powered up for more than 3 minutes, remove and reinsert the battery.
2. Press and hold the Function button for 10 seconds, release the button until the Water Sensor
emits one long beep.
3. The Water Sensor has been reset to factory default setting with all its previous network
information removed. It will now actively search for available ZigBee network again and join the
network automatically.
4. If the Water Sensor successfully joins a ZigBee network, the LED Indicator will flash twice to
indicate.

Installation
 Mounting
The Water Sensor can be deployed on the ground or mounted on the wall
Ground Deployment
When deployed on the ground, the Water Sensor detects water through the probes protruding from its
back cover.
1. (If extension probe is connected) Open the cover by removing the bottom fixing screw on the
Water Sensor.
2. Remove the extension probe from the terminal.
3. Replace the cover.
4. Put the Water Sensor on the ground with the back cover facing downward.
Wall Mounting:
For wall mounting, the Water Sensor must be connected to the external extension probe, then
installed at desired height.
1. Remove the fixing screw and cover assembly.
2. Use a Philip screw driver to turn counter-clockwise and loosen the 2 screws on the extension
probe terminal. (Figure 1)
3. Insert the extension probe into the terminal, use the Philip screw driver to turn clockwise and
tighten and screws to secure the probe. (Figure 2)
Figure 1 Figure 2
4. Break through the wall mounting knockouts on the base.
5. Using the holes as a template, drill holes in the surface.
6. Insert the wall plugs if fixing it into plaster or brick.
7. Screw the base into the wall plugs.
8. Screw the cover back onto its base.
9. Find the plastic clip included in the package, insert the extension probe in the clip.
To use the plastic clip:
- Remove the double-side adhesive tape at the back of the clip and apply it to desired
location on the wall.
- Open the clip as in (Figure 3.) by using your thumbs.
- Once clip is opened, insert the water probe and secure the probe’s sensor head, make sure
the sensing probes are touched on the ground for water detection, then close the clip
(Figure 4).
Figure 3. Figure 4.

 Water Detection Probe
The Water Sensor is shipped with a factory supplied water detection probe. The probe may be further
extended by connecting other optional probes to improve detection rage.
Available option probe types include
A. 1 to 1 19cm probe.
B. 1 to 4 33cm probe.
C. 1 to 1 180 cm probe.
Multiple extension probes can be further interconnected according to user need. See pictures below for
some wiring samples.
 Using Water Sensor with ZigBee Router
IMPORTANT NOTE
If Water Sensor installation location is away from your system control panel and requires ZigBee
routers to improve signal strength. DO NOT use a ZigBee Router without backup battery. A ZigBee
router without battery will be powered down during AC power failure and the Water Sensor
connected to the router will lose connection with ZigBee network. You should plan your Water
Sensor installation location using only ZigBee router with backup battery.
