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.
