FCC ID: GX9WLS23F1919 Water Leak Sensor

Water Leak Sensor (WLS-23) Introduction WLS-23 is a Water Leak Sensor. It is capable of sending wireless signals to the Control Panel upon water detection. The Water Sensor can be placed on the ground, or mounted on the wall using the extension cable to detect water leakage or flood condition. The Water Sensing Cable and built-in water sensing probes can detect water leakage or flood condition. It can be placed on the ground, or mounted on the wall and further extended by connecting to another water sensing cable to improve detection range. Parts Identification 1. LED Indicator

- Continuous flash:

- Flashes twice:

the Control Panel.

- Flashes 3 times:

1) When the Water Sensor is transmitting a learning signal. 1) When the Water Sensor receives acknowledgement from 1) When the Learn/Test Button is pressed under normal operation mode, and the device will emit 1 beep;

2) When the Learn/Test Button is pressed under low battery status, and the device will emit 3 beeps;

3) When the Learn/Test button is pressed under normal operation mode or while alarming.

- Flashes 10 times:

1) When battery power is provided to the device;

2) When the Water Sensor is transmitting an alarm signal, and the device will beep continuously;

3) When the Water Sensor is transmitting a restore signal.

- Quick flashes every 4 seconds:

1) The battery is exhausted. 2. Buzzer 3. External Water Probe Connector 4. Battery Compartment

- The Water Leak Sensor is powered by one CR123 3V Lithium battery. 5. Mounting Hook 6. Learn/Test Button (inside the cover)

- Press and hold the button for 3 seconds to transmit a learning

- Press the LEARN button once to send a learning signal to the code. Control Panel

- Press once to send a supervisory signal to the Control Panel

- Press once while alarming to enter Alarm Silence Mode. 7. Built-in water sensing probes 8. Waterproof Case 9. Battery Insulator 10. Learn (characters imprinted on the back cover) 1 Features Water Detection The Water Sensor will be activated when water is detected through:

1. The external water sensing cable. Please remove the pre-installed plastic plug from the external water probe connector, the Water Sensor will emit beep sound every 10 seconds for 5 minutes to indicate absence of plastic plug, please connect the external water probe to the connector (Refer to Mounting for details). 2. The built-in water sensing probe. Please make sure the plastic plug is well inserted when using this type of detection function.

(Refer to Mounting for details). If water is detected for 1 minute through the above two detecting methods, the Water Sensor will start alarming and the Red LED will flash 12 times along with continuous beeps. The Water Sensor will transmit an alarm signal to the Control Panel. After 2 minutes, if water still persists, the Water Sensor will transmit another alarm signal to the Control Panel. If water is subsided for 1 minute, the Water Sensor will stop alarming and transmit a restore signal and the Red LED will flash 12 times. If water is detected again, the Water Sensor will be activated and raise alarm. Alarm Silence Press the Learn/Test Button once to enter Alarm Silence mode while alarming. Under Alarm Silence mode, the Water Sensor will not sound alarm and stop detecting water leakage. After a restore signal is transmitted to the Control Panel, if alarm warning condition is met again, the Water Sensor will raise alarm again. Battery and Low Battery Detection The Water Sensor uses one CR123 3V Lithium battery as its power source. The Water Sensor features Low Battery Detection function. When the Water Sensor is low on battery, a low battery signal will be transmitted along with regular signal transmissions. When the Learn/Test Button is pressed under low battery status, the Water Sensor will emit 3 beeps and the Red LED will flash 4 times to notify the user. The Low Battery signal will not disappear until a new battery is inserted. Please replace the battery as soon as possible. When the battery is exhausted, the Water Sensor will stop working and its Red LED quick flash every 4 seconds to notify the user. Please replace the battery as soon as possible. When changing battery, after removing the old battery, press the Learn/Test Button twice to fully discharge before inserting a new battery. Supervision The Water Sensor will transmit a supervision signal to report its condition every 15 to 18 minutes. The user can also press the Learn/Test Button once to transmit a supervision signal manually. Getting Started 12 times. Remove the battery insulator to power on the Water Sensor. After 1 minute, the Red LED will flash Put your Control Panel into learning mode (Please refer to your Control Panel manual for details). Press and hold the Learn/Test Button for 3 seconds to transmit a learn code to the Control Panel, the LED will flash continuously to indicate. If the Control Panel receives the learn code, it will display the information accordingly, refer to the Control Panel manual to complete the learning process. You can start Mounting process Installation Mounting

(Fig 1.) There are two ways to mount the Water Sensor:

Wall mounting (use the external water sensing probe):

1. Choose to install the Water Sensor at a desirable height 2. Drill hole in the surface. 3. Insert the screw into the hole. 4. Hook the Water Sensor onto the screw using the Mounting Hook behind the device. 5. The external water probe connector is pre-installed with a plastic plug (Fig.1), please remove it. 6. Connect the enclosed water sensing probe to the external water probe connector. Ground surface mounting (use the built-in water sensing probes):

- Simply place your Water Sensor at the desirable location on the ground.

- Do NOT place on conductive surface. 2 Water Sensing Cable A Water Sensing Cable or Water Probe Cable is available for selection. The cable can be further extended by connecting to another cable to improve detection range. Water Sensing Cable

(earphone jack type)

(used for WLS-23-S) Water Probe Cable

(earphone jack type) User Guidelines When water is detected through the Water Sensing Cable or Water Sensing Probe, the Water Sensor will start alarming and transmit an alarm signal to the Control Panel. Upon receiving an alert notification from the Control Panel, unplug the Water Sensing Cable. Use a towel to dry the Water Sensing Cable. It is recommended to air dry residual water in a ventilated place for at least two hours before inserting the sensing cable. 3

<NOTE>

Avoid direct or indirect sunshine. Improper storage can cause damage to the sensor and the cable. 4 Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
