10. Functional system test

  • Updated

 

To ensure a fully operational system, all tests must be completed as described below by the installer before use. The system owner must then perform the test minimum twice per year to ensure a fully functional system.

NB! After the system has been tested, thorough training must be provided to the homeowner/user.

 

Simple valve test

  1. Press and hold the Linkbox+ button for 3 seconds
  2. Ensure the valve closes and water supply stops
  3. Press and hold the Linkbox+ button for 3 seconds
  4. Ensure the valve opens and water supply returns

Troubleshooting:

If the valve doesn't respond, check the connection of the Cat.6 cable, both in valve actuator and Linkbox+ (blue RJ45 connector). Also, check that Linkbox+ is powered via 230VAC (NB! Even though the 4G version of the Linkbox+ has a built-in backup battery, the Linkbox+ is not able to control the valve without 230VAC connected).

 

Testing Sensor Tape connected to Linkbox+

This test is only relevant if Sensor Tape is connected directly to Linkbox.

  1. Open a tap and let the water run (e.g. kitchen sink)
  2. With a wet cloth, moisten one of the sensor points on the Sensor Tape
  3. Ensure that:
    1. Valve closes
    2. Water stops running
    3. The Linkbox provides an audible alarm
    4. The linkbox waterdrop LED lights red
    5. A push notification in the Abralife mobile application appears (If app is used)
  4. Click the Linkbox+ button (< 1 second) to mute the alarm
  5. Carefully dry off the moistened sensor point
  6. Press and hold the linkbox+ button for 3 seconds to reset the system and open the valve
  7. Ensure that:
    1. Valve opens
    2. Water starts running
    3. The Linkbox waterdrop LED lights green
    4. A push notification in the Abralife mobile application appears

Troubleshooting:

-If the system does not go into alarm when the sensor tape gets wet, check that the sensor tape is correctly connected to the Linkbox+ (jack plug). Also check that there is no damage to the sensor tape.

-If the system goes into alarm when the sensor tape is moistened but the water remains open, see the section "simple valve test"

-If a tape extension or splitter is used and some of the sensor tapes do not trigger an alarm, check that the tape is correctly connected in the joints. If necessary, change the tapes to clarify whether it is the joint piece or the tape that is the problem

-If the valve does not open again after the test, there is most likely still moisture on the sensor tape. Wipe the tape with a dry cloth.

 

Testing Wireless Sensors

This test is only relevant if one or more wireless sensors are connected to the system

NB! Do not apply excessive water to the device when turned upside-down, as the IPx4 water ingress protection is only valid when the sensor is oriented with the probes facing down.

  1. Open a tap and let the water run (e.g. kitchen sink)
  2. With a wet cloth, moisten one of the sensor points on the sensor:
    1. If sensor is mounted in bracket with Sensor Tape, moisten one of the sensor points on the connected Sensor Tape.
    2. If sensor is mounted in bracket without Sensor Tape, moisten one of the two pairs of water detection probes on back of the bracket
    3. If no bracket/sensor tape is used, moisten one of the two pairs of water detection probes on back of the sensor (see picture below)

  3. Ensure that:
    1. Valve closes
    2. Water stops running
    3. The Linkbox provides an audible alarm
    4. The linkbox waterdrop LED lights red
    5. The affected sensor provides an audible alarm
    6. The affected sensor waterdrop LED lights red
    7. A push notification in the Abralife mobile application appears (if app is used)
  4. Click the Linkbox+ button (< 1 second) to mute the alarm
  5. Carefully dry off the moistened sensor point
  6. Press and hold the Linkbox+ button for 3 seconds to reset the system and open the valve
  7. Ensure that:
    1. Valve opens
    2. Water starts running
    3. The Linkbox and sensor audible alarms stop
    4. The Linkbox and sensor waterdrop LEDs light green
    5. A push notification in the Abralife mobile application appears 
  8. Repeat this test for each Watersensor+ installed

Troubleshooting:

-If the system does not go into alarm when a sensor gets wet, make sure that the sensor is powered. Check that the battery is correctly installed and that the protective plastic on the battery has been removed. If still no alarm, make sure the sensor is paired with the Linkbox+. (You can check this in the Abralife app). If the app is not used, try resetting the sensor by holding the button down for approx. 10 seconds until the drop symbol starts flashing white. Then re-pair the Linkbox+.

-If the system does not go into alarm and you have mounted the sensor in a bracket (with or without sensor tape), try testing the sensor without using a bracket. If the system then goes into alarm, check the bracket and any connected sensor tape.

 

Testing valve control with Abralife app (Optional)

The Abralife app can be used to remotely open and close the valve (assuming the Linkbox+ is online and added to a home). 

In the Overview section of the app, click the water leakage tile (a1) or the valve widget (b1). Click the valve button (a2 / b2) to close the valve. Ensure the valve and the water supply closes. Repeat to open the valve and restore the water supply.

Troubleshooting:

-If the valve does not close when you click on the valve button in the app, check that Linkbox+ and the mobile phone are connected to the internet. Also check that you have selected the correct home in the app (at the top of the "overview")
