The Floor Damage Sensor is an indispensable tool for installers and homeowners who prioritize maximum protection for their floor heating system. Its purpose is to provide advanced warning by immediately alerting you in the event of damage to the heating cable or mats. This proactive feature helps prevent potential costly repairs and eliminates the need for floor removal.

Installing the Floor Damage Sensor is a simple and straightforward process. Connect the heating mat cables to the back of the sensor, and it becomes a vigilant guardian for your heating system. Should the heating cable sustain any damage during installation or by a tiler, the sensor will emit a high-pitched alarm, promptly notifying you to take necessary action.

By utilizing the Floor Damage Sensor, you can ensure the longevity and functionality of your floor heating system. It provides peace of mind, knowing that you will be alerted to any potential issues before they escalate into larger and more expensive problems.

Thanks to its durable construction and reliable performance, the Floor Damage Sensor can be used repeatedly, offering ongoing protection for your investment for years to come.

It's important to note that the sensor requires 2 AA batteries for operation (batteries not included). Make sure to have these on hand to benefit from continuous monitoring and protection.

InstallationElement / Continuity Tester:

The following instructions are essential before commencing installation:

  1. Clip the Brown or Red wire of the element cold tail to L1 (red lead).
  2. Clip the Blue or Black wire of the element cold tail to L2 (Black lead).
  3. Clip both green wires of the element cold tail to the Green lead of the tester.
  4. Switch the tester on.
  5. A Red Light will indicate that the tester is on and working.
  6. If the tester emits a "Beeping" sound, it means there is a fault. If there is no "Beep," you can continue with the installation.
  7. If the beep sounds at any time before or during installation, STOP IMMEDIATELY, as it indicates damage to the element. You will need to contact an electrician for repair.
  8. Once you have finished the installation and before you start tiling, reconnect the tester as described above and turn it on.
  9. Keep the tester on until your tiling is complete.
  10. If the tester light turns off, you will need to replace the batteries.
