Induction loop supply and installation
It is important that you 'The Customer' fully understand the technical limits and problems the Audio Frequency Induction Loop System technology can cause. It is therefore important that the following terms and conditions set out are adhered to:

Optimal Information
It is essential that you 'The Customer' inform us of the activities that will take place in the specified room where the loop system will be installed and also the activities that may take place in adjacent rooms (as this may affect the loop system).

Magnetic Background Noise Interference
All electrical appliances and installations generate some form of magnetic field. If the field that is generated is strong enough it may cause the hearing aid user to experience some interference, which will render the loop system ineffective. In the event that the Ambient Magnetic Interference is found to be greater than 20dB we will advise that the installation will not go ahead, for which you will be charged accordingly.

Magnetic Overspill
It should be noted that by installing a loop system we are creating a magnetic field. It is possible that this magnetic field can overspill or cause interference into other rooms both next to, adjacent to, above or below the room that the loop system is installed in. This may give cause for concern in the following areas:

• Confidentiality: Conversations may be heard in rooms that are next to, adjacent to, above or below the room that has the loop installed, through the use of the T switch facility.

• Interference: This may cause a problem with other electrical equipment within the room i.e. computer monitor screens, internal telephone systems, electronic music instruments and existing PA systems.

Magnetic Soak Up
With this particular type of technology, the sound quality of a loop system can be influenced by metal work. For example: reinforced concrete, suspended ceiling grids, steel frame construction, and air conditioning metal ducts etc. If we are unable to carry out a survey of soak up during pre installation and we discover the magnetic soak up restricts the magnetic field strength to below +6dB + 3dB we shall advise that the installation should not go ahead and you will be charged accordingly.

Further Options
In the event of a non compliance with the above there are further options that can be considered. These options consist of the 'Super Loop', FM system or the 'Infra-Red' system.

Survey and Measurement Check Disclaimer
Should you 'The Customer' not adhere to the terms and conditions that are set out, leading to the absence of being able to carry out the above test, we cannot be held responsible for the final outcome.

Acceptance of an Estimate
Should you go ahead and accept the estimate, an official order is required. Verbal orders are not acceptable.

VAT Note
The proposed works are solely for those who have a hearing disability and wear a hearing aid with the T switch facility. The VAT element can therefore be zero rated providing that the purchaser is a registered charity and completes a declaration form as supplied by us.
