When considering the installation of a hearing loop, there are 3 main steps that need to be considered.
Planning, Installation and Measurement. These are vital in a successful loop installation.
Initial Planning
It is important to plan for successful installations. This ensures that all aspects have been considered. You need to:
- Find out the purpose of the room
- Consider the size of the room to be covered.
- Decide whether an induction loop is the correct solution.
- Select a loop amplifier with the sufficient power output.
- Investigate how much metal is present and how it will affect the loop.
- Decide if overspill needs to be controlled.
- Choose which loop system is best suited for this project.
Installation
Factors to consider include:
- Loop wire or Copper tape
Where the loop is to be fitted – ceiling, floor or wall - What material is the ceiling, floor or walls
- The influence of other systems within the building ie. projectors, white boards etc
- Where to put the amplifier.
Measurement
A loop system cannot be finalised and approved until the installer has certified it. The following points are important:
- A system must be measured and certified according to the IEC standard 60118-4
- The measurement can only be performed by a true RMS field strength meter such as the UniVox FSM 2.0
Installation Tips
- Choose an amplifier that gives at least 20% margin to compensate for the metal loss
- If you have a square loop, the sides should not exceed 10m
