Product Description

SigNET’s new FPROK Fosmeter Pro Induction Loop Test Kit is designed to simplify the setup of an induction loop system and ensure its compliance with the latest version of BS EN 60118-4 (Magnetic field strength in audio-frequency induction loops for hearing aid purposes).

The kit includes the FPRO Fosmeter Pro induction loop tester, an MP3 player c/w pre-loaded test tones and a set of headphones.

The Fosmeter Pro is a 400mA magnetic field strength meter and loop listener, complete with circuitry for measuring background noise, frequency response and metal compensation.

It includes:
• A digital LCD display with a user-friendly interface to simplify testing
• Two ‘soft’ buttons which dynamically change their functions to suit the menu options being accessed
• Battery low indication and an auto-power off function that kicks in after 10 minutes of Fosmeter inactivity
• A 3.5mm headphone jack socket allowing users to listen to the loop signal using a set of HEAD1 headphones (supplied in FPROK kit)

The unit is powered from a 9v PP3 battery (provided) and is supplied in a protective canvas carrying case.

One FPROK Kit (plus ancillaries such as MP3 player/amplifier connection leads) is all it takes to ensure your loop installations comply with current British Standards.

Test Menus:
The Fosmeter Pro’s test results are typically shown on its LCD as shown right. A summary of these tests appears below:
Field Strength Test: Detects a pulsed 1kHz signal in accordance with BS EN 60118-4, calibrated at 400mA/m = 0dB L.
• Background Noise Test: Advises if the signal is acceptable, tolerable or too high in accordance with BS EN 60118-4.
Frequency Response Test: Detects 100Hz, 1kHz and 5kHz in
accordance with BS EN 60118-4. All three frequency readings are
displayed on the same screen allowing you tell at a glance if the setup is within the +/- 3dB L required by the standard.
Metal Compensation Test: This test goes beyond the scope of
BS EN 60118-4 but adheres to the 3rd octave frequency spectrum
advised in the standard, measuring 1kHz through 8kHz. For use with amplifiers with metal compensation controls/functions such as the PDA200/2, 500/2 & 1000/2.
Subjective Listening Test: This test is designed to ensure hearing aid users receive an undistorted and clear signal in the covered area and is performed using a set of headphones (supplied) plugged into the unit’s headphone socket.

BS EN60118-4 (2006)

What are Induction Loops?
Induction loop systems help hearing-impaired individuals with a hearing aid or loop listener to hear sounds more clearly by reducing or cutting out background noise. The induction loop is a cable that circles the listening area.

The loop is fed by current from a loop amplifier which takes its signal from a microphone placed in front of the person speaking or by means of a direct connection from another sound source, such as a sound system. The resulting electric current in the loop produces a magnetic field, which corresponds to the sound.

The hearing-impaired user can pick up this magnetic field within the area of the loop as long as their hearing aid - or loop listening aid - is switched to 'T'. The user can adjust the hearing aid for volume. More than one person can benefit from a loop installed in a room as long as they each have a hearing aid set to 'T', or a loop listener. One benefit of this set-up is the user is not wired to any other equipment and you are therefore free to listen from anywhere within the loop as well as able to move around.
