•
Full Coverage of North Penn High School Auditorium – Main Floor, under balcony, balcony.
•
Full Coverage of North Penn High School - Audion
•
Full Coverage of Educational Service Center – Conference Room A
The AFILS extent of supply shall incorporate all necessary components and works, including but not limited to the following:

A Certificate of Conformity to this standard shall be issued for each AFILS in the project.
In addition the system shall comply with:
•
2010 Americans with Disabilities Act (Section 706)
•
2012 International Building Code (Section 1108.2)
The Contractor shall:
•
At the earliest opportunity in the project, provide evidence that the background magnetic noise in the areas designated for loop coverage is within the limits defined in the standard, IEC 60118-
4:2006. Where the background magnetic noise exceeds -32dB re: 400mAm
-1
[-22dB for shortterm use/localised applications], the contractor shall not proceed without client approval.
•
Prior to installation, show that cross-talk between adjacent looped areas (whether part of this contract or not) will, by design, be less than -40dB with normal signal levels.
•
Prior to installation, provide evidence that the effect of metal within the structure of the building has been adequately assessed and compensated for by loop design and / or appropriate loop driver selection. Where necessary, the effect of metal shall be assessed by site survey and test using trial loops on relevant construction, carried out by a competent test specialist.
•
Prior to installation, provide calculations to demonstrate that the field strength of the proposed systems will meet the requirements of the standard IEC 60118-4:2006.

Audio inputs shall provide clear pick up of all wanted audio signals whilst minimising unwanted audio and background noise.
•
Signal-to-noise improvement is important to provide benefit to the hearing aid user
•
The input system design shall provide selective amplification of the intended audio signal above the general sound level in the area
•
Where a sound reinforcement system is installed, a line level feed from the system to the induction loop should be used where this is appropriate, which may include feeds from emergency evacuation systems.
•
A single boundary microphone mounted on the ceiling is unlikely to provide sufficient rejection of background acoustic noise in most rooms and should not be used unless it can be demonstrated that the system delivers tangible benefit to the hearing impaired.
•
Input levels shall not be adjustable at the signal source or connection point.
AFILS drivers shall be provided to amplify input audio signals and to drive the induction loops appropriately. The drivers shall meet the requirements for a type A or type B driver as defined below.
Where the horizontal loop area that must be covered is in excess of 6½ feet x 6½ feet, for either a onephase or two-phase (phased array) system:
Each induction loop driver shall have the following characteristics:
•
‘Current drive’ output
•
Rated current and voltage capable of driving the designed loop without clipping or distortion of the signal with full power bandwidth up to at least 1.6kHz
•
Capable of delivering the rated current and voltage into a load with 1kHz sinewave signal for at least 20 seconds continuously without damage to the unit or interruption of the output signal
•
Frequency response from 80Hz to 6.5kHz
•
THD+N less than 0.2% at 1kHz sine at full current
•
Automatic Gain Control (AGC) optimised for speech, with a dynamic range greater than 36dB
•
Metal loss correction with an adjustable gain slope range of at least 0dB to +3dB per octave
•
Input facilities of a type and connection suitable for the intended audio inputs to the system.
Where input connections are to exceed 10 feet in length, balanced inputs shall be available.
Balanced microphone inputs shall have phantom power available.
•

•
Adjustment of controls for commissioning shall be achievable without exposure of terminals carrying hazardous voltages
•
Unit must be rack mountable
•
All AC powered devices shall have passed testing at a Nationally Recognised Testing Laboratory
(NRTL) for safety with reference to the current edition of UL 60065 and any other applicable safety standards.
Where two-phase systems are required, a single unit shall be provided that is capable of driving two separate outputs with a 90° phase shift accurate to ±1° from 100Hz to 5kHz, or two identical drivers shall be provided unless it can be demonstrated in the system design that this is not appropriate. If two

identical drivers are appropriate, in addition to the requirements above, each driver shall have the following characteristics:
•
Slave input/output socket providing an insert point after the input AGC but before the output drive control
•
Auxiliary power outlet on rear panel with ±15V dc, 150mA minimum capacity
•
Front panel indicators to indicate separate fault conditions of overload, overheat and loop error
In a two-phase system, there shall be an independent 90° phase shift unit (to be provided) with the following characteristics:
•
Derives power from a loop driver dc power outlet
•
Obtains input signal from one loop driver slave output
•
Provides separate outputs to both driver slave inputs
•
Generates a constant 90° phase shift between the outputs.
•
Accuracy ±1° from 100Hz to 5kHz
Loops connected to the AFILS system shall meet the following requirements:
•
Be designed and implemented to meet all requirements of section 3 above.
•
The implementation of the loop design shall take into account the layout and fabric of the building
•
Appropriate materials for the installation location shall be used (e.g. wire in the floor/ceiling, flat copper tape under floor coverings, or a purpose-designed loop coil inside a counter vertical front)
•
Loop wire containment shall be of non-metallic construction (to avoid short circuit earth paths parallel with the loop wire). This restriction does not apply to the loop feed wiring between a loop amplifier and the start of the loop itself, which may be installed in metal or non-metal containment.
•
Where flat copper tape is accepted for use under carpet or other floor coverings, this does not require the use of containment and shall be installed according to the manufacturer’s recommendations and current best practice.
•
Implementation of the loops shall in general follow best practice
For each loop location a loop receiver shall be provided for operational staff to check and monitor the performance of the AFILS system. The receiver shall have the following characteristics:
•
Headphone output and be provided with headphones

•
Headphone output for listening to the loop signal
•
Instructions for setting up an AFILS to IEC 60118-4:2006 by use of the field strength meter
