  • Page 2 Low Power Inductive Loop – ILO1 for Phone Line only The standard speaker box, as used with a Windcrest Autodialler, can accommodate a low power inductive amplifier which amplifies the sound on the BT phone line.
  • Page 4 Medium Power Inductive Loop – ILO7 for Phone line and Speech Synthesis unit For applications where a greater coverage is required and where a speech synthesis unit is installed, the IL07 solution is offered. This unit is mains powered with battery back up and a higher current drive capability.

  • Page 6 Testing the Inductive Loop system As mentioned, the inductive loop amplifiers produce the magnetic field which corresponds to the sound. The ILO7 system has a facility to adjust volume in case distortion is encountered in the speech. Adjust the volume so that the LED on the board just starts flickering when speech is on.
  • Page 7 Various test units are available which provided a means of testing the effectiveness of the loop. Audio Pick up Unit A test unit which acts like a hearing aid and simply coverts the magnetic field into sound which is played through a pair of headphones.
  • Page 8 Prior to the dispatch of Inductive loops, each loop is tested with the Audio pick up Unit in the factory with a preinstalled loop cable. Each system is check for the strength/range. The low power inductive loop i.e. ILO1 covers a distance of approx. 300mm from the Windcrest ILO1 Speaker box. The high power inductive loop i.e.
