Part No. 9159054 – Induction loop amplifier without 2N IP intercom accessory, Part
No. 9159051 – External induction loop for wall mounting, Part No. 9159052 - 12 V DC
power adapter) is part of sound system installations for hearing impaired persons that
are equipped with a special hearing aid capable of receiving reproduced sound via a
magnetic field receiver. The system is defined by the IEC 60118-4 standard.
Installation:
The induction loop amplifier can be wall mounted with the use of an internal induction
loop where a signal covering is requested. Outdoor use is possible thanks to the IP65
covering. A four-wire cable of the length of one meter is mounted to the supplied
product for easier connection to the intercom. In the cable are two wires for 12 V DC
supply and two wires for signal input, the wires are connected into interconnection
connector. If you shorten the cable, follow the colour marking.
Before wall mounting run the cable through the hole that you have prepared. Then
mark two mounting holes on the wall, through the amplifier front. Remove the
amplifier and drill the mounting holes. Use the plugs and screws included in the
delivery. Use a drill of the diameter of 6 mm. After fastening, cover the screws with
the blanks supplied.
Use the supplied connectors to connect the amplifier to the intercom and power
supply. The A connector is connected to the amplifier four-wire cable. Insert a special
intercom-connecting cable supplied with the amplifier and 12 V power supply outlets
to the B connector. Connect the special cable to the intercom and connect the power
supply to the mains. You can place the mated A and B connectors into the 2N IP
cover. The connectors help you connect stripped cables. Open the
intercom
connector by pushing a thin screwdriver onto the white spots at its front and close the
connector by sliding the movable part through a side gap.
Finally, test the amplifier function using a suitable receiver for hearing impaired
persons or magnetic field communication tester. No other settings are required.
