Induction Loop (Part No. 9159050 – Induction loop amplifier for 2N IP intercom , Part
No. 9159054 – Induction loop amplifier without 2N IP intercom accessory, 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 intercom cover. The connectors help you connect
stripped cables. Open the 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.
