2N 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. 915905 – 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 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.
