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 there 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 color marking.
Before wall mounting the amplifier, run the cable through the hole that you have prepared. Indicate the position of the holes for installation, the two holes on the 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 device 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.
