Internal Induction Loop
The internal induction loop (Part No. 9151021, 02338-001) is one of the 2N IP Force extending modules, which is used for people with disabled hearing equipped with a special hearing aid that receives reproduced sound via a magnetic field sensor.
Compatibility
Caution
Where an internal induction loop is used, an RFID card reader cannot be inserted in the device.
If the additional and tamper switches are installed at the same time, no internal induction loop or RFID card reader can be installed in addition to them.
The module is compatible with the basic units with Part No.:
9151101RPW
9151101CHRPW
9151102CHRW
9151102RW
Installation

Turn off the device.
Remove the front panel (7) from the device.
Mount the antenna board (8). Use the two enclosed screws (9).
Plug the enclosed cable (11) to the antenna board connector.
Demount the button PCB (1). Do not disconnect its cable!
Dismount the right-hand bottom spacer (there are four spacers altogether).
There are two short plastic spacers enclosed to the induction loop. Take the shorter, 6,5 mm long spacer. Screw it into the free hole on the motherboard.
Plug the enclosed plastic support (6) into the reader board from the bottom side.
Put the reader board (4) in the motherboard connector. Make sure that the screw hole is directly above the spacer.
Screw in the remaining metal spacer (3), which is 10.5 mm long.
Fit the button PCB (1) back to its position using the original screws.
If you want to use the tamper switch (to detect unauthorized case opening for theft protection), insert the tamper board (10) in the connector located in the right-hand bottom part of the switch board (4). As the tamper switch shares the Relay2 NO and NC terminals, you cannot use the RELAY2 output and the tamper switch at the same time.
Plug the antenna cable (11) to its connector at the reader board (4).
Replace the front panel and tighten all the four screws.
