Induction Loop internal
The 2N
®
IP Force Induction Loop (Part No. 9151021) is one of the 2N
®
IP
Force extending modules, used for people with disabled hearing equipped
with a special hearing aid that receives reproduced sound via a magnetic
field sensor.
Mounting guide:
Switch off the intercom.
Remove the front panel (7) from the intercom.
Mount antenna board (8). Use two enclosed self tapping screws (9).
Plug enclosed cable (11) to the antenna board connector.
Demount a button PCB (1). Don't disconnect its cable!
There will stay four spacers after the switch board removal. Dismount the bottom right one.
There are two short metal spacers enclosed to the reader. Take a longer one (5), 12 mm long. Screw it into
the free hole.
Plug an enclosed plastic support (6) to the reader board from the bottom side.
Put the reader board (4) in the main board connector making sure that the mounting hole is directly above
the spacer.
Screw in a remaining metal spacer (3), 10.5 mm long.
Fit the button PCB (1) back to its position using original bolts (2).
If you want to use the tamper switch (to detect unauthorized opening the case, as a theft protection), insert
the tamper board (10) in the connector located in the right-hand bottom part of the reader board (4). As the
tamper switch shares the relay output (NO and NC) terminals, you cannot use the RELAY2 output with the
tamper switch at the same time.
Plug the antenna cable (11) to its connector at the reader board (4).
Place front panel back and tighten all four screws.
