Incognito LM10 3
Thank you for purchasing this Cambridge
Audio Incognito product. The LM10 Local
Input Module is an in-wall module that
allows the user to add an additional local
source to those distributed by the AH10.
The local source may only be heard in the room
where it is connected and the corresponding
sub-zone (if connected) and is not distributed
to other rooms. LM10s can be fitted in as many
rooms as are desired. The LM10 connects
between the audio hub and a KP10 amplified
control module using Cat-5/5e wiring.
Each main zone can support two LM10s, giving
you the option of listening to one or two local
sources (eg. Playstation, MP3 player). Each
local source can be controlled through the
Incognito remote and/or keypad (see instruc-
tions on entering local source rotate mode on
page 15). The LM10 can also support sub-
zones (where fitted) so that the local source is
audible in both main and subzone areas.
Now we invite you to sit back, relax and enjoy !

MOUNTING THE LM10
Locate the LM10 near the local source. Check all connections and test the system’s operation
before installing the LM10 into the wall. Using the included hardware, install the LM10 into a
standard electricians back-box (pattress) (LM10-EU=UK47mm depth single gang, LM10-CU=USA-
type J-box 50mm).
Important
Care should be taken in choosing a site for the LM10, ALWAYS refer to the precautions later in
this guide. Bear in mind that any local sources will likely require mains power.
The LM10 must never be installed in a back-box (pattress) which also contains mains wiring.
The recommended maximum length for use with standard Cat-5 cable is 30m from hub to LM10
to keypad in total. Screened Cat-5 can also be used.
FITTING THE LM10
Note: The LM10 is powered via the Cat-5 cable and no mains connection is required.
The procedure for fitting is as follows:
Remove the supplied faceplate from the LM10 by gently prising apart. It will ‘pop’ off.
Connect each wire in the Cat-5 cable to its respective terminal in the punch-down connector on
the back of the LM10.
Be very careful to follow the colour-code that is indicated on the connector. Always double-check
your connections, and your punching.
Fit the LM10 to the back-box (pattress) that you have fitted in your wall. This is done with the two
supplied screws (LM10-EU=M 3.5mm x 20, LM10-CU=6 x 32 pitch UNC x 6mm Countersunk).
Gently push the faceplate back on to the module.

SAFETY PRECAUTIONS
Avoid placing the LM10 near to dimmer switches or other items, which generate a lot of
electrical noise. Avoid fitting the LM10 in areas of high humidity.
The LM10 runs on 24V DC supplied through the connecting cable. As such there is no mains volt-
age present in the LM10 and the unit is often safe to fit in areas where only extra low voltage
(ELV) equipment is permitted. However, it is imperative that you always check the wiring regula-
tions in force for your application and area.
FACEPLATES
The LM10 faceplate system is based on the (LM10-EU=50x50 ‘easy-clip’ module, LM10-
CU=DecoraTM) standard and is interchangeable for the wide range of faceplates made by manu-
facturers such as (LM10-EU=MK Electric, RPP etc, LM10-CU=Leviton etc) that conform to this
standard. If it is desired to fit another faceplate, it can be replaced by gently prising apart the
LM10 faceplate and snapping on another in its place.

CAT-5 CONNECTIONS
A Cat-5 cable is used to connect the LM10 to a keypad output on an AH10 hub and to a KP10
amplified control module. Use Cat-5 cables (use EIA/TIA 568A RJ-45 wire configuration, see page
7) to connect from the hub to a LM10 wall plate (optional), and then wire from the wall plate to
the KP10 (see opposite diagrams). The LM10 has punchdown connectors for the eight individual
conductors of the Cat-5 cable, use a punchdown tool (LM10-EU=Krone, LM10-CU=110+ blade)
to insert conductors. If using shielded Cat-5 cable, connect the shields to the green terminal
blocks as shown in the opposite diagrams (dotted lines).
Note: When wiring directly to the LM10, crimp on a male RJ-45 connector using the EIA/TIA 568A
RJ-45 wire configuration (see Wiring Guide: EIA/TIA 568A wiring standard on page 7) for connec-
tion to the hub.
Single local audio source
Connect the LM10 as shown in the diagrams. Switch over SW1 (LC1) to the ON position and SW2
(LC2) to the OFF position. The LM10 will respond to the Local 1 remote command when selected.

10 Incognito LM10
It is possible to add up to two LM10 units per main zone. This gives you the option to listen to
either one by selection from the keypad or LR10 remote control (Local1/Local 2). The module
needs to be told whether there are one or two LM10’s present.
Dual LM10s fitted in a single zone
Connect the LM10s as shown in the opposite diagrams.
Local Source 1 – Switch over SW1 (LC1) to the ON position and SW2 (LC2) to the OFF position.
Local Source 2 – Switch over SW1 (LC1) to the OFF position and SW2 (LC2) to the ON position.
Note: If using an LR10 to select the local source, this will ONLY select Local 1 as default.
