Installation

The KEY-2.7 chassis mounts directly to the wall
surface. The following steps outline the installation
procedure:

• Cut out the required mounting hole in the wall
above the flush-box.

•Terminate a RJ45 plug to the CAT5E cable
wiring instructions on page 9.

• Connect the RJ45 plug to the KEY-2.7.

• Secure the keypad in position using the supplied
flush-box screws.

• Program the keypad (see page 11).

• Select the required Source Key Cap’s, and
secure in position using the Key Cap Bracket.

• Push the keypad cover plate into position.

CAT5E cable terminated with a RJ45 plug is used to connect to the KEY-2.7.
Use the standard 568-B color code for the CAT5E termination:

Pin # Wire Color Keypad function

1 White/Orange +12V DC supply

2Orange 0V supply

3 White/Green IR output

4 Blue nc

5 White/Blue Data input

6 Green 0V supply

7 White/Brown nc

8 Brown nc

When cabling use CAT5E home runs with a maximum length of 200m.
“Daisy chaining” or parallel connection of up to four keypads per CAT5E cable may be used.

System Wiring —

Continued

Connecting to an Integra Multi-Zone amplifier MZA-4.7

KEY-2.7 keypads are wired to the
MZA-4.7 Interface port.
Integra controllers - keypad’s ­may be parallel connected.
IR emitters plug into the IR outputs
and are fixed to the source equip­ment’s IR windows.

Note: Ports IR1 and IR2 are Inter-

face port specific, while ports
IR1+IR2 relay the signals from
both interface ports.

Troubleshooting

Specifications

No control at all.

– The KEY-2.7 forms just one part of an IR

system. There are potential issues with
connections, wiring, power supply, IR
receiver and emitter placement, plus
other optical and EM interference and
ground loop possibilities.

– It is best to strip the IR system back to just

one controller and debug from there.

–With no IR activity the IR terminal

should read 0V - if not then check all wir­ing and connections, ensure the keypad
programming is correct, and the keypad is
functioning correctly.

Keypad does not track the MZA-4.7.

– Ensure the data termination has integrity,

and is not shorted to other conductors in
the CAT5E. Ensure the keypad is cor­rectly zoned.
