Overview
The Local MPI-2 rack unit is Lencore’s music and page interface (MPI) to be
used for iNET systems. The MPI-2 is capable of zoned or all-call paging as well
as background music. Paging can be made via any telephone on the network or
a microphone. The MPI-2 has the ability to page up to 99 individual zones for
paging using standard DTMF tones through a POTS appearance telephone line.
The system is also programmed for all-call and emergency broadcast paging.
Background music can be added from any line-level source. The Local MPI-2
rack unit also has the ability to play break tones, pre-recorded messages, and
doorbell chimes. The Local MPI-2 rack is designed to fit into a standard 19” rack.

MPI-2 Rack Unit
Lencore’s Music Page Interface (MPI) Rack Unit replaces all the bulky headend
equipment that that is associated with music and paging systems. With the MPI,
there is no need for additional cable home runs, amplifiers, separate equalizers,
special switching equipment or matching vendors for compatible product interfaces.
The MPI’s technology is so sophisticated that it can allow zone additions,
modifications, deletions and other changes to the paging system on the fly, without
rewiring. This eliminates the need for running multiple home runs back to the
electrical closet or through building risers to create separate or additional zones.
The MPI allows the ability to use up to 99 individual zones for paging using
standard DTMF tones through a POTS telephone line. When the MPI is connected
to the i.Net’s web appliance, programming can be set for up to 1.5 million square
feet of space through a single device.
The Local MPI-2 Rack Unit completes the i.Net system for local communication.
i.Net is THE most sophisticated sound masking system in the industry.

music for testing/troubleshooting the paging lines.
•Single turn pot to adjust the paging and music input signals levels.
•Ability to connect a Global MPI.
Inputs
•Power input.
•Analog phone line input (RJ11).
•Ground 2-pos terminal block (screw terminals).
•Microphone inputs (individual wires and RCA).
•Music inputs (RCA).
•Global MPI (RJ45).
•Data from the head-end (RJ45).
•Break tones 4-pos terminal block (screw terminals).
•Doorbell 4-pos terminal block (screw terminals).
•Message Triggers 6-pos terminal block (screw terminals).
Output
•Data output to OPs (RJ45) with two audio sources.
LEDs
•Power –solid when the unit is powered.
•Status –blinks during boot-up and audio test, solid when paging or IR
remote button is pressed.
•Page On –solid during an active page.
•Audio input level –two sets of three LEDs for paging and music input level
detection. Yellow = low or no input. Blue = good audio level. Red = audio
input too high.
•Activity - Rx –blinks when Neuron is receiving data Tx –blinks when
Neuron is transmitting data.

Front Panel
1. Power LED
The power LED indicates power to the
unit.
2. Activity LEDs
The activity LEDs indicate LON activity.
3. Source Selected LEDs
The source selected LEDs indicate
which source has been selected to play
on the internal speaker.
4. Source Select pushbutton
Used to select the audio source to play
on the internal speaker (source 5 for
music, source 6 for paging).
5. Audio Test pushbutton
Used to start and stop the audio test on
the paging lines.
6. Page On/Off
Used to start and stop a page for audio
connected to the MIC input.
7. Status/Page On LEDs
The Status LED will flash while the unit
is booting up and on when a page is
active. The Page LED will be on during
a page.
8. Audio Level LEDs
The audio level LEDs indicate the audio
input level for paging and music.
9. Input Page Volume
The input page volume adjustment is
used to increase the page volume.
10. Input Music Volume
The input music volume adjustment is
used to increase the music volume.

Rear View
11. To Global MPI
Connect an RJ45 cable to the optional
Global MPI.
12. MIC
The 5-position MIC input is for a
microphone input.
13. MIC
The RCA MIC input is for a line-level
microphone input.
14. Music
The RCA music input is for line-level
music.
15. Phone
The RJ11 phone input is for a POTS
appearance phone line.
16. Data
The RJ45 data connector “HE” connects
to the Head-End “To OP” connector
while the “OP” connects to the OP
“Data In”connector.

Wiring
To Global MPI
The addition of a Global MPI-2 is optional. The Global MPI-2 allows the user to
page all buildings with a Global MPI-2 simultaneously. The “To Global”MPI
connector is for communicating to the Global MPI. Wire the “TO GLOBAL MPI” to
the Global MPI’s “TO LOCAL MPI” connector using an RJ45 cable.
Microphone Input
The microphone input is for a dynamic microphone.
Connect a microphone to the “MIC” connector using individual wires from the
microphone.
SIG+/SIG- = MIC audio
SHLD –MIC shield
SW/SW = MIC key switch
5

Microphone RCA Input
The Microphone RCA input allows a line-level microphone input to be used for
paging.
Connect a line-level microphone signal to the MIC RCA connector using an RCA
cable.
Music Input
The Music input is for background music.
Connect a line-level music source to the MUSIC input using an RCA cable. The
left (L) and right (R) inputs are summed together internally.
Phone input
The Phone input is for phone paging.
Connect a POTS appearance phone line to the PHONE connector using an RJ11
cable.
6

Data
The Data connector is used for communicating to the head-end and to the OP.
Connect the “HE” to the head-end “TO OP” connector using an RJ45 cable.
Connect the “OP” to the OP Data In connector using an RJ45 cable.
Break Tones Input
The Break Tones input connector is used to trigger one of two break tones.
Connect a normally open dry contact to “1” and “C1” for break tone #1 and/or “2”
and “C2” for break tone #2 using 16 AWG wire.
