1. INTRODUCTION
1
Interalia's Digital Voice Announcer is a
microprocessor based audio recording and
announcement system. A recorded message plays to
a telephone line when the announcer is called. The
audio recordings are stored in a solid state medium
(ie. no moving parts).
The SMU, DMU, MMU2-4 and MMU2-6 are one,
two, four and six line announcers respectively. They
can be ordered with the following options:
•recording time from 32 seconds to 17 minutes
•remote access
•AC or DC power supply
•battery backup
•low impedance audio output
To determine the options installed in a particular unit,
locate the model number code on the rear of the unit
and compare it to the model number description chart
in Appendix C.
The amount of memory installed in an announcer
determines the recording time. The total recording
time is displayed on power up.
The announcer will not answer a caller until a
message has been recorded and turned on. Messages
may be recorded using:
- a telephone handset
- a microphone
- a tape unit
- a remote access telephone line (optional)
Messages can be recorded from a remote location
over a standard telephone line on an announcer
equipped with the remote access option. Remote
operations are performed using a touch-tone
telephone.
Announcer's equipped with battery backup operate
for up to two hours, from a fully charged battery, if a
power failure occurs.

2. INSTALLATION
2
Take the following precautions when working with telephone lines:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the
network interface.
•Use caution when installing or modifying telephone lines.

Applying Power to the Announcer
On systems with an AC Power Supply, connect the
detachable power cord between a 110/120 (or
220/240) VAC outlet and the announcer. On systems
with a DC Power Supply, connect 48 VDC between
the '+' and '-' screw terminals and connect GROUND
to the GROUND screw terminal.
Turn the battery switch ON if the announcer is
equipped with battery backup.
Verify that the Eight Character Display illuminates
and indicates the system configuration as shown
below. If the front panel display does not illuminate,
ensure that the power is being supplied to the
announcer. If power is supplied, remove the unit's
cover and check the condition of fuse F9. If the fuse
is intact and the display still does not illuminate
contact the nearest Interalia office for technical
assistance.
The display shows the software version, ie:
V5.00
followed by the 'system' remote access code:
8615
if configured for a combined announcement/remote
line:
COMB REM
followed by the line operating mode, ie:
RRRRRR
This example shows lines 1 to 6 operating in the ring
start mode. The line operating mode is indicated as
follows:
C - Continuous Play (C)
L - Level Start (L1, L2 or L3)
M - Pulse Start / Pulse Return (P2)
P - Pulse Start / Level Return (P1)
R - Ring Start (R, R*, RN, RT)
S - Synchronized Continuous Play (S)
-- - Line not available

This example shows that message 1 is assigned to
line 1, message 2 to line 2 ... and message 6 to line 6.
'--' indicates the line is not installed
followed by the total recording time available, ie:
2:11
and finally the line status:
I I I I I I
Connecting Telephone Lines
NOTE: On SMU models only line 1 is available, on
DMU models only lines 1 and 2 are available and on
MMU2-4 models only lines 1 to 4 are available.
RJ11C Modular Jacks
Use the RJ11C modular jacks to connect lines
operating in the Ring start mode.
Connect the telephone lines to the announcer through
FCC/DOC approved RJ11C modular plugs. Insert
the modular plugs into the modular jacks on the rear
of the announcer. Connect line 1 to J1, line 2 to J2,
... and line 6 to J6.
NOTE: If desired, the 50 position connector can
alternatively be used to connect lines operating in the
Ring start mode.
50 Position Connector
Use the 50 position connector to connect the
announcer to telephone lines or PABX trunks.
On the 50 position connector, each line (except
Remote) has:
•a Tip/Ring pair,
•Start '+/-' inputs, and
•Common (C), Normally Closed (NC) and
Normally Open (NO) Control Pulse (CP) contact
outputs.
The Tip/Ring pair acts like a regular telephone
extension on lines operating in the Ring start mode.
On lines operating in other modes, the Tip/Ring pairs
provides the message's audio output.
The Start '+/-' inputs initiate message play on lines
operating in the Pulse or Level start mode. The
message starts playing when a voltage, greater than
20 VDC, is detected between the Start '+/-' inputs.
The CP outputs indicate the message play status in all
operating modes.
Use Figure 3A for lines operating in the following
modes:
•Ring Start (R, R*, RN, RT)
•Pulse Start / Level Return (P1)
•Level Start / Level Return - Single Play (L3)
Use Figure 3B for lines operating in the following
modes:
•Continuous Play (C)
•Synchronized Continuous Play (S)
•Pulse Start / Pulse Return (P2)
•Level Start / Pulse Return - Single Play (L1)
•Level Start / Pulse Return - Multiple Play (L2)
NOTE: Appendix A contains a set of tables
describing how to connect the 50 position connector
to telephone lines and to some common PABXs.
Announcement / Remote Line
If configured for Separate Announcement / Remote
Lines, Line 6 is a dedicated announcement channel
operating in the mode specified by the option
switches. The Remote line, operating in the Ring
start mode, is a dedicated remote access channel.
Combined Announcement / Remote Line
If configured for a Combined
Announcement / Remote Line, Line 6 is not available
and the remote line, operating in the Ring start mode,
provides both announcement and remote access
features.
NOTE: The Remote line operates only in the Ring
start mode.
