Megavoice 2000 PABX-PA -interface
A Public Address (Speaker
announcement) interface
for telephone PABX. The annoucements can be placed from any telephone or from
remote location.
The announcement can be done by calling an extention number of the PABX (
like 66 or *1 etc. ) and
Megavoice answers this call. Caller gets beep tone and can start an announcement
through out thespeakers. Caller hangs up and the Megavoice frees the connection. Announcements
can be placed
through PABX from GSM or external telephone if allowed by PABX.
Megavoice detects the busy tone send by the PABX after call is cut to release
the announcement.
The connection is also timer limited to maximum 3.5 minutes. Busy tone detection
is adjustable.
Megavoice 2000 PABX-PA has 2 separate input lines and unbalanced outputs
for the PA-system.
Standard Megavoice 2000 PABX-PA has 2 lines. Each line can drive individual PA
amplifier and
speaker zone. One line can be connected to all amplifiers input to create
announcement to all zonesif amplifiers have at least two inputs. Audio outputs
have 1000 V isolation transformers and opto-couplers for 20mA control loop wires. Each line has a opto coupler inputs
5...12Vdc for starting
prerecorded announcements like fire alarms or evacuation instructions.
Megavoice 2000 PA-PABX -interface
A Public Address (Speaker announcement) interface
for telephone PABX. When the PA-system makes an announcement, Megavoice makes an
announcement though the PABX system and gives the same announcement via speakers
of the free
feature telephones. Also alarms, like fire-alarms, can be placed this way
through the telephones.
Megavoice 2000 PA-PABX gets relay information or control voltage from the
PA-system
( "tangent signal"). The Megavoice takes a PABX analog extention, dials special
announcement prefix
( like 66 or *1 ) and connects the PA-signal to PABX-extention till the
announcement is ended.
The announcement is heard through the free feature telephones. PA-PABX has 2
lines and therefore can
divide the announcements to 2 different telephone groups.
Some features are related to the PA- and PABX-system. Examples above are
normal installation cases.

Megavoice 2000 ATIS : Air
Traffic Information System
A client can call with a cellular or ordinary
telephone to Megavoice, which
answers the call. It then gives ATIS announcement from external source and hungs up after a
predefined delay. Megavoice
has two simuntaneus telehone lines to be connected to the analog telehone trunk
or PBX extention.
Eg. the announcement can be 30 s and the answering time 60s, which is remote
programmable time.
The ATIS line is eg. -10dBm 600 ohms analog line and the Megavoice adjusts it to
the telephone network.
Megavoice 1000 CD
-interface
A CD-player or radio can be connect to this adapter and it connects the audio to
the PBX's analog
extention, where it can be used as a continuous voice for PBX music on
hold or other funtions.
Megavoice 1000 PBX-PA interface
This is a inexpensive interface which makes it possible to make
PA announcements through out the PA speakers and amplifier using standard
telephone. This connects
to the analog trunk of the PBX and the PA-amplifier audio input and gives a
normal open relay contact
to switch the amplifier on line.
