General Specification
Intercom and Public Address System
1. INTERCOM AND PUBLIC ADDRESS SYSTEM
1.1 GENERAL
The system shall consist of a full duplex intercommunication system to provide digital voice
communication, public address, voice recording and event logging facilities.
The following functional features shall be provided by the proposed system:
a.
Noise immunity
The system shall provide clear undistorted speech and music transmission.
The audio signal shall be digitally transmitted to each intercom station to provide immunity
against electrical and earthing interference typically associated with analogue systems.
b.
Bus structured Cabling
Intercom station cabling shall be installed in a BUS configuration to reduce system cabling
and conduit requirements, and shall not require an independent pair of wires per station.
c.
Multiple Audio Channels
The system shall be capable of transmitting a minimum of three digitized audio channels
simultaneously, which shall enable intercom stations to independently select either a music
channel, an education channel or to call and communicate with the system operator. The
channel selection and current operation of one station shall have no effect on the channel
selection and operation of any other station.
d.
Interface to Telephone network
The system shall have the capability of interfacing to the prison telephone system (PABX),
which will enable existing telephones situated in offices to call intercom stations and hold
two-way conversations. The telephones shall also be used for paging over the public
address system.
e.
Tamper detection
Each intercom station shall provide tamper detection, which shall automatically notify the
system operator of an intercom station, which has been opened or tampered with in any
way.
f.
PC based Operator console
A dedicated PC based operator console shall be provided at each local control room and at
the Central control station. It shall be possible for any operator console to call any intercom
station within the entire prison based upon authorized user levels. In the case of failure of
any operator console it shall be possible to route incoming calls from intercom stations to
any other operator console in the prison.
g.
Event Recording and Reporting
The system shall be capable of recording and reporting the following events with an
accompanying time and date stamp:
Intercom station call requests with station identification.
Operator response with operator/station identification and call duration.
Intercom and Public Address System specification (Rev_July 2003)
Page 4
General Specification
Intercom and Public Address System
h.
Threshold Monitoring
The system shall be able to automatically detect raised voice levels in cells and
passageways. It shall be possible to independently set the threshold (Trigger) level of each
intercom station to suit the environment. Threshold alarms shall be transmitted to the system
operator and treated as emergency calls.
i.
Voice recording
Emergency calls shall be recorded onto a PC hard drive. System operators shall be able to
replay the emergency call via a PC based control system, which shall indicate the
associated intercom station and time and date of the call.
j.
Two way conversations
The system operators shall be provided with handsets, which shall enable two-way
(telephone type) conversations with any selected intercom station.
k.
Volume level Adjustment
The system shall enable operators to independently set the speaker volume and microphone
sensitivity levels for each intercom station in order to optimize the acoustic settings for each
building or room.
l.
VoIP Compatibility (Ethernet telephones)
The system shall be compatible with standard Voice over IP telephone systems, which will
enable the expansion or replacement of equipment with products from a variety of
competitors. The system shall be able to transmit multiple audio conversations between
buildings via existing Ethernet networks.
System Description
Intercom stations shall be connected in a modular bus configuration in order to reduce
cabling requirements. Point to point systems shall not be considered acceptable.
Analogue/digital hybrid systems making use of separate data and audio bus cabling shall not
be accepted, and the tenderer shall provide sufficient technical literature to fully evaluate the
data/audio protocol utilized by the system.
The system shall be compatible with standard voice over IP products (IP Telephony), which
employ such protocols as SIP, and be capable of communicating both data and audio
signals over standard TCP/IP and UDP Protocols. Where possible the system should make
use of existing Large Area Networks for the transmission of control and Audio data.
The overall design of the system software and cabling shall be such that as far as practical,
failure of one part (building) of the system does not affect normal operation of any other part
of the system.
The system shall employ full duplex digital audio technology and provide clear undistorted
speech communications, free from background noise and/or external interference.
Amplification shall be provided at each intercom or PA station in order to provide the option
of piping music to groups or individual stations as required.
The system shall be capable of transmitting at least 32 simultaneous full duplex
conversations via the TCP/IP network running between control areas, whilst being capable
of transmitting two simultaneous full duplex conversations across any local intercom station
Intercom and Public Address System specification (Rev_July 2003)

bus, in order to pipe music to all speakers, whilst simultaneously holding a conversation with
any selected intercom station.
The intercom system shall be capable of being fully integrated with a PC based Graphical
User Interface (GUI) via a bi-directional high level interface to allow remote monitoring of all
intercom station calls by the GUI. All such interfacing of systems shall be configured such
that if any one system fails to operate, the other systems shall continue to operate without
any detrimental effect.
A dedicated GUI for the control, monitoring and logging of events shall be provided for the
intercom system, and shall be installed at each control center.
1.1.1 Cell and Passage Door Intercom Stations
The contractor shall supply, install and commission a networked Cell and passage door
Intercom System to the locations nominated in the accompanying drawings. Monitoring
locations shall be provided in each local control room, with the primary central monitoring
location to be installed in the Central Control room.
