1.4 SYSTEM DESCRIPTION

A. INTRODUCTION.

A centralized Public Address System with all major equipment including amplifiers, central controller, music sources, etc to be located at a central control room shall be provided for this international airport terminal. The loud speakers distributed in each zone shall be connected to the central equipment using fire rated cables. Free standing 19” racks shall be provided for housing the central equipment. This is a multi-function system comprising several sub systems that, when integrated together, form a complete system for airport announcement and message management.

This system shall take care of the amplification, routing and switching of the various audio signals to the various pre-defined zones. The audio signals shall also include transmission of background music, operator announcements, fire evacuation calls, boarding calls, automatic announcement system calls etc.

All the lines (loudspeaker lines, modulation lines, remote control lines) shall originate from the PAS central Technical room.


<Project Title>


There are two types of zones. One for the public address system areas, which are divided into number of PAS zones in accordance with the needs of the public areas and one for the fire alarm system. The zoning of PAS is a subdivision of the zoning of FAS in accordance with NFPA codes.

The PAS zoning is as indicated in the PAS schematic diagrams. The type and quantity of PAS loud speakers, and their locations shown on the PAS schematic diagrams and PAS layout drawings are indicative and for guidance only. The contractor shall be responsible to provide a full functional system based on and by conducting a detailed acoustic study of the various areas fully complying with DCA requirements. The system design shall be based on the following criteria:

1) Average sound pressure level: 80 to 85 dB with respective amplifiers set at 60% of maximum volume,

2) Intelligibility index: STI: better than 0.50 in public areas at 30% occupancy

3) Sound diffusion level: 15 to 20 dB (A) above ambient noise level4) Total harmonic distortion:5) Electronic: less than 1% at specified output level

a) Acoustic: less than 3% at specified output level6) Frequency response: +/- 3 dB over 100 Hz to 18 kHz7) Uniformity of coverage: +/- 3 dB (0.25, 0.5, 1, 2 and 4 kHz)

VIP lounges shall be provided with an independent amplifier complete with a background music sources (Multi-CD changer) along with a local paging microphone. The central system will have an over-ride control over the local system, in the event of emergency etc.The loud speakers of the various zones shall be connected to the central equipment using fire rated cables.

B. Purpose

The public address system is mainly used to:
