Long Line Public Address System

Supplier: Jacques Future Proof Communications

The Jacques Long Line Public Address (LLPA) System adapts the VoIP System - 650 Series to create a sophisticated Public Address (PA) system for use in transport and commercial applications


Jacques LLPA System is an extremely flexible design which encompasses the following major features:

• Live audio Public Address (PA) announcements at stations
• Allows PA announcements to be made from any location on the Local/Wide Area Network (LAN / WAN).
• PA amplifier output levels can be dynamically adjusted via the Jacques Ambient Noise Monitors (AMN)
• PA levels can be adjusted based on time of day while still adjusting for ambient noise
• Audible chimes (pre-announcement chimes) to indicate a PA announcement
• Pre-recorded messages can be directed to any defined location which can be dynamically selected
• Messages can be pre-recorded from each IPM-650PA for later playback
• Monitors speaker lines for faults and overload
• Can inject EWIS tones and handles press-to-talk (PTT) when interfaced with a Fire Detection System
• Provides digital or analogue background music which can be downloaded from a central server so the play list    can be changed as required
• Priorities can be set to allow certain calls to override calls of a lower priority
• Provides comprehensive event logging to show the operation of the system with selectable filters for faults and    normal call events
• High quality streaming audio with high intelligibility speech announcements
• System flexibility allows configuration based on the customers requirements

The system interfaces with:
? Passenger Information Networks (PIN). The Passenger Information Networks (PIN) provides information relating to train (or transport) movements at each Station, specific to the station.  E.g. PA announcements can be made specific to the scheduled train movements.
? Emergency telephone systems
? Security Management and Building Management Systems
? CCTV security systems
