The existing PA systems ... . The PA systems will be upgraded by the replacement of the core control equipment. The design of the upgraded PA systems will in general comply with the latest codes of practice for Fire Service Installations issued by Fire Services Department of HKSAR and international standard BS EN 5839 Part 8.

The scope of the Works includes ... :

Replacement of the backend equipment of the existing PA systems in 9 nos. of MOL stations and 5 nos. of TKL stations with a fully IP-based PA system supporting flexible group stations control configuration. The field equipment (e.g. speakers, speaker cables and noise microphones) of the existing PA systems will be re-used by the IP-based PA system;
 
Provision of a PA Cloud Platform with high availability to accommodate all control and monitoring functions and common Human Machine Interface (HMI) in all stations. This cloud platform will be equipped with expansion capability to cover all railway lines or will be able to be migrated to other platforms in the future;
 
Provision of a common web-based PA HMI to enable station and OCC operators to control and monitor the IP-based PA system. The HMI will be equipped with open protocol interfaces to integrate with different PA systems in other railway lines in the future; and
 
Provision of condition-based monitoring functions with automated Sound Pressure Level measurement of PA system performance by the IP-based PA system.

算唔算得上全線換/upgrade PA system 嘅前奏?
