SISS maintenance across the GWR network
Planned and corrective maintenance of CCTV, CIS, PA and Help Points at managed stations and depots, with a customer helpdesk, CCTV downloads and the asset database.
Public Address
Station public address surveyed, designed and maintained within station information and security system (SISS) scopes.
Overview
TDM surveys and designs PA locations as part of customer information system projects, and maintains PA assets within station information and security system maintenance where a contract names them.

Survey
On customer information system projects, TDM surveys both the CIS and the PA installation locations. Those surveys record existing equipment, migration requirements, data connectivity, electrical capacity and containment, and they feed the detailed design.
On station schemes, a PA survey and acoustic modelling come before the installation.
