Tunelový Rozhlas Case Study

Slovakian highway construction and maintenance company, Národná dialničná spoločnosť, a.s., recently deployed a sophisticated ASL Voice Alarm (VA) system for three motorway tunnels on the D1 and D3 motorways which bypass the city of Žilina
in Northwest Slovakia, spanning over 6km of road. The brief was to provide an EN
54-compliant system for a series of motorway tunnels to allow for the safe and trouble-free evacuation of people in case of a fire event or traffic accident. The system had to cater for acoustic challenges of tunnels and to be centrally controlled and monitored.

St Pancras International

The £1.2m contract included the required integration of over 8,000 field devices across 16 subsystems including CCTV, BMS, network switches, Passenger Help Points, ASL-supplied Long Line Public Address and Voice Alarm, Access Control, Passenger Information Systems (PIS), vehicle barriers and PABX.

Klang Valley MRT

The Klang Valley Mass Rapid Transit (MRT) railway line in Malaysia was the first of three new lines planned to serve the Greater Kuala Lumpur area, with 31 stations serving a population of 1.2 million. The 51km-long line required a multi-node distributed Passenger Information Display System (PIDS) to display live train information, synchronised PA/PIDS messages, images and logos, safety messages and billable advertising. This was also required to integrate with the Public Address Voice Alarm (PAVA) equipment, so that screens located on the station platforms would display emergency information and wayfinding in the event of an emergency.
