The emergency telephone system in the Sydney Harbour Tunnel is the culmination of 25 years of design experience.
Dosec designed, manufactured, installed and commissioned the emergency telephone system in place at the Sydney Harbour Tunnel. It is a critical system that meets strict requirements of high reliability and low maintenance.
After our initial system ran for many years without fault, Dosec was given the opportunity to update it according to Sydney Harbour Tunnel’s typical refurbishment procedures.
As the emergency telephones are a critical part of the tunnel infrastructure, the update was performed alongside the live system without interruption. New features were added that incorporated the most recent developments in electronics and communications, which brought the system up to date and functioning more efficiently while maintaining the reliability it had become known for.
These updates also provided easier to use interfaces in the control room, allowing operators to be more effective when assisting motorists during an emergency, and to perform the testing of the system more efficiently.
