HEATHROW AIRPORT is to conduct a major upgrade of the emergency lighting at Terminal 5, less than 10 years after its opening.
It is decommissioning its existing central battery units and replacing them with 23 new units in a £2.2 million project.
The new installation works and commissioning will be carried out during non-operational hours over a 23-week programme to avoid disruption. It covers all three buildings at Terminal 5.
The full integration of the self-contained and central battery units at Terminal 5 was a major innovation at the time. Testing and monitoring is performed by the general Dali lighting controls, making it the world’s largest single Dali emergency lighting system.
Using Dali avoids duplication of systems and resolves any compatibility issues. The Tridonic Dali emergency lighting control units automatically test, monitor and provide the monthly reporting. Automation of emergency lighting testing in this way eliminates much of the costly visual inspection required with conventional systems
The lighting system is monitored and controlled with the aid of the KNX management system from Andromeda Telematics. Over 2,900 intelligent switch interfaces and 870 control panels containing KNX/Dali gateways were installed in the terminal, all linked via the KNX control system. All the data from the Dali system is fed back through an IP-platform to a building integration system
The contract to refit the central battery units has been won by SPIE UK – original contractors at Terminal 5 – and will be completed at the end of October 2018. Terminal 5 opened in 2008.
Heathrow Airport Terminal 5 opened its doors in March 2008.
At the time of its opening, Emergency Power Systems, a Sheffield based company now acquired by Vertiv, installed the existing Emergency Lighting Static Inverters. Ten years on, this equipment requires replacement due to the new LED lighting instalments included as part of the major refurbishment programme.
Static Inverter systems typically have a longer lifespan than many UPS derivatives. In their day, they were a technically advanced system designed to meet Heathrow Airport Specification.
In December 2017, Vertiv won the project to replace 23 static inverters for Heathrow Terminal 5. The replacement project begun early in 2018 and is continuing until the end of the year when all systems are replaced; whilst keeping the Terminal operational.
The new systems are Vertiv’s ELSX Static Inverter which has a fully modular hot-swappable design that ensures that servicing or any repair time of the life safety system is kept to a minimum, which fully satisfied Heathrow’s specification. The systems are compatible with LED lighting and all types of fluorescent and HID lighting.
The 23 systems will be used to provide life safety lighting protection to the airport’s concourse areas and terminals. They will all also be designed, manufactured and tested at Vertiv’s Sheffield Facility. Vertiv was the supplier of choice due to the long-standing history and relationship with Heathrow Airport. To date, Vertiv has over 5MW of systems in Heathrow, both UPS and Static Inverters.
