Leeds University Music School

Background

The University of Leeds School of Music, which is centred around the Clothworkers Centenary Concert Hall, was being extended and refurbished. As part of this process the emergency lighting in the department was upgraded.

The Needs

The primary need was for an emergency lighting system that complied with current standards to ensure that occupants could leave the building safely in the event of a power failure. In addition, the University was very keen to reduce maintenance requirements wherever possible in order to minimise ongoing costs.

The Solution

Rather than opting for self-contained emergency luminaires throughout the building, the University decided to use several Cooper Lighting and Safety central battery units with slave luminaires.

According to Alan Hansell, the University’s technical officer responsible for fire alarms and emergency lighting, the main factor in the decision was the need to minimise maintenance costs. “If you have hundreds of self-contained emergency luminaires installed around the building, each one has to be checked regularly, and batteries frequently need to be changed because they have a life of only 3-5 years,” he said.

“With a central battery system, battery life tends to be longer – sometimes 10 years or more – and when they do eventually need replacing, it’s a quick job carried out at just one location.” A total of six CeaGuard CG48 central battery units were installed in the School of Music, all networked to an application controller, which provides central control and monitoring facilities. Should a mains failure occur, the CeaGuard units deliver emergency power to over 200 Eurolite, Vistral, Weatherlite and Safe Edge slave luminaires.

The Result

As well as helping the University to reduce its maintenance costs, the CeaGuard CG48 system also handles the regular checking of emergency luminaires, automatically performing the requisite weekly functional tests and annual full-duration tests using mainsborne signalling, which eliminates the need for any additional cabling.

“We’ve used the CeaGuard units in other buildings at the University,” commented Hansell, “and they have proved to be the best option for us – both in terms of life-cycle costs and ease of compliance with legislation.”
