Arundel Castle

Arundel Castle

Background

Situated in magnificent grounds overlooking the River Arun in West Sussex, this picturesque castle was built at the end of the 11th century and is now the family home of the Duke & Duchess of Norfolk.

The Needs

Since the castle is open to the general public, it is essential for there to be an effective emergency lighting system so that visitors can exit the building safely in the event of a mains failure. However, this requirement had to be accomplished without affecting the overall ambience of the building.

The Solution

With aesthetics such an important consideration, the castle’s building services consultant, Wilson & Partners, made the decision to use static inverters to power the emergency lighting system. “Rather than installing lots of self-contained emergency luminaires, which would have been out of keeping, we opted for the static inverters as they enabled a wide variety of existing tungsten light fittings to function as emergency lighting during a mains power failure,” said a spokesman.

Menvier static inverter units from Cooper Lighting and Safety were duly selected. Providing instantaneous switchover on mains failure, the static inverters convert DC power from built-in standby batteries to 230V AC 50Hz single-phase power.

Initially, two static inverters - a 2kVA unit with vented nickel cadmium batteries and a 4kVA unit with sealed lead acid batteries – were installed in the main switch room at Arundel Castle to power the chandeliers and wall lights in the Baron’s Hall and the Picture Gallery.

These static inverters performed so well that the same approach was adopted for the Drawing Room, with two compact 500VA units subsequently being installed to provide emergency lighting. Subsequently, the 500VA compact static inverter was also specified for the Library, which is one of the most impressive rooms in the castle.

All installation work was carried out by the Hove branch of EDF Energy Contracting.

The Result

The consultants were delighted with the performance and reliability of the static inverter units – and with the level of support they received from Cooper Lighting and Safety.
