Grassalkovich Castle, Hungary

The historic Grassalkovich Castle in Gödöllő was built in the mid 18th century, the largest in Europe and is second only to Versailles. During the Second World War, the castle fell into a state of disrepair, until large-scale renovation works began in the late 20th century, with a focus on making the venue suitable for hosting major events.


As part of the renovation works, the castle’s building services were needed to be upgraded to meet modern standards. Elektrovill won the contract to design, supply, install, commission and maintain the fire detection system. They recommended a system that is based around Apollo’s XP95 analogue addressable technology.

The Solution

Around 70 XP95 smoke and heat detectors were arranged in three zones and are controlled by Global Fire Equipment’s Juno-Net panel. As a result of Apollo’s open protocol and extensive XP95 range, there was greater freedom of choice when designing the system. Apollo interfacing devices, such as input/output units and switch monitor units, were used to enable the Apollo fire detection system to link with other critical equipment including aspirating detectors.

The Verdict

Ákos Kürti, Managing Director of Elektrovill Ltd, said:

"Apollo technology was chosen to protect this venue because of its reliability. When you are protecting a venue as historically important as this, it is important that your fire detection is completely trustworthy. "
