In March 2001, TVF were awarded the contract to supply a new fire alarm system at St George's Chapel, Windsor Castle. A major component of the alarm system is the Aspiration Detector System which was supplied by Kidde Fire Protection. Overall, the new fire detection system will provide quicker reactions, will be easily maintainable, and will function in a discrete capacity in tune to its surroundings.

The system is based on six Hart XL High Sensitivity Smoke Detectors connected to an existing Procyon control panel from Kidde. The Hart XL HSSD uses an internal laser to count and discriminate airborne particles, providing early and reliable warning of the first signs of combustion. It is particularly suited to this delicate environment as it can be installed with the bare minimum of downtime and has non-intrusive aesthetic design qualities. Point Detectors are used to detect fire or overheated situations in less sensitive areas and are to be coloured and installed so as to be less visually obtrusive than the existing detection system. Monitoring is executed by the Windsor Castle Fire Brigade.

The installation programme was designed throughout for an efficient and reliable changeover. This is facilitated by the capacity of the Hart XL HSSD units to be integrated into the existing Windsor Castle Fire Detection System. The integrity of the existing system is maintained by TVF, resulting in a greatly enhanced and extended level of protection throughout the main body of the Chapel.
