Some alarm equipment on the wall of Cavendish House, possibly still capable of ringing. Kindly, John Webb has some illuminating details about them: These are sprinkler alarm gongs. If the sprinkler systems are active, then these will ring. They are powered by small water wheels turned by a small flow of water diverted from the operating system. The systems almost certainly are monitored by more modern communication methods to raise an off-site warning of operation or faults.
