What is pull bell?

A pull bell, also known as a rope bell or a manual bell, is a device used to signal for attention, usually in large buildings or institutions. It consists of a rope or cord attached to a clapper inside a bell or gong. When the rope is pulled downwards, the clapper hits the bell, producing a ringing sound. Pull bells were commonly used in schools, churches, and factories before the advent of electrical and electronic signaling devices. They are still used today in some historical buildings and as decorative pieces. The sound of a pull bell is typically loud and clear, making it an effective means of communication in noisy environments.
