How to set up a school bell?

Answer 1

If you mean and outside bell these were hardwired so in theory you cannot with them your self. If memory serves me it was called a Bell 80D - Loud external bell. BT also sold an indoor version, - the Bell 50E this could be plugged into the "standard" phone socket, as was provided free of charge to customers with hearing problems.

Hope this helps?
