Programme controllers

Controllers were used for operating electric bells, hooters, syrens and all other forms of warning signals, to a predetermined programme in exact synchronisation with the clocks in the premises.

This controller usually has a built in Duration Reducer limiting the sounding of bells etc. to approximately 10-12 seconds as 30 seconds was often found to be too long. An Automatic Week-end Silencer can also be provided and a mercury tube contact to carry 5 mps at 230-250 volts is a standard fitment.
