To make a complete clock system operate, a number of pieces of ancillary equipment may be required.


A slug relay will lengthen the master clock pulses to make them suitable for a large tower clock dial.
Click on Slug Relay on the left for more details.


Where a master clock supplying half-minute pulses to its slaves also has a device requiring 1-minute pulses, the impulse converter creates the appropriate pulse.
Click on Impulse Converter on the left.


A Synchronator will produce pulses at one minute intervals suitable for a time recorder clock, without the need for a master clock.
Click on Synchronator on the left.


To allow signal bells to be rung at various times, a programmer can be inserted into the system.
Click on Programmer on the left for more information.
