A conventional
pendulum type large clock moves the hands in a progressive manner, and
takes many steps to complete the movement form one minute to the next.
Most master clock systems move the minute
hands in 1-minute steps, and does not have a particularly natural feel to
its movement. This master clock system uses proven industry standard
hybrid stepper motors to increment the movement of the minute hand at the
rate of 60 steps per minute, thus the clock face provides a smooth
progressive look to it's movement.

Designed
and built to meet many requests for this feature, the master clock system
also provides the following features:
- Atomic clock radio broadcast linking for
total accuracy and immediate winter/summertime time changes
- Designed as a replacement for Turret Clock
applications where the original clock has been removed, or as a new
installation
- In the event of power failure, the unit
will intelligently reset to the correct time when power is restored.
- Standard unit includes Westminster or
Ting-tang quarter and hour strike outputs with night silencing
options.
- Available with integrated motion work for
centre-fixing applications, or as central drive unit to drive many
individual motion work assemblies as in a traditional multiple dial
installation.
- Multiple drive units can be driven from a
single control unit. There is no reasonable limit to the number of
dials of any size that can be controlled from one control unit.
- Can drive dial sizes up to 8 ft (larger
sizes available to order)
- Battery back-up options for accurate time
display in the event of power failure
- MSF disciplined crystal oscillator back-up
to provide accurate time display during MSF non-availability.
- Sealed lubrication for drive unit and
motion work to provide very low maintenance operation
- Ruggedly built, tamper-proof and sealed to
military standards and driven from standard mains power supply with
low voltage outputs for safe connectivity and operation.
- Drive unit size: 160 x 160 x 120mm.
Control Unit: 200 x 200 x 120 mm.
- GPS controlled version with user
programmable daylight saving options available June 2003
