The industry's most advanced analog clock. The RDS incorporates state-of-the-art microprocessing with infrared positioning sensing creating the most accurate timekeeping system. A powerful rotary stepper motor and indexing technology not only makes this the most durable mechanism, but it also has the lowest power consumption. Less than 10 cents per year! On-demand instant reset capability gets your clocks on time when you need it... now! An industry exclusive.

As the pinnacle of quality for synchronous system clocks, the EX Series has proven to be the longest lasting clock on the market. A powerful synchronous motor and wear tolerant mechanism design combine to create a truly "install it and forget it" system often times outlasting the building's lifespan. Available in both 24VAC and 120VAC to accommodate every installation. Single and double face versions up to 24" diameter.

There has never been an impulse clock like this! National Time, the modern-day founder of impulse clock systems, has been manufacturing impulse clocks since 1870!  The RDI clock combines this experience with today's technology to create an impulse clock system like no other.  A powerful Rotary drive stepper motor, infrared position sensors, and microprocessor technology are brought together to make the most accurate time system. Unlike any other impulse system, power and data are transmitted on the same wires allowing an industry exclusive On-Demand Instant Reset.  These intelligent clocks can also operate on existing 2-wire or 3-wire systems.
