Architectural Clocks > Products > Master Clock Systems

Four circuits (standard) to control any combination of clocks or auxiliary outputs.  Dry contact relay outputs. Add up to 12 circuits with EXP-4 expansion modules.  GPS time accuracy available with the MC100-GPS antenna.  Add LAN programming and NIST timebase with the WeM-MC100 adapter.

The MC100WP is the weather proof version of the MC100.  Four output circuits can control any combination of clocks or auxiliary outputs such as lights or bells.  Add GPS time accuracy with the MC100-GPS antenna.

The MC3 is the most cost effective solution for accurate control of National clocks or clocks by other manufacturers.  Three 120VAC solid state outputs can control multiple clock circuits simultaneously.  Battery-less backup provides time keeping for over 3 months during outages.  Automatic daylight savings and power outage adjustments.  Add GPS time accuracy with the MC3-GPS antenna.

These GPS antennas can keep your architectural clock accurate to the time kept by the National Institute of Standards and Technology (NIST).   The antenna communicates to the master clocks using serial data communications eliminating expensive antenna cable extensions.  Comes standard with a 30' cable, but can be extended if necessary.

If only manual control of the clocks is warranted, the 970 series control panel provides a toggle switch to advance or stop the clock mechanism. A light indicates when clocks are resetting. Single or multiple clock versions are available. A pilot clock can be used to aid setting when the clocks cannot be viewed from the panel location.
