Solari’s highly flexible MCK 2245 and MCK 2245eth are microprocessor-based master clock devices designed to act as master in a centralised clock system, control acoustic alarms  and lighting systems. These clocks be made to synchronise a number of slave clocks as well as to signal programmed events by implementing optional devices. The microprocessor-based CPU handles all data relative to the embedded perpetual Gregorian calendar with automatic daylight-savings time adjustment.
Optionally, the MSK clocks can be externally synchronised via DCF77 or GPS. A standard rack mounting version known as MCK 2245rack is also available for rack mounting applications.
