Synchronized Clock Systems

A synchronized clock system provides the exact same time to all clocks in the system. The synchronized clock system typically consists of a “master clock” and multiple “secondary clocks.” The master clock communicates with all the secondary clocks providing the entire system the exact same time, so no matter where you are in the building the time shown by all clocks will be uniform and accurate.

In a synchronized clock system, the master clock receives time from either an NTP server or GPS receiver, or its internal clock can be utilized as a time source. When the master clock has received the correct time from either source, the time is then distributed to all secondary clocks in the system. The signal is sent to the clocks multiple times per day, ensuring that all clocks stay synchronized and do not drift from their accurate time.

There are many benefits to using a synchronized clock system. The main benefit is that everyone in the building or buildings is following the same time source eliminating confusion. Other features that synchronized clocks provide is the elimination of correcting the time on all the clocks when Daylight Saving Time occurs or in the event of a power failure, the system will automatically adjust to the correct time as soon as the power returns.

The master clock (depending on the model) may also include scheduling capabilities, which enables the user to program the ringing of bells, turning on heating and air conditioning at predetermined times, and control many other devices as needed. Another popular feature is the Count Up and Count Down function, which allows the user to show elapsed time between breaks, between shifts, for “Code Blue” situations in operating rooms, and for many other applications.

Important Considerations
• Do you need your clock system to perform notifications such as ringing bells or
    sounding alarms?
• How reliable does your clock system need to be?
• Would you benefit from a clock system that can automatically adjust for Daylight
    Saving Time?
• If you are performing a retrofit, do you need your new clock system to interface
    with your old one?
• If you decide to install a wired system, will you use existing wiring in your facility?
• Could you save the most from a clock system that is energy efficient?
• Is there a system that costs little to implement?
• What type of accuracy does your master clock need?
• What degree of accuracy do your secondary clocks need?

• Reduces confusion
• Staff attend meetings on time
• Deadlines are met
• People and processes run on time, synchronized
• Improved adherence to breaks and lunchtime
• Improved efficiency
