A number of wired clock and bell systems are located in hospitals, schools and businesses. In the last decade there was a shift in the market towards wireless clock systems. The main reason for this is the flexibility of the placement of the time display.
Wireless lets you place a battery operated clocks anywhere that you need them. The advantage of using an existing wired system is that you already have power where your clocks are currently located.
Granted your current clocks may not be accurate but that is a separate issue and probably has nothing to do with the power.
We recommend that you consult with us on the best system given your current situation. Many cases that involves implementing a hybrid system where you would use wireless and wired. It can save your organization a lot of money and installation time.
