A master clock is a central timekeeping device used to synchronize the time across multiple slave clocks or systems within a facility. It ensures all connected devices—whether analog, digital, or network-based—display the same, accurate time.
Key Features
Time Synchronization: Syncs all clocks across a school, hospital, airport, or office.
NTP/GPS Inputs: Receives time signals via Network Time Protocol (NTP) or GPS for high accuracy.
Multiple Outputs: Supports wired (RS485, relays) or IP-based (SNTP, PoE) connections.
Event Scheduling: Some models allow bell or alert scheduling for schools or factories.
Web Interface: Manage settings remotely through a browser interface.
Master clocks are used mainly in Schools to manage class change bells, hospitals for medical procedures, government & financial institutions for accurate time stamping, transport hubs to rely on consistent time tables.
