Wireless Master Slave Clock System

The Wireless Master-Slave Clock System is an adaptable time-synchronization solution ideal for environments where flexible clock positioning is a priority. This system eliminates the need for extensive wiring, making it especially suitable for large, open spaces or sites with minimal infrastructure for cable installation. The wireless setup ensures synchronized time displays across multiple clocks with minimal installation effort.

Using a central master clock, the system wirelessly sends accurate time signals to all connected slave clocks, allowing seamless, synchronized timekeeping throughout an organization. This master clock receives a time signal via GPS or NTP to maintain high accuracy, which it transmits wirelessly to other clocks in the system.

The wireless design is particularly effective in buildings like hospitals, schools, and warehouses that benefit from easy clock relocation and reduced installation complexity. By relying on secure wireless communication, the Wireless Master-Slave Clock System offers both reliability and ease of scalability as operational needs grow or change.

When to Use Different Clock Systems
ParameterStandalone GPS ClockWireless Master-Slave Clock SystemWired Master Slave Clock System
Best UseIdeal for locations with open sky access, requiring only a single, standalone clock.Perfect for spaces with limited infrastructure, allowing flexible clock positioning and easy installation.Suited to buildings with physical barriers and multiple rooms, where wiring is feasible for stable time synchronization.
InstallationNo wiring or master clock dependency; each clock operates independently with GPS synchronization.Requires only a power source for each clock, with the master clock wirelessly connecting to all slaves.Requires RS485 or similar wiring for stable communication, ideal in structures with barriers like walls or floors.
AdvantagesExcellent for outdoor setups with accurate timekeeping, independent of a master clock.Flexible and scalable, with easy setup in large or dynamic spaces requiring synced time displays.Delivers consistent, synchronized time across multiple clocks, connected to a central master clock.
