Wireless Master Clock Kit with Five 4" Digital Wall Clocks

Description

If you’re searching for a wireless master clock kit with five 4" digital wall clocks to keep every room on the same exact time, this “Clocks in a Box” bundle is built for fast deployment and easy expansion. Instead of dealing with wiring runs, drift, or manual resets, the included RF transmitter automatically broadcasts the correct time to your synchronized clocks—ideal for schools, shops, offices, warehouses, and medical facilities where accurate time matters.

The system uses a 1-Watt Wireless RF Mini-Transmitter with 128-channel 902–938MHz frequency-hopping technology for dependable signal performance in busy buildings. Time is sourced from NTP (Network Time Protocol) by default, with an optional GPS time source available when you want an independent reference. A battery backup helps maintain time continuity during power interruptions, minimizing disruption and avoiding building-wide time confusion.

For buyers planning growth, this kit is a practical base system: install the five clocks now, then expand later by adding more clocks to cover hallways, departments, or multiple work areas—without changing the time source or rebuilding your setup.
