Simplex’s Wireless System begins with a master clock that includes a transmitter which sends the accurate time to the secondary clocks.

The Simplex Wireless System allows customer to install clocks themselves. A unique feature of the system is that each wireless clock not only receives the accurate time and corrects itself, if needed; it will also retransmit the time to the surrounding clocks in its area.
This way one clock can receive the time signal from multiple directions. The wireless clocks receive and transmit the signal from other clocks on the same floor and / or other floors.
