Our innovative wireless system provides wireless clock correction to both analog and digital Valcom wireless clocks. The wireless system works on 915 - 928 MHz frequency hopping technology.The Valcom digital wireless clocks are available in 24 VDC/VAC and 110 VAC. Similarly to the analog wireless clocks each clock is a repeater. The digital clocks transmit the signal once a minute. They are available in both 2.5" and 4.0" models. The wireless system uses our versatile transceiver (part number V-WMCA) as a master clock. The V-WMCA transceiver features TCP/IP connectivity for time synchronizations as well as the ability to interface with other clock systems.A minimum of one V-WMCA Wireless Master Clock Transceiver or other time sources is required per wireless clock system.
