Valcom Wireless Analog Clocks Digital wall clock Circle Black,White

16” Round Wireless Clock Black, Surface Mount, Battery Operated 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 analog wireless clocks are available in battery (2 "D" cell), 24 VDC/VAC and 110 VAC. Each Valcom clock receives the wireless signal and then becomes a repeater. This means each clock in an area increases the quality of the signal as it perpetuates through the building. The battery powered clocks transmit and receive the signal once every four hours (in order to conserve battery life), at 12, 4 and 8 o’clock. 24 volt and 110 volt models transmit and receive data every minute.
