Frequently Asked Questions

Can the digital clock be used as an independent clock?
No, the V-D2425 and V-D2440 digital clock requires a communication input and must be used with either a master clock or a V-D11025A or
V-D11040A digital clock.
Some clocks require a 9 volt battery backup for timekeeping. What happens to the V-D2524 or V-D2540 if a power failure occurs?
Upon restoration of power, the clock immediately receives a correction signal from the master clock and resets itself to display the correct time.
This occurs within seconds of "power-up", so no battery backup is required for a timekeeping base within the individual clocks. Since the clock
does not require a battery backup, the clock never needs to be opened.
How can I interface the V-D2524 or V-D2540 with Rauland, Dukane and other systems?
The V-WMCA Master Clock or the V-D11025A or V-D11040A digital clock can be used as an interface between other systems and V-D2524 or
V-D2540 clocks.
What happens if voltage on the power line drops from 24 VAC to lower voltage?
The clock will still function, and will maintain the same level of brightness. However, the current consumption will increase proportionally to the
decrease in voltage.
