Frequently Asked Questions
Can this digital clock be used as a standalone clock?
The Valcom Digital V-D110XXB can be used as a standalone clock, but it will not keep synchronized time
in this configuration. Instead, it will rely on an internal quartz oscillator for keeping the time. The clock will
drift by a few seconds each year while in this mode, and will need to be readjusted manually.
How can I use this digital clock with Rauland, Dukane and other systems?
V-D110XXB clocks can be added directly to several sync wire systems. Refer to the Inputs section of this
manual for instructions on how to connect the clock to each system type.
V-D24XXB-6 clocks can obtain time from these systems through a master clock working as a translator.
Data from the other system would be sent to the master clock, and then the master clock would send the
data to the digital clocks through 2-wire or wireless communication protocols.
What happens to the digital clock if a power failure occurs?
If a power failure occurs, the display will shut off but the clock will continue to keep time with its internal
quartz oscillator. This oscillator will continue to run on a tiny battery backup for about ten years. In this
mode, it may drift from synchronized time by a few seconds for each year that the clock is without power.
Once power is restored to the clock, the display will turn on and display the time on the quartz oscillator. It
will correct this to accurate, synchronized time once a signal from a master clock is received.
What happens to the digital clock if contact with the time data source is lost?
The digital clock will rely on an internal quartz oscillator for keeping the time until time data is received.
The clock will drift by a few seconds each year while in this mode, and will need to be readjusted manually.
The V-D110XXB digital clock is able to act as a master clock. If the communication input is lost to the
V-D110XXB, and the V-D110XXB is acting as a master, then the clock will send synchronization data to any
clocks down the line that are connected. This data will be based off of the V-D110XXB’s quartz oscillator,
so while the clocks will be synchronized to each other, they may not be showing accurate time.
How can I display “BELL” and “FirE” on the clock?
“FirE” and “BELL” are signals sent by the appropriate master clock. Refer to the master clock manual
for instructions.
For 24V clocks, what happens if voltage on the power line drops from 24V 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.
