savings typically in excess of $10,000. In addition, adds and moves
simply involve moving and adding clocks.
How is Valcom's wireless technology unique?
Our mesh network technology allows each clock to repeat time
signals; therefore, as you add clocks to your system, you are
simultaneously increasing the extent of the time transmission network.
Why is Valcom's wireless system so
accurate?
Our V-WMCA wireless master clock transceiver automatically synchronizes
to an atomic time source via the Ethernet.
What is the quality of the Valcom clocks?
All Valcom clocks are designed to the highest standards and are
routinely used in all types of environments, from office buildings to
K12 facilities to harsh industrial environments.
Why should I purchase wireless clocks from
Valcom?
Valcom is one of the industry's leaders in industrial and K12 clock
systems. We have long provided time solutions for managing medium
to large groups of people.
What makes the system so easy to install?
The installation of Valcom wireless clocks is as easy as powering
the clock and hanging it on the wall.
Why is the Valcom wireless
system so reliable?
Synchronization to a National Bureau of Standard reference assures
accuracy, while the mesh network design inherently adds wireless
coverage with each clock added to the system.
How do power failures affect the
operation of the Valcom wireless clocks?
Battery operated clocks will continue to operate and provide
accurate time. 24V and 110Vac wireless clocks will update shortly
after power is restored.
Are there provisions for Daylight
Saving Time adjustment?
Our Master Clocks inherently have provisions for Daily Saving Time
adjustment. The wireless clocks simply display the time reported by the
master clock.
Where do I buy Valcom clocks?
Valcom Clocks are available from Valcom Class Connection Dealers or
from any Valcom Distributor.
How many clocks can be on a wireless
system?
An unlimited amount of clocks can be put on a wireless system.
Can analog and digital wireless
clocks work on the same system?
Yes, the Valcom wireless digital clocks and the Valcom wireless
analog clocks are fully compatible with each other.
What if I have a long distance from one
clock to another?
A repeater can be installed if the distance is too far between one
clock to another.
Do I need to have a lot of repeaters?
Since every clock in the system acts as a transmitter/receiver,
there is no need for a high volume of repeaters. Repeaters will be used
if the distances between one clock to another is significantly far.
A minimum of one V-VMC Wireless Master Clock
Transceiver or V-WMCRA Wireless Master Clock Repeater is required per
wireless clock system. Why would I use one rather than the other?
The V-WMCA Wireless Master Clock Transceiver can get time correction
info from a TCP/IP Internet connection, 59 minute correction, 58 minute
correction, National Time, Rauland and Dukane correction protocol or,
when used with certain Valcom Communications Systems, from a Valcom
V-DCPI Digital Clock Protocol Interface. It can also act as a repeater
to increase the correction signal coverage.
The V-WMCRa Wireless Master
Clock Repeater, when used with certain Valcom Communications Systems,
can get time correction info from Valcom digital (from a V-DCPI Digital
Clock Protocol Interface or V-GPSA GPS Master Clock) or via wireless
signal reception (i.e. from a V-WMCA). It can also act as a repeater to
increase the correction signal coverage.
Valcom wireless clocks use "frequency hopping". What is frequency
hopping?
Frequency Hopping (FHS) is derived from military radio technology
where it was designed to be inherently secure and reliable under adverse
battle conditions. The V-WMCA divides the available spectrum into
multiple discrete channels. Correction broadcasts then hop around these
channels in a 'pseudo-random' sequence only using any single frequency
for a max. of 400 milliseconds. Hopping out-and-into a continuous range
of frequencies gives the communications link a better chance to avoid interference.
Can Valcom wireless clocks be used with any other master clock
system?
Valcom wireless clocks are compatible with many existing 3-wire
synch wire corrected clock systems. Contact technical support for
details.
What about compatibility with other wireless clock systems ?
Other wireless clock systems on the market are not compatible with
our advanced wireless mesh transmission technology.
What are
the options for correcting Valcom wireless clocks?
Valcom wireless clocks are compatible with many 3-wire synch corrected
systems and may be used to add on to an existing clock system.
Additionally, the wireless clocks are a perfect compliment to Valcom
MultiPath or V-2924A products or may be used for new stand alone clock
systems. In the case of stand alone clock systems, our V-D110xx clocks,
V-GPSA GPS master clock and V-WMCA Wireless Master Clock Transceiver all
feature the capability to serve as master clocks. The V-GPSA GPS Master
Clock obtains its correct time from Global Positioning Satellites and
the V-WMCA Wireless Master Clock Transceiver features the capability to
synchronize to an Internet time server. When using the V-GPSA or
V-D110xx options simply add one or more V-WMCRAs as a broadcast point.
