A minimum of one
V-VMC Wireless Master Clock Transceiver or V-WMCR Wireless Master
Clock Repeater
is required per wireless clock system. Why would
I use one rather than the other?
Valcom wireless clocks use "frequency hopping". What is frequency hopping?
Can Valcom wireless clocks be used with any other master clock system?
What about compatibility with other wireless clock systems ?
How much area will a
V-WMC Wireless Master Clock Transceiver
service?
With Valcom’s unique mesh transmission design, the
area covered by the actual transceiver is not important. Each Valcom
wireless clock added to your system provides an additional broadcast
point. In an actual installation, by maintaining no more than 60 feet of
spacing between clocks, coverage can easily be provided to any size
facility. As far as transmission through open space, between buildings
for example, users can expect up to 6000 feet of coverage.
How frequently do the batteries need to be replaced in the battery
operated wireless clocks?
Battery life of up to 5 years may be expected in ideal conditions.
Factors contributing to battery life include the grade of battery used
(Duracell Procell batteries are recommended) and the correction signal
strength in the area where the clock is mounted.
How often do the wireless clocks update?
110V and 24V clocks update every minute. The battery-operated clocks
receive for 30 minutes following initial power up and then for 5 seconds
each 4 hours (12, 4 and 8 o’clock). Upon successful reception, they
retransmit the correction signal to adjacent clocks. If signal is not
received, the battery operated clocks increment their receive time with
each attempt until successful reception occurs.
How far can the clocks be spaced from each other for successful
transceiver operation?
Although many factors contribute to the effective
range of transmission, successful transceiver operation may occur at up
to 150 foot direct, or 60 foot adverse, spacing.
Can the clocks correct via a GPS signal?
Our wireless clocks synchronize to our master clocks – not directly to
GPS. We do offer a GPS master clock that
may be used as a time base. The clocks simply display the time reported
by the master clock.
How can I determine if the wireless clock is
receiving signal?
Built in diagnostics allow users to determine both the presence and
quality of signal available in the clock’s location.
Will the
wireless clock system cause interference with any of my other wireless
devices?
No. The clock’s use of frequency hopping technology eliminates any
possible interference.
Is there a cost advantage over wired clocks?
The cost savings of not having run wire to the clocks can be very
significant –
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-WMC 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.
What can be expected as far as battery life is
concerned?
With premium D Cells (like Duracell Procells) and good reception,
battery life should meet or exceed a 5-year life.
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 to be used 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-WMCR Wireless Master Clock Repeater is required per
wireless clock system. Why would I use one rather than the other?
The V-WMC 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-WMCR 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-GPS GPS Master Clock) or via wireless
signal reception (i.e. from a V-WMC). 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 (FHSS) is derived from military radio technology
where it was designed to be inherently secure and reliable under adverse
battle conditions. The V-WMC 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 remedy
any transmission errors that may be caused by 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-GPS GPS master clock and V-WMC Wireless Master Clock Transceiver all
feature the capability to serve as master clocks. The V-GPS GPS Master
Clock obtains its correct time from Global Positioning Satellites and
the V-WMC Wireless Master Clock Transceiver features the capability to
synchronize to and Internet time server. When using the V-GPS or
V-D110xx options simply add one or more V-WMCRs as a broadcast point.
