Time synchronisation
The displayed time of the clock is set by automatic time synchronisation from GPS satellites.
95% of our customers choose GPS satellite time synchronisation as it makes the clocks effectively maintenance-free.
GPS has the following advantages:
- provides precise time synchronisation from the GPS satellites based on atomic standards,
- does not require any configuration (plug and play),
- does not require an Internet connection,
- operates worldwide (subject to reasonable view of the sky),
- gps module has integral LED to confirm proper signal reception.
Your clock will be delivered with a small GPS receiver box ready-installed. It is necessary to place the receiver in a location providing “visibility” of the sky. The GPS receiver is connected via included 10m cable for indoor clock installations the GPS receiver can still be installed outdoors.
Mounting
The ZA/ZB clocks are supplied with a steel mounting bracket for wall or cabinet mounting.
Hanging mounting (typically on chains) or perpendicular mounting (railway style) is available as an add-on option – please email or Request a Quote for further details.
For this 200mm 4 digit clock there is a vertically mounted bracket at each end. There are four 6x10mm oval holes at centres of 180mm (vertically) and 535mm (horizontally) for fixing with pan-head screws or bolts (not supplied).
4 blanking plugs need to be popped-out to give access to remove the 4 bracket screws so the 2 brackets can be removed for installing.
(Dimensions stated above are for guidance and subject to revision without notice.).
Getting started
Your new clock is supplied with a fitted UK mains plug and the clock can be up and working in seconds.
If the GPS receiver module is pointed to a patch of sky then in less than a minute the correct time will be displayed.
If you require a clock to be viewed from over 150m we would recommend our extra large outdoor digital clocks. Offering the same high standard of build from RGB Technology and boasting digits of 400mm these clocks are ideal when viewing from distances over 150m.
