RGB Clock Systems

Product Description

The clocks made in the Prestige Line technology are compact devices of high configuration capacity. The intuitive user's menu allows you to fully customise the type of the displayed information. The devices have non-volatile memory, which stores the entered settings. The set consists of a clock, mounting hardware, a remote control or a LAN communication module. The clock may be optionally equipped with a satellite time synchronisation module, a temperature probe, an industrial acoustic signalling device.

ZA Clock

The clock enables:

  • Adjusting the time of displaying parameters
  • Adjusting the date format
  • Automatic brightness control
  • Fixed time display blanking
  • Automatic satellite time synchronisation (option)
  • Automatic NTP time synchronisation (option)
  • Automatic time change from the standard time to the daylight saving time and from the daylight saving time to the standard time
  • Displaying temperature (℃, °F)
  • Displaying time in the 12/24-hour format
  • Time countdown - stopwatch function

We offer devices of different digit heights: 5cm, 10cm and 20cm. Such diversity of the glowing digit sizes enables adjusting the device to the mounting location and to the user's needs.


  • Inside buildings: production halls, receptions, swimming pools, workplaces, halls, corridors, waiting rooms, schools
  • Outside: over building entrances (as an element of the façade raising the prestige), open sports facilities
  • Stations, platforms, airports, passenger information, logistics centres
  • Inside public transport vehicles
  • In pylons, welcome signs, and in advertising and information totems

All clocks are resistant to adverse weather conditions (IP66) and have an anti-reflection surface. The comparison of the device housing technologies is shown below. Mechanical differences between the housing technologies allow you to choose an option appropriate for the mounting location and the method of installation.

Series Comparison

The devices of all series offer identical functionality, but differ in the time presentation format and the housing making technology. The comparison of the device housing technologies is shown below. Mechanical differences between the housing making technologies allow you to choose an option appropriate for the mounting location and the method of installation.

Time Synchronisation

Time in the clocks can be set manually by the user or using the function of automatic time synchronisation – available in two options:

1. GPS satellite time synchronisation

Although the GPS has been created for positioning (i.e. defining the location), it can also be used for other purposes. In the received GPS signal, there is embedded information about the current time and date. This time is very accurate because it is determined according to atomic standards. It may be slow or fast by just one millionth of a second per month. For the proper operation, it is required to place the receiver in the location providing the "visibility" of the sky.

The advantages of the GPS synchronisation:

  • Provides precise time synchronisation from the GPS satellites based on atomic standards
  • Does not require any configuration
  • Does not require the Internet connection
  • Operates in every location on the Earth
  • A LED signalling proper signal reception is embedded in the receiver

To take advantage of the satellite time synchronisation, you should equip the clock with the optional GPS Receiver.

2. NTP time server client

NTP (Network Time Protocol) – is a communication protocol supporting precise, stable and safe synchronisation of clocks with any time server through the computer network. A great advantage of this solution is the possibility of simultaneous synchronisation of many devices. The synchronisation may be executed:

  • From your own local time server – the Internet access is not required
  • From a public remote time server – the Internet access is required

Every clock can be configured as a local NTP time server – as described below.

The advantages of the NTP synchronisation:

  • Provides precise time synchronisation with NTP servers
  • Possibility of simultaneous synchronisation of many clocks from the same server
  • Operating five different time servers (1 primary and 4 alternative) provides reliable synchronisation
  • Changing the time server from the primary to an alternative one is carried out automatically when a failure is detected

The NTP time synchronisation is carried out via the Ethernet (the interface is included in the standard equipment of every clock).

Function of a local NTP time server

Every clock of the ZA/ZB series may be a central clock (MASTER) which, in the LAN, will provide the time source for other clocks (Slave). In consequence, it is easy to create a clock system in which the central clock can upload time from different sources, such as: a GPS receiver, a public NTP server or its own internal clock. Providing synchronised time to all clocks guarantees that everybody uses the same time source. It is extremely important for workplaces, production halls, schools, stations, platforms, etc.
