Synchronize System Clocks

How to choose a system of distribution of time?

Distribution of an hour is to fly a network of clocks in order to ensure the same time for all buildings. The hourly is transmitted by a clock mother radio synchronized, and setting the clocks time is automatic.

The FI, DCF or GPS time synchronization ensures permanently a time accurate and reliable, as well as time changes / winter.

Wireless time distribution

Wireless time distribution allows to synchronize clocks or radio relay network in one or more buildings without the need to connect cable clocks defined on Dictfurniture.

The clock emits the AFNOR standard timecode via a radio transmitter. Receiving clocks capture the hourly and syncs automatically.

Additional DHF relays allow to receive the programming of devices to activate as well as the delenchements of the rings for the schools.

Key benefits:

  • The DHF is the ideal solution for a unified time distribution.
  • Removal of the cables with a significant saving on installation costs.
  • Freedom of establishment of clocks, without apparent cable (with batteries like the Cristalys clocks).
  • Equivalent to a wired installation reliability.


  • Use public or industrial buildings, schools…
  • Rehabilitation of premises, public or industrial, extension of existing facilities.
  • Installation multi-batiments: University campus, large factories, sites with road crossing.

Distribution of wired time

A main clock (clock), led and synchronizes the receiver clocks, the clock is usually synchronized by radio on a hourly transmitter DCF, France Inter, or GPS.

In a wired network, receiving clocks can be driven by impulses or a coded time signal from the clock.

Distribution of time to impulses

A signal is sent by impulses polarized every minute, or second. This technology is suitable for small facilities where there is a limited number of secondary clocks and a short distance from wiring.

Key benefits: economic solution for a small hourly distribution with clocks to needles.

Coded time distribution

Distribution of time time coded, called code AFNOR, transmits a complete hourly message on a two-wire line. The time and date of the secondary clocks is automatic. This type of distribution is mainly used in large facilities (airports, railway stations) with a long distance between the secondary clocks.

Key benefits: ease of implementation, installation and maintenance costs. Well suited to networks of digital clocks.

Distribution of time NTP

The time synchronization NTP (network time protocol) is a standard of computer communication to synchronize a computer, a computer network or automation devices. This synchronization is performed by a server NTP Sigma MOD having its IP address and sending on all related products the same timecode in hour UTC.

Bodet offers a full range of NTP clocks in digital or analog display (LCD or LED) according to the needs of the customers. Each clock is individually set for the display of local time and can run on its own time in the event of the NTP message base.

Hourly distribution NTP has no limit in clocks or computers connection ability. Each clock is supplied via the network (PoE) either in individual power supply (230V or TBT).
