Time systems & bells
Time servers and master clocks
In a time system, a master clock takes the exact time from a reference source and distributes it to every clock in the building, which then synchronise automatically. Choosing a system comes down to two decisions: where the master clock gets the time (radio or GPS) and how it passes it on (wireless DHF, coded cable, pulse or an NTP network).
Overview
A synchronisation system always has two parts: a reference source that supplies the exact time, and a distribution method by which the master clock sends that time to every slave clock in the building. The slave clocks receive the time message, compare it with their own time base and correct themselves automatically; if the signal drops, they keep running independently on their own quartz time base until it returns.
Types & options
Netsilon
Bodet Netsilon time servers supply the exact time over the standard NTP and PTP protocols, directly inside the IT infrastructure — for computers, IP surveillance cameras and access-control systems. Three models: Netsilon 7, an NTP time server, and Netsilon 9 and 11, PTP GrandMaster clocks and NTP servers.
Sigma
The Bodet Sigma master clock sends the same time base to the whole network of analogue, digital or LCD clocks, and also schedules bells, lighting, heating, air conditioning and access control. It mounts on a wall or in a rack, in four versions: SIGMA-H, SIGMA-P, SIGMA-C and SIGMA-MOD.
Radio and GPS antennas
The antenna brings the exact time to the master clock: by radio, from the MSF, FI or DCF transmitters, or by GPS, from the network of 24 satellites, with automatic summer/winter changeover. Sigma master clocks accept DCF, GPS, GLONASS or Galileo antennas — the source is chosen to suit the site and the reception available.
