Movements and synchronisation:
Quartz movement
► The clock is totally independent, the time information comes from its own time basis.
► Automatic summer/winter time changeover.
DHF movement
► The clock is radio-synchronised by a DHF transmitter.
► Automatic summer/winter time changeover.
FI or DCF Radio synchronised movement
► The clock is independent, the time information comes from its own time basis which is
rectified, in case of drift, by comparing it to the FI or DCF transmitter signal.
► The radio synchronisation permit to display the time with perfect accuracy.
► Automatic summer/winter time changeover.
IRIG B/AFNOR coded time receiver
► The coded time distribution consist in transmitting a complete time message each second :
the setting on time of the receivers is realised automatically and speedily as soon as they
are connected on the clock line.
► The IRIG B/AFNOR coded time does not transmit interference and is insensitive to other
electrical interference.
24V minute impulses receiver movement
► The receiver clocks are connected to a distribution line and activated by means of
electrical impulses transmitted every minute by the master clock.
NTP PoE receiver
► A NTP time server sends UTC time periodically on the Ethernet network. The clocks pick up the time
messages, apply the relevant time zone and set themselves automatically to local time.
The NTP server must have a transmission (Poll) period of less than 128 seconds.
PoE power is supplied to the clock through the network via the RJ45 plug.
► Wall support (supplied)
► Table support
► Double sided bracket for wall or ceiling mounting
► Double sided bracket for wall or ceiling mounting (long length)
► Single or double sided bracket specific length for wall or ceiling mounting
(Please specify on the order the fixing mode (wall or ceiling) and the length
between the top of the clock and the fixing point).
► Support for very low voltage power supply
► Embedded TBT (very low voltage) power supply (Capacity: 20 clocks)
► Wall plug-in TBT power supply (capacity: 20 clocks)
