The calendar clock has the ability to show the day-of-week and month in a single language or using two or three alternating languages from a selection of 22. The display brightness can be manually pre-set or controlled automatically.
  450A, 452A, 453A and 454A series calendar clocks have four additional, user selectable date display modes to show alternate date formats, julian date or day-of-year or the week number:

LanguagesThe day-of-week and month information can be displayed using a single language or two or three languages alternating languages at a user selected interval. The available languages are: Catalan, Czech, Croat, Danish, Dutch, English, Faroese, Finnish, French, Galician, German, Hungarian, Italian, Norwegian, Polish, Portuguese, Russian, Slovak, Slovenian, Spanish, Swedish, Welsh.
Internal clockThe internal time base is pre-programmed for leap years, and statutory seasonal time changes.
Case construction 45x and 46x digital calendar clocks are available in five different case styles with versions suitable for wall mounting, double or single sided ceiling suspension or flush mounting in a solid wall or control panel. The high quality cases are manufactured from anodised or painted aluminium extrusion.
Power supply45x and 46x calendar clocks will operate from 100-250v 50/60Hz power supplies for global use. Operation from 24v dc supplies is available at extra cost. The local voltage and operational location should be specified at time of order to ensure that the unit is supplied with the appropriate mains connection.

timekeeping & synchronisation to top of page
45x and 46x series calendar clocks will operate as stand-alone day-date clocks or may be synchronised from a wide range of external time references.
Stand-alone operation When used in stand-alone configuration the calendar clock maintains time keeping from a high stability internal crystal oscillator. The clock is pre-programmed for leap-years, and can be user programmed for the appropriate local automatic seasonal time-change.
Standard synch. modes
  • w482® time code
  • alternate and single polarity 12-48v impulses
  • MB serial & MOBAline® time codes
  • DCF & MSF radio time codes (requires a 484 series radio synchronisation receiver)
  • GPS satellite time signals (requires 488 series GPS time synchronisation sub-system)
Optional synch. modes
  • EBU/SMPTE time code - requires optional 404.E internal interface card
  • IRIG-B and afnor NFS 87 500 time codes - requires optional 404.I internal interface card
  • NTP option allows syncronisation via an ethernet interface from a remote master clock or time source
Master mode 45x and 46x series calendar clocks can act as a master to control up to ten 400A series clocks and calendar clocks as secondary clocks when fitted with an internal 404.M interface module.
