45x and 46x series
calendar clock, digital calendar and day date clocks are
manufactured and tested to provide totally reliable service over many years in command and control facilities,
conference and reception areas, offices, public places and other areas were a precise and clear display of time and date is required.
Time and date and information is displayed using high quality, colour and brightness matched
red, yellow, green or blue LED characters. 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:
julian date day-month
week number day-month
The day-of-week and month information can be displayed

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.
The internal time base is
pre-programmed for leap years, and statutory seasonal time
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.
45x 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.
Standard surface mounting cases supplied with multi-angle wall mounting brackets
Flush mounting case with a 6mm wide (0.25") front retaining bezel and supplied with adjustable rear mounting fixings
for mounting in a control panel with rear access
Flush mounting enclosure with a 6mm wide (0.25") retaining bezel and supplied with a steel mounting
box for fixing in a solid wall
Single sided clock for ceiling suspension, with one or two support tubes for a drop of up to 1m
- (39"). Support tubes for longer drops are available at extra cost
Double sided clock for ceiling suspension, complete with supports for a drop of up
to 1m - (39"). Support tubes for greater drops can be supplied at additional cost
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
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
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.
450A.05, 451A.05 and 460A.05 series calendar clocks will
operate from a 110v or 230v 50/60Hz ac power supply
depending on order specification. The power consumption
is ‹0.2A @230v. DC operation from 12, 24 or 48v supplies
is available as an extra cost option.
