Which Synchronized Clock System fits your needs?

BRG offers three types of synchronized clock systems.  HP, PoE, and Wireless. 
All three methods provide accurate synchronized time for the life of the clocks.


DuraTime HP (High Precision)
Pros Cons
  • Highest Reliability

  • Synchronized Time Without the need for Wires or Radios

  • Displays the same accurate synchronized time as wired or radio controlled systems, but far easier to install and maintain

  • Clocks are factory synchronized with the time standard

  • Each clock stands alone and does not rely on communications wires or a continuously available time source

  • No GPS or other antennas required.
    Stand-alone clocks are available that support alarm schedules

  • Lower cost than most PoE or Wireless solutions

  • Mains and Low Voltage models available

  • Clocks cannot be controlled from a central source without adding Wiring or Radios communications, but central control is typically unnecessary

  • No battery powered models available

 

PoE (Power over Ethernet) (computer network)

Pros Cons
  • Medium reliability

  • One network cable supplies both power and time data to the clocks

  • Provides accurate time only as long as the communications and time source is correct

  • Complicated to configure and maintain

  • Requires skilled IT people to install and maintain

  • Changes to the computer network can disable communications required for synchronization

  • More expensive than most other synchronized clock solutions


DuraTime Wireless (2.4 GHz Mesh Radio)

Pros Cons
  • High reliability

  • Redundant master clocks are supported for enhanced system reliability

  • Every clock receives and repeats the sync signals to provide coverage for any size facility

  • Multiple, mesh communications paths provide high reliability

  • Battery powered clocks operate up to 15 years between battery changes

  • Battery powered clocks are unaffected by power glitches and disruptions

  • Clocks continue to operate even if one or two batteries fail

  • Master clock supports alarm schedules

  • Master clocks include Ethernet NTP time source standard

  • Wireless GPS receivers available

  • Radio signal may not penetrate some areas

  • Distances (300 feet) between clocks may exceed communications path

  • Each separate building usually requires a lower power master clock

The above synchronized clock solutions can be combined.  For example, PoE clocks could be used for all indoor clocks and HP clocks used outdoors or other areas where the network is unavailable.  Or, wireless clocks could be used above ground and HP clocks used in the basement and other areas where the radio signal is unavailable.
