Frequently Asked Questions

Q. Do you ship overseas?
A. Yes, we ship worldwide.

Q. Can we get GSA Pricing on On-line purchases?
A. No. There is no way for BRG to provide GSA Pricing in our on-line shopping cart.  To get GSA Pricing contact one of our inside sales team members at 800-295-0220 or 1-316-788-2000.

Q. Must I run synchronization wires between clocks?
A. No. We offer many synchronization methods that either require no new wiring or does not require any wiring at all. The BRG Wireless clock system includes a powerful radio transmitter that can sync all clocks in any size building or complex. The wireless system supports both digital and analog clocks. An Ethernet option is also available that allows clocks to obtain time from the existing computer network. Further, Ultra-High Precision clocks are available that do not require sync wire or a master clock. We also manufacture clocks that are synchronized to the master clock over the existing power line.

Q. How do the clocks receive their power?
A. The digital clocks include an 110 VAC Adapter. Ceiling and wall clocks include an internal AC transformer. Power over Ethernet (PoE) is also available for powering digital clocks. Battery power analog clocks are also available that have a five year battery life. Many other power configurations are available, including international power configurations.

Q. What is the approximate viewing distance for digital clocks?
A. Digit size and approximate visibility as follows:

Digit Size Visibility
1.8" 40 Feet
2.5" 75 Feet
4.0" 100 Feet (high-bright model)
4.0" 200 Feet (ultra-bright model)
8.0" 300 Feet (high-bright model)
8.0" 400 Feet (ultra-bright model)
12.0" 600 Feet (ultra-bright model)

Q. How are double sided clocks mounted?
A. Specify either wall or ceiling mount. If ceiling mount, include the distance from the ceiling.

Q. How do we synchronize the clocks so they all display the same time?
A. We offer many methods of synchronizing clocks, both wireless and wired.

  • DuraTime Wireless -Wireless clock systems use a powerful transmitter clock to send the time to all clocks. No building or complex is too large. The wireless clock system supports analog and digital clocks.
  • DuraTime HP - These High precision Clock are synchronized the the US Atomic Clock at BRG and is accurate to one second over 20 years. They feature a OCXO oscillator to achieve that accuracy. These clocks don't require a master clock and they feature analog and digital clocks
  • DuraTime Wi-Fi - Using your existing Wi-Fi network the BRG Wi-Fi clocks sync time to your network time. Minimal setup is required at installation. Wi-Fi clocks are available in analog and digital formats
  • Power-over-Ethernet - PoE Clocks plug into your existing computer network in your facility. They receive power and time through your powered Ethernet switch or with a mid-span power injector. PoE clocks are available in analog and digital maodels
  • Ethernet Clocks - synchronization method connects clocks to the existing Ethernet computer network. These are availble in digital configurations.

All the methods above will allow all clocks to display the same time.

Q. If I run sync wire, what kind of wiring and distance do I need with master system?
A. A single twisted pair, low voltage, up to 4,000 Ft. may be used. An almost unlimited distance is possible by configuring clocks to repeat the sync signal. Other sync methods include fiber optic cable, Ethernet, CDMA (cell phone tower) receivers.

Q. How many clocks can I run on a system, and can I mix types of clocks (digital and analog)?
A. It all depends on the clock system that you choose to use. Each BRG Synchronized Clock System uses different sync methods.

  • DuraTime Wireless - Any number of clocks can be used as long as you have an adequte signal strength from clock to clock.
  • DuraTime HP - You can have as many clocks in the sysem as you would like because each clock faeatures the OCXO Ocillator that is accurate to one second over 20 years.
  • DuraTime Wi-Fi - Can have as many clocks in the system that your Wi-Fi network can handle based on availalbe IP addresses.
  • PoE Clocks - Any number of PoE clocks can be used in a system. But you need to have PoE switches to power them or mid-span power injectors for power.
  • Ethernet Clocks - An unlimited number of Ethernet clocks can be used within a system.

Q. What is battery back up?
A. For digital clocks, when the power fails, the display is blanked while the battery maintains the internal time for about ten years. When the power is restored, the correct time will display immediately. All control parameters are stored in nonvolatile memory that does not rely on power. Analog clocks will typically run for about five years before the battery requires replacement.

Q. How does my Time Zone clock get lettered?
A. Lettering is white vinyl and you specify reading left to right. The lettering may be removed at a later date if necessary. Optional removable lettering is available; however, because of the glossy holder, they are not as attractive as the vinyl lettering. Digital lettering is also available that can be changed at any time, and comes in a variety of sizes and colors.

Q. How do I set my elapsed timer?
A. The timer can be configured from the optional infrared remote control, wired control box, buttons located on the back of the clock, PC serial or Ethernet communications, or by connecting to optional control lines.

Q. How accurate are digital clocks?
A. GPS atomic clock receivers maintains millisecond accuracy. Stand alone clocks, using the internal correction register along with the ultra-high precision oscillator option, can achieve an accuracy of about 1 second per year.
