FAQ (Frequently Asked Questions)

1. What does ISO9001:2000 and AS9100B Certified mean?

ISO 9001 is a quality management system and is intended for use in any organization which designs, develops, manufactures, installs and/or services any product or provides any form of service. It provides a number of requirements which an organization needs to fulfill if it is to achieve customer satisfaction through consistent products and services which meet customer expectations.

The latest version is: 2000. AS9100B is based on ISO 9001:2000, but with more than 75 additional requirements specific to aerospace, AS9100 provides suppliers with a comprehensive quality system focused on areas directly impacting product safety and reliability. AS9100 is rapidly becoming a prerequisite for doing business, as many aerospace original equipment manufacturers (OEMs) only work with suppliers that are registered to the applicable AS9100 standard.

2. What are the benefits to me when complying with I ISO9001:2000 and AS9100B?

  • Focuses the organization upon the key characteristics of their products and services, as well as the key requirements of the customer
  • Supports compliance to the globally accepted quality standard supported by regulatory bodies
  • Increases the organization's opportunities, acceptance and quality within the global aerospace supply-chain
  • Improves product and process quality and efficiency by reducing variation
  • Reduces quality costs by eliminating waste and reducing risk
  • Requires not just meeting customer requirements, but also customer satisfaction and customer focus
  • Requires not just corrective/preventive action, but also continual improvement
  • Requires not just stand-alone procedures, but process-based quality assurance

3. What is the typical delivery time?

We will work with your reasonable requirements to provide your clock within your deadline. Most clocks are  made to your specification.

4. How do you light clock dials?

Backlit, Frontlit, LED’s

5. What is the motion of your clock movements?

The clock movements are pulse-driven. When the clock, whether analog or digital, is connected to a master clock, in a wired or wireless sytem, their mechanisms are driven by a pulse either sent, every second, every thirty seconds or every minute depending on the type of clock.

6. What is a master clock?

A master clock is the clock that provides synchronized time to all the other remote clocks. It is normally connected to a GPS antenna which then provides accurate, synchronized time.

7. WWVB versus GPS, which is more accurate?

WWVB is a radio signal/transmitter that continually broadcasts the time and date at a frequency of 60kHz from the National Institute of Standards and Technology (NIST) in Fort Collins, Colorado. Many of the clocks available commercially are calibrated by WWVB. The WWVB signal is accurate but is limited in certain situations. Because reception of radio signals vary, the performance of the clock will also vary. The clock will also be affected when mounted within a commercial building as it can be influenced by the materials with which it is constructed.

Additionally clocks should not be made of any sort of metal as that will also influence the signal received from WWVB. The distance from the transmitter and weather patterns can also affect the accuracy of the clock time. Most WWVB clocks search for a signal 4 times per day and are only likely to get a signal once during the night or early morning when there is little other interference.

GPS however provides six synchronizations during the day and is able to be used in commercial applications. The GPS signal is not as affected by weather patterns or buildings. The system also automatically takes care of the correcting of clocks after system or power outages as well as daylight saving changes. GPS uses 24 satellites which have accurate clocks to provide the time signal. The satellite clocks get their time signal from the NIST as well.

Therefore GPS is more accurate than traditional WWVB.

8. Is the clock able to be reset from a remote location?

The Brandywine system can include remote re-setting as an option in your system.

9. Does the clock auto-correct for daylight savings?

Yes, it can if connected to a master clock as part of your system..

10. Can all clocks in the building be connected?

Yes they can, either through a wired or wireless system.

11. Is the clock flush mounted or is it through the wall installed?

It can be done either way depending on the design. It is always better to have the clock motor mechanism protected from the weather and therefore through the wall installation is preferred on outdoor tower clocks.
