MASTER CLOCKSBogen is proud to introduce its Master Clocks. The standard models come loaded with many helpful features including a user friendly built-in web interface for master clock settings and monitoring, as well as many optional features to choose from, allowing system flexibility all wrapped in an elegant and stylish housing.
Bogen’s Master Clock is the center of a synchronized clock system. The master clock’s primary function is to receive accurate time and distribute that time to all of the secondary clocks throughout a facility. The master clock is programmed to frequently send out a time signal in order to prevent the clocks from drifting. This will allow all of the secondary clocks in the facility to always display the same time on every clock within a system.
The Bogen Wireless Clock System begins with Bogen’s Master Clock. The BCMA 2000 Series is our standard master clock model with a front LED display and two push buttons for basic system programming. The BCMA 3000 Series comes with a front LED and LCD display as well as a keypad to allow for advanced programming. The BCMA 3000 model may also be offered with four or eight programmable relays (zones) to control third party systems via a contact closure (such as a school bell system). The BCTP series Master Clocks add NTP server and IP capability to the BCMA feature set.
All of Bogen’s Master Clocks come with a built-in web interface to allow easy setup and programming from any computer in the facility via LAN. By default, the master clock receives the time data via the internet from up to ten preprogrammed (user changeable) third party NTP Servers for superior accuracy and redundancy. The master clock is also offered with an optional GPS receiver as an additional source for receiving accurate time. In addition, the master clock has a built-in real-time clock and can send an email alert when communication with the accurate time source(s) is lost.
THE BOGEN ADVANTAGE
Fully functional Web Interface – Bogen’s web interface allows the system administrator to have total control of the master clock’s settings through an easy-to-use built-in web interface. This will allow the system administrator to control settings such as Daylight Saving Time, E-mail-alerts, NTP server settings, and so much more from any computer on the same network.
Automatic Daylight Saving Time Update – Depending on the size of a facility, it would be a difficult and time consuming task to adjust each clock when Daylight Saving Time occurs. With a Bogen Master Clock controlling the system, there is no need to worry about adjusting the time on each clock by hand, as the clocks will automatically update themselves. This feature not only saves time, but also saves money in maintenance fees over the life of the system.
NTP Server Redundancy – To ensure complete accuracy within a system, Bogen’s Master Clock allows a user to input up to 10 NTP server IP addresses for redundancy purposes. If communication with one NTP server is lost, Bogen’s Master Clock will automatically move to the next NTP server IP address that is on the list.
E-mail Alerts – A user is able to receive automatic e-mail alerts when specific changes have been made to the master clock or if communication with the accurate time source has been lost. This feature allows a user to always be aware of the status of the master clock.
Interfacing with Other Systems – Here at Bogen, we want to make integrating our clock system within a facility as simple as possible. Bogen’s master clock is capable of interfacing and receiving various time protocols such as 58 minute correction, 59 minute correction, National Time / Rauland correction, or Dukane protocol.
System flexibility – A master clock equipped with a transmitter can provide time to both wired clocks, as well as to wireless clocks providing the wired clocks with the time signal in a wired manner, it is also transmitting the time signal wirelessly. Bogen’s Synchronized Clock System also provides the flexibility to mix between analog and digital clocks offered in different shapes and sizes.
How Does The Master Clock Receive Time?
The master clock can receive the accurate time mainly from two sources:
- NTP Server – A standard feature in each and every master clock model
- GPS Receiver – An optional feature
The master clock can also receive the time by:
- Once-a-day contact closure from a third party device
- Interfacing with existing clock systems (58 minute or, 59 minute protocol, National Time / Rauland or Dukane protocol)
Additionally, the master clock has its own internal real-time (quartz) clock. In the event that communication with the accurate time source has been lost, the system will still be synchronized based on the real-time (quartz) clock, until communication with the accurate time source has been restored.
Receiving Accurate Time From an NTP Server
All Bogen Master Clocks receive accurate time from NTP servers as a standard feature. A master clock may receive its time either from an external NTP server (third party NTP server) or via an in-house NTP server (if there is one in the facility).
Receiving Accurate Time From Third Party NTP Servers
Sources of NTP time include government facilities, colleges and universities, and various corporations. Such institutes allow a free connection to their NTP server via the Internet as a source of accurate time. Bogen Master Clocks are designed to store up to 10 NTP server IP addresses for redundancy. This means that if communication with the first NTP server has been lost, the master clock will automatically attempt to receive accurate time from the next NTP server in the list. This unique feature provides reliability and redundancy to the system. Bogen already provides the master clock with 10 NTP server IP address inputs to get accurate time from, but at any time you are able to change all 10 default NTP server IP addresses to ones that you prefer.
Master Clock | BCMA 2000
All of Bogen’s Master Clocks come with a built-in web interface to allow easy setup and programming from any computer in the facility via LAN. By default, the master clock receives the time data from third party NTP servers via the internet. The master clock is also offered with an optional GPS receiver as an additional source for receiving accurate time. In addition, the master clock has a built-in real-time clock and can send an email alert when communication with the accurate time source(s) is lost.
Master Clock | BCMA 3000
- Includes all of the BCMA 2000 Series’ capabilities
- LED and a backlit LCD display for a clear, accurate read out
- 2 x 8 rubber button keyboard for easy programming
- Can command digital clocks to display “Bell” at user defined In this case the master clock must have at least four relays (not applicable when using a sync-wired system or an IP system)

Master Clock | BCTP 7000
The BCTP 7000 also encompasses a fully functional web interface for controlling the master clock from any computer on a network or via a crossover cable. As an optional feature, the NTP 7000 has the ability to have its own (S)NTP server that other devices can point to in order to receive time via (S)NTP.
The BCTP 7000 Series includes all the standard features listed with the BCMA 2000 Series, as well as the capability of acting as an NTP server and provide NTP time to other IP devices in the facility.
Master Clock | BCTP 8000
The BCTP 8000 also has a variety of additional options that can be purchased separately, such as the ability to have its own (S)BCTP server that other devices can point to in order to receive time via (S)BCTP. With the ability to handle up to 8 auxiliary zones (optional), the BCTP 8000 is able to handle a variety of applications such as bell scheduling, lights, etc.
