Pyramid 7000 Master Clock Controller with 110V Output
Description
The Pyramid 7000 master clock controller is a work shift timer designed to synchronize facility clocks while operating scheduled bells, buzzers, or horns. It serves as a central timing device for facilities that require consistent time across departments and automated signaling for shift changes, breaks, or scheduled events. Programming is performed directly at the controller, allowing stand-alone operation without software or network connection.
The controller distributes time signals to compatible Pyramid synchronized analog or digital clocks while activating connected signaling devices at programmed times. The system supports up to 300 scheduled bell or horn events and automatically adjusts for daylight saving time changes. The 110V output version includes an internal relay for operating standard AC bells or horns, allowing existing signaling devices to be reused during upgrades or replacements. The master clock maintains timing accuracy after power interruptions and restores normal operation automatically when power returns.
This system is commonly installed in manufacturing facilities, warehouses, schools, and multi-department environments where maintaining a single time reference improves coordination. The Pyramid 7000 is typically used when replacing older mechanical bell timers or when expanding to synchronized clocks while keeping bell signaling controlled from one device.
Compatibility and Usage
- Pyramid 7000 master clock and work shift timer platform
- 110V relay output for bells, buzzers, or horns
- Synchronizes compatible analog and digital wall clocks
- Supports up to 300 programmable timed events
- Automatic daylight saving time adjustment
- Expandable for additional clocks or signaling devices
FAQ
Can the Pyramid 7000 run clocks and bells at the same time?
Yes. The controller synchronizes clocks while activating scheduled bell or horn signals.
How many clocks can be connected?
Up to approximately 200 compatible synchronized clocks can be supported depending on installation layout.
Is this used to replace older bell timers?
Yes. Many installations replace mechanical timers to gain programmable scheduling and synchronized time control.

Pyramid 7000 scheduled work shift timer program example
Imagine everyone going back to work on-time at the end of breaks, end of lunch.
We made this example, many people print it out and make their own, using this as inspiration.
Notice that there is a three-minute warning for the end of lunch. A five-minute warning for the end of the day.
This works. Give it some thought.
Print this out, write up your own. Make a short one second ring for the warnings.
Pyramid 7000 and our network bell systems do this. The Lathem Sonachron does not.

Information you will not find anywhere else...
You can theoretically run 32 bells, plus 16 analog clocks, and unlimited digital clocks off of the 7000, And 32 low voltage Pyramid bells off the 5300. It's not that easy. So we did the research.
Pyramid digital clocks self-amplify the time signal and forward it to the next clock via the company's proprietary BCD cable. You must have a digital clock (or a 5300 signal amplifier) every 200' for this to work. BCD cables connect with Pyramid's again propretary "Y" connector - which we will supply to you as many as you need at no charge (nickels and dimes).
Pyramid's 13" dial face "analog" clocks do not have this signal amplification feature. So, every 200' or 8 clocks - whichever comes first - you need to add/purchase a PTR5300 power supply. This amplifies the time signal and allows you to extend the range.
Bells: Pyramid low voltage bells are 24VAC and draw a very small amount of amps. Somewhere in the range of 100M/a. 1000M/a is 1 Amp. When you hit 250' or so, and several bells, it will start to get quiet. We now offer a power booster that you would connect inline, adding a fresh 1 amp and 24volts DC to run additional bells as needed.
Work with people who obsess over the details - so you don't have to.
Tone Generator Controller
If this is for a tone generator, we can make it cold contact instead of 110V output. Just let us know.
