Pyramid 7000 Work Shift Timer and Master Clock Controller
Description
The Pyramid 7000 work shift timer is a master clock controller designed to operate scheduled bells, buzzers, or horns while maintaining synchronized time across multiple clocks. It is used where a single time reference is required across departments, allowing shift changes and scheduled events to occur at the same time throughout a facility. Programming is performed directly at the controller, allowing stand-alone operation without software or network connection.
The controller distributes time signals to compatible analog or digital wall clocks and activates connected 24VDC bells or horns at programmed times. The system supports up to 300 scheduled events and can synchronize large clock systems from a single controller. Automatic daylight saving time adjustment and internal program retention allow the system to maintain accurate operation after power interruptions. The low-voltage signaling design allows clocks and signaling devices to operate from a centralized timing source while simplifying expansion as additional devices are added. :contentReference[oaicite:0]{index=0}
This type of system is commonly installed in manufacturing facilities, warehouses, schools, and large work areas where manual signaling is impractical. The master clock removes time differences between departments and ensures audible alerts and visual time displays remain synchronized. The Pyramid 7000 is typically used as the central timing device when both clock synchronization and scheduled signaling are required in the same installation.
Compatibility and Usage
- Pyramid 7000 master clock and work shift timer platform
- Controls scheduled 24VDC bells, buzzers, or horns
- Synchronizes compatible analog and digital wall clocks
- Supports up to 300 programmable timed events
- Low-voltage signaling for expansion and system growth
- Common in manufacturing, schools, warehouses, and campuses
FAQ
Can the Pyramid 7000 run clocks and bells at the same time?
Yes. The controller synchronizes clocks while also activating scheduled bell or horn events.
How many clocks can be connected?
Up to approximately 200 compatible synchronized clocks can be supported depending on wiring layout.
Is this a replacement for older mechanical bell timers?
Yes. Many installations replace older timers to gain programmable scheduling and synchronized time control.

Standard one circuit system
- Powers up to [35] 6" (or quieter 8") Pyramid low voltage bells, max distance 300'
- Synchronize up to 200 digital, or 8 analog wall clocks, max distance 300'

Specifications:
- It's the size of a paperback book 6“ high, 5 1/2“ wide, 2“ Deep
- 24VDC - That's why we designed our custom module to run 110 volts
Plus:
It can run up to 200 digital or analog “Child“ shop time clocks - so that everyone knows what time it is and have no excuse to wander around during the day, wasting time (and your money). Visible up to 250' away. Large 4" bright red LED numbers.
We can make this run AC, click here to see how.
It can also take over YOUR EXISTING bell and buzzer system. Replace that old controller with this. Call us first.
Why do business with Employee Time Clocks?
1) We have over 600 of these systems installed (as of December 9, 2020)
2) We are not copying a catalog to the website, we know this equipment inside and out.
3) We have actual installation and on-site problem solving experience
In this business, we are unique, and that is why you should call us.
This is an example we made.
Step 1: Make a template like the one below.
Step 2: Fill it out. You can set the system to ring up to 72 times a day.
You set how long it rings for each ring event.
Look closely at our example, there are two minute warnings.

Information you will not find anywhere else...
You can run 16 bells, plus 16 analog clocks, and unlimited digital clocks off of the 7000, And 16 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 proprietary "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.
