Compumatic MP550 Time Clock with Two Synchronized Buzzers
Description
The Compumatic MP550 two buzzer kit is an electronic punch clock system designed to record employee time while activating two buzzers at scheduled times. It combines the MP550 front-loading time clock with a factory-installed signal kit to automate shift changes, breaks, and lunch periods without requiring separate timers, software, or network connections. Scheduling and signal control are handled directly inside the clock, allowing stand-alone operation once programmed.
This configuration includes the MP550 time clock, internal signal board, external power supply, wiring, and two 110V vibrating buzzers for synchronized signaling. When programmed, the clock activates both buzzers simultaneously, improving sound coverage in larger or higher-noise work areas. Signal duration can be adjusted through internal programming to allow short warning signals or longer shift-change alerts. The signal kit provides external activation through the clock’s timing controls, eliminating the need for separate relay timers.
The MP550 platform is commonly used where a simple time card workflow is preferred but audible signaling is required to maintain consistent scheduling. Typical installations include shops, warehouses, maintenance departments, and production environments where employees may not always be watching the clock. Using the time clock as the signal controller keeps time recording and signaling tied to a single timing source and reduces system complexity compared to separate timers and control equipment.

FAQ
Why use two buzzers instead of one?
Two buzzers improve coverage in larger areas or environments with higher background noise.
Does the MP550 require a computer to run the schedule?
No. All scheduling is programmed directly at the clock.
Can the system still be used as a normal time clock?
Yes. The MP550 continues to function normally for employee punches and document stamping.

These Systems Pay For Themselves In Just Two Weeks.
Example:
You are in manufacturing, you have 10 or more employees.
They drag out break and lunch time by 2 to 3 minutes, every day, two breaks, one lunch a day. Worse yet, you have "smokers"
When the lunch ends, someone has to shout "Back to work!"
Stop the drama, the bell becomes "the bad guy." Not you or a manager.
Install a simple - or advanced - bell or buzzer system, the bell becomes that "bad guy."
They won't miss a break, they will take lunch on time, they will start when they should, they will come back, like trained people, when they are supposed to.
You will collect back, using very conservative numbers, a minimum of 4 minutes per day per person.
Doesn't sound like much, you would be wrong.
Using extremely conservative numbers, the math won't lie:
1 employee, $20 per hour WITH taxes and benefits. (You're paying about $20 up front, you can't avoid the taxes, PTO, insurances):
That's 33 cents labor cost, one low-pay employee, per minute.
Recover 1 minute of break time. 2 minutes of lunch time. 1 more minute of second break.
Remember, they then work until the END OF DAY with the bell system, not slowing down 10 minutes ahead of time. That's additional work that they get done.
We can count on 4 minutes absolute minimum time recovered, per man, per day. 4x.34=$1.36 per day. 5 days: $6.80 per week.
52 weeks: $352 per year per employee in recovered labor time. Every year.
$352 x 10 employees: $3,520. Every year. And the shop becomes more organized.
