Pyramid 7000 scheduled workshift timer
Includes custom-made 110v-10amp protected power supply

It will be black, and slightly different inside when it is delivered to you

Master clock and bell system overview:

Single Bell Circuit, run as many bells or buzzers as needed
---  Also works with Tone Generators and PA Systems
Set up to 72 events, each event (signal) can run on multiple days
--- It will easily accomodate a 3 shift operation

No need to reset, it keeps the time when the power is off
--- and restores to the correct time when it comes back on
Automatically adjusts for daylight savings - you can turn this off.

This is an old picture, now they are black.  We've been sellling (and installing) these machines since 1997.

Pyramid 7000 scheduled workshift 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.
