6” Shop and Factory Bell

  • 24VDC, they require only low voltage wiring
    --  which means no electrical permits, no conduit
  • Low current draw, put up to 8 on a single circuit
  • Easy to install
  • Normally powered by the Pyramid 5300 or Pyramid 7000 (or Pyramid 5024),
    --  which all have a 24VDC output
  • Connect with inexpensive double stranded 14 to 22 gauge Home Depot lamp cord

If you want to make it so these are “LOUD”, call us. 
We have developed a modification that connects with your 110VAC or 24VAC bell system.

Why does the volume vary, why is it not exact?  I am not an engineer, but I have observed this:

There are two factors that affect how loud these bells ring.

1) Voltage.  We have always thought that the power in the walls is 110.  That is rare.  Your power company does the least it can to make the system run, it is responsible to share holders first, you, the customer, second.  Your lines are old.  Old lines have more resistance.  As they bake in the sun, freeze in the winter, and the plastic on them rots, plus the suns rays (solar energy) weakens them.  So they deliver more power when they are new, then 20 years later.  Quite a bit more.
In the end, you are lucky to get 105 volts.  It's easy to test, buy a volt meter and stick it in a plug.
Plus, in your building, you may be drawing (using) more than the building was originally designed for.  This drops voltage.   So the bell is quieter.
2) What is in the building?  White noise (air-floating tables for woodwork)?  Boxes and fabrics? Sawing and other loud noise?  It all sucks up the bell and buzzers' volume.
This has been going on for years:  People keep asking "How loud are your bells?"  Unfortunately, it's like describing a dinner at a restaurant. It depends on the environment.  Is it an empty room like a gymnasium?  Does it have lots of rooms, or lots of background noise like a woodworking shop?  Is this a warehouse with lots of rows of shelving and boxes of fabric?

Bells and buzzers all seem to max out at 102db.  102db is very loud.
110db is extremely loud, check out the YouTube video below. 

In our experience, installing 2 to 3 bells or buzzers is much more effective than just one.   Put one by the timer, then run wire out the another, 50 to 100' away.  It won't be louder, it will just be more likely to be heard above all the background noise.

So, yours truly did some research recently (2016), this is interesting:
Using an Android phone decibel app, this is what we found:
**A bedroom at night in the country, windows closed:  28 - 32 db
**A bedroom at night in the city with the windows closed:  42- 46 db
**Office environment, people chattering:  62db

**American Airlines 737 inside just behind the wing during takeoff  86db
**Same jet, landing with the reverse thrusters on:  88db  That ROAR you hear..
**Same jet, cruising for 3 hours, it's 82 to 86db.  That's partially why flying is tiring.
Shop buzzer's:  102db (Edwards, the ones we sell)  Other brands "hum" at 82 to 86.
Our bells test out at 98 to 103db depending on voltage

It seems that no one offers anything louder than 103db, unless it goes on a train, ocean liner, or fog horn.  In some cases loudspeakers are used on farms; we don't have them, but our equipment will ring them.  This is 110db, a train horn on an obnoxious person's pickup truck.  In a working environment, this would clearly cause accidents.

More bells or horns does not make it louder, it just makes it more pervasive - easier to hear through the machinery, across the rooms, over the land.
