6” 110V Work Shift Timer Bell
High-output industrial bell designed for reliable shift and break signaling.
Description
This 6-inch 110V work shift timer bell is designed for industrial environments where a clear, unmistakable audible signal is required. It is commonly used with work shift timers to signal shift starts, breaks, lunches, and end-of-day departures in factories, shops, and large buildings.
The bell operates on 110VAC power and produces a strong, mechanical ringing sound that is easy to hear across open work areas. Output volume typically ranges from 96 to 102 decibels, depending on installation conditions. Higher available line voltage generally results in a louder bell.
This model is a straightforward, reliable signaling device that delivers consistent performance in demanding industrial settings and is backed by a two-year guarantee.

Installation Tips
- For best coverage, install one bell near the timer
- Place a second bell approximately 50 feet away in larger spaces
- Multiple bells improve audibility and reduce dead zones
Why Bell Volume Can Vary
| Condition |
Effect on Volume |
| Building voltage at 100–105V |
Quieter operation |
| Building voltage at 110–115V |
Louder operation |
| Soft surfaces (wood, boxes, wallboard) |
Sound absorbed, reduced volume |
| Hard surfaces (metal, concrete) |
Sound reflects, increased volume |
Warranty
This bell is backed by a two-year warranty.
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 painfully loud.
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.
