Network Buzzers In A Box – Network Work Shift Timer with Dual Buzzers

Description

Network Buzzers In A Box is a network-based work shift timer designed to automate shift changes, breaks, and scheduled alerts using two high-output buzzers. The system connects directly to an Ethernet network and maintains accurate time through network synchronization, allowing scheduled signals to occur consistently without manual adjustment. Programming is performed through a web-based interface, and schedules are stored internally so the system continues operating independently after setup.

This configuration includes a network work shift timer with external relay output, two 110VAC buzzers, a wall-mounted junction box, and installation hardware. The controller activates both buzzers at scheduled times, providing audible coverage across larger work areas. The relay-based output allows connection to standard signaling devices while keeping timing controlled by a single network-synchronized source. The system is commonly used when replacing mechanical timers or when schedules must be adjusted without accessing the physical controller.

Network-based buzzer systems are typically installed in warehouses, manufacturing facilities, schools, and multi-department environments where consistent timing is required across multiple areas. Because scheduling is managed through the network, changes can be made quickly when shift times change. The system also serves as a starting point for larger network signaling installations where additional buzzers or signaling devices may be added later.

Compatibility and Usage

  • Ethernet-connected work shift timer with network time synchronization
  • Includes two 110VAC high-output buzzers
  • External relay output for bell or buzzer control
  • Schedules stored internally for stand-alone operation
  • Used for shift changes, breaks, and scheduled alerts
  • Suitable for upgrading mechanical or standalone timers

FAQ

Does the system require a dedicated computer?
No. A computer is only needed for setup. The controller runs schedules internally.

Can additional buzzers be added later?
Yes. Additional signaling devices can be connected using appropriate relay expansion.

Why use a network-based timer?
Network synchronization prevents time drift and allows schedules to be updated without accessing the unit directly.

July 5, 2018 more to know: 
A Fire Station Siren is 106 decibals. Our bells and buzzers are typically 98 to 102.

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 so 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 conversations and running equipment like compressors, lifts, packing tape, all that.

 

All this is included, plus, the most recent update now includes setting the duration of the ring or "event" for each time.
