Factory bell systems, also known as break buzzer systems or break time alarms, are crucial for coordinating the day-to-day activities in a factory. They provide structure to the working day by signaling shift changes, breaks, and emergencies, ensuring the smooth running of operations. The best factory bell system addresses the biggest problems faced by factory managers today.

Noise Levels

Factories and warehouses are typically noisy environments with machinery, equipment, and ongoing operations creating constant background noise. Ensuring that break and lunch bells are audible to all employees amidst the noise can be difficult. Managers need to choose bell systems that are sufficiently loud and strategically place speakers to overcome the ambient noise and reach all areas of the warehouse effectively.

Carina:PA speakers deliver high-quality sound that cuts through the noise, ensuring that announcements and instructions are clearly heard by all employees. Strategic placement of these speakers throughout the warehouse can ensure that all announcements and instructions are heard loud and clear.

Visual Alerts: More than Just Audio

A bell system that only relies on audio signals may not suffice in large and diverse warehouse environments.  While bells serve as an audible signal, additional methods of notification may be necessary, such as digital displays, especially if the warehouse is spread out over a large area.

Integrated Systems: The Need for Communications and Controls Systems for Buildings

Integration will allow for greater building control and communication of signals throughout the facility. Consider whether the bell system needs to integrate with other systems in the factory such as phone systems, PA systems, or computer networks. The best bell systems will be fully integrated into PA, Intercom, and signage functionality. Carina: Building includes Carina:PA, Carina:Intercom, Carina:Signage, and Carina:IoT, an all-in-one integrated system for building control and communications.

Customization and Flexibility

Every warehouse has unique operational requirements, especially when it comes to break and lunch schedules. Some warehouses may follow specific break policies such as staggered breaks or flexible break times, requiring a bell system that offers customization and flexibility. The best bell system should be flexible, easily programmable, and able to adapt to the changing needs of the factory schedule.

A user-friendly interface is crucial for efficient operation. Learn how to set up and adjust the bell schedule in under a minute by watching this tutorial video.
