Introduction
An alarm bell in the context of fire alarm systems is a type of audible notification appliance that is used to alert and notify building occupants of an emergency or fire situation.
Regardless of the exact terminology used, the key purpose of an alarm bell is to produce a loud, audible signal that can be heard throughout a building to alert occupants of a fire or other emergency situation. This allows the building's fire alarm system to effectively notify and warn people of the need to evacuate or take other appropriate actions.
