Manual Fire Bell

• Function: The primary function of a manual fire bell is to provide an audible alert during a fire emergency. It is manually activated by an individual who identifies the presence of a fire or receives a fire alarm signal.
• Design: Manual fire bells are typically designed as a round or rectangular metal bell with a clapper inside. When the bell is struck or activated, the clapper swings back and forth, striking the sides of the bell to produce a loud ringing sound.
• Activation: Manual fire bells are activated by pulling a lever or a handle, which causes the clapper to strike the bell repeatedly. The lever or handle is usually located near exits, fire alarm panels, or other easily accessible areas.
• Audibility: Manual fire bells are designed to produce a loud and distinctive sound that can be heard throughout the building or facility. The sound is intended to alert occupants and prompt them to take immediate action in response to the fire emergency.
• Integration: Manual fire bells are often integrated into larger fire alarm systems. When the fire alarm system is activated, either manually or by automatic fire detection devices, it triggers the activation of the fire bells along with other alarm devices such as strobe lights and sirens.
