A fire alarm detects smoke or fire, emitting a loud warning signal to alert occupants to danger. Crucial for early detection and evacuation, saving lives and preventing property damage.

Fire alarm panels come in various types, such as conventional and addressable. Conventional panels divide a building into zones, whereas addressable panels assign unique addresses to each device for precise identification. Intelligent panels offer advanced features like self-diagnosis and remote monitoring. The type chosen depends on the building's size and complexity.

Fire alarm panel parts include control circuits, power supply, CPU, display, keypad, communication ports, and slots for expansion modules and detectors.
