Fire Alarm System

A fire alarm system is a network of devices designed to detect and alert occupants and emergency services to the presence of fire, smoke, carbon monoxide, or other fire-related emergencies. These systems are crucial in commercial, public, and industrial buildings, providing early warning to help ensure safe evacuation and minimize damage.

Main Components

• Sensors/Detectors: Detect smoke, heat, or carbon monoxide.
• Manual Call Points/Pull Stations: Allow occupants to manually trigger the alarm
• Fire Alarm Control Panel (FACP): The central hub that processes inputs from all detectors and triggers appropriate actions (e.g., activating alarms, sending signals to emergency services).
• Alarm Notification Appliances: Devices like sirens, bells, horns, strobe lights, and loudspeakers to warn building occupants.
• Power Supplies: Both primary (main electricity) and secondary (battery backup) to ensure continuous operation.

How It Works

• When a detector senses fire or smoke, or someone activates a manual call point, the control panel processes the signal and triggers alarms.
• Notification appliances sound and flash to alert people to evacuate.
• Some systems automatically notify emergency services or control safety systems, such as shutting down elevators or activating smoke control measures.
