Fire alarm system

A fire alarm system is a network of interconnected devices designed to detect and alert people about the presence of fire or smoke in a building. Its primary purpose is to provide early warning to occupants, allowing them to evacuate safely and to alert emergency services.

Here are some key components and features commonly found in fire alarm systems:

1. Smoke Detectors: These devices are the most common fire detection components. They sense the presence of smoke particles in the air and trigger the alarm when a certain threshold is reached.
2. Heat Detectors: Heat detectors monitor temperature changes in the environment. They are useful in areas where smoke detectors may not be suitable, such as kitchens or garages.
3. Fire Alarm Control Panel (FACP): The FACP is the brain of the fire alarm system. It receives signals from the detection devices and activates alarms and other safety measures. It also provides visual and audible indications of the system’s status.
4. Notification Devices: These include devices like sirens, bells, horns, strobe lights, or voice evacuation systems. They are activated when a fire alarm is triggered, alerting occupants to evacuate the building.
5. Manual Call Points: These are wall-mounted devices that allow people to manually trigger the fire alarm system by breaking a glass or pressing a button in case of an emergency.
