An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is either classified as automatic, manually activated, or both. Automatic fire alarm systems can be used to notify people to evacuate in the event of a fire or other emergency, to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.

Fire Alarms:

Analogue / Addressable

Analogue: simpler and cheaper and are fine for the smaller properties. In the event of activation, you can tell from the panel which zone the activation has occurred in.

Addressable: slightly more expensive but a lot more sophisticated. In the event of an evacuation you can tell from the panel exactly which unit was activated.
