All Fire Alarm Systems essentially operate on the same principle. If a detector detects smoke or heat or someone operates a break glass unit (manual break point), then alarm sounders operate to warn others in the building that there may be a fire and to evacuate. It may also incorporate remote signaling equipment which would alert the fire brigade via a central station.
Fire Alarm Systems can be broken down into four categories, Conventional, Addressable, Analogue Addressable and Wireless systems.
