Based on the size, fire alarm and detection system for bigger buildings can be separated into four categories:
• Conventional fire alarm systems - these possess the desired quantity of manual call points and detectors connected into a fire alarm control panel in different zones.
With such systems, the fire alarm control panel is wired to a minimum of two sounder circuits which contain audible devices.
• Addressable systems - comparable to conventional ones, but the fire alarm control panel can ascertain exactly which detector or manual call point has activated the fire alarm, rather than identifying what can be a relatively vague ‘zone’.
• Analogue addressable fire alarm systems - also often referred to as intelligent systems, these usually involve detectors able to communicate with the fire alarm control panel. Each sensor has distinctive address and can provide information, such as status reports and analogue values. data, depending on the complexity of the system.
• Wireless fire alarm systems - wireless technologies are frequently now associated with analogue addressable systems, offering a more simple choice with less requirement for cabling.
