Fire detection devices are individually connected to conventional fire alarm panels using wires. If a connected device detects signs of a fire (such as smoke or heat), it will send a signal to the control panel and set off the alarm. The panel will show you which 'zone' (or area) of your building the fire has been detected. For example, 'Zone 1' could be set up as the ground floor; 'Zone 2' could tbe set up as the first floor. A conventional fire alarm system comprises of Panel, Detector, Hooter and Manual call Point, During Fire stage the alarm will ring and display would be shown in Zone wise (Eg Chemistry Lab whole section) Hooter will give siren alarm in that particular zone.

An addressable fire alarm system is made up of a series of fire detectors and devices that are connected back to a central control panel. With addressable systems, each device has an address or location, enabling the exact detector that was triggered to be quickly identified. This makes addressable alarm systems ideal for large buildings, particularly commercial premises spread over a wide area. Addressable Fire Alarm is to provide more efficient detection and prevention. Each addressable detector has its own address, During fire stage The detector gives the exact address of the location (eg Laboratory Section A) is in fire and gives alarm so rescue team can immediately go and rescue. Addressable system designed both in wired and wireless System saves much of cabling work and works on independent battery so we have to make sure to change the battery once in year or depending on manufacturer direction.

Fire alarm control panels with one way or two way voice, addressable and conventional controls. The equipment is designed with ultra-sensitive smoke detection and digital voice command evacuation systems. These panels can be used in a smaller building up to extensive and more complex networks for larger, high-rise buildings or multiple buildings in a campus configuration.

This type of Fire alarm system can be used for small business purpose where there is limited space or limited no of worker working in a small place it consists of Detector with Hooter when smoke or fire occurs it begins to alarm continuously.
