Conventional fire alarm systems involve initiating devices such as smoke detectors, heat detectors and water flow switches being connected in a loop (zone). When the system is activated, it can mean that any one or all devices are activated. This is because each device does not have unique addresses/IDs in the loop (zone).
Addressable fire alarm systems involve initiating devices such as smoke detectors, heat detectors and water flow switches having their own unique addresses. Contrasted with conventional fire alarm systems, when the alarm system is activated, it is possible to pin-point which device has been activated, thus giving the ability to address the hazard at its specific premises or location.
