Addressable systems consist of one continuous loop cable in and out of the control panel onto which are connected a number of devices including, sensors (Smoke & Heat Detectors), sounders and interfaces etc.
Each device is given a unique address, descriptive text and allocated to a zone. The control panel is then capable of providing the exact description of the device that has activated along with its location. In addition addressable systems have the ability to assess if any smoke sensors are due for replacement due to dust contamination etc.
