An addressable fire system works the same as a conventional fire alarm system but there is a difference that each detector of an addressable fire alarm system is provided with a specific Address. Specific Address is given to each detector by the means of dip-switch. In this way, the control panel matches the installed address and easily identifies that which call point or detector has triggered the alarm. The detection circuit is wired as a loop and with each loop up to 99 devices can be connected. Commonly, the loop isolation module is used to fit the loops. In this way, the loop is divided into sections so that in the case of a short circuit only a limited area could be damaged. In case of a short circuit or signal fault, the remaining parts will keep their working efficiently without any disturbance.
In conventional fire alarm systems and addressable fire alarm systems, the signals are not considered ‘intelligent’, because they can give only output signals
