Automatic alarm system (automatic) :-
Automatic alarm systems are used in places and halls where the possibility of fires is high, and large losses may result in a short period of time. These systems work by being affected by fire phenomena, some of which are affected by flames or temperature, and automatic alarms are distinguished from manual ones in that they do not depend on humans to operate them, as well as Shortening the time period between the moment of the fire and the moment of its discovery, and it is divided into the following types: The traditional systems: These are systems where each group of detectors is connected to a single electrical circuit to monitor an alarm area in a building so that any detector or device in the group gives a signal to the main alarm panel that there is a fire in the alarm area as a whole without specifying the number or address of the detector.
2- Titled Systems: In this case, each detector has a specific number and a specific address that appears on the alarm panel, and one of the advantages of this system is that each detector can be controlled separately, and it can be controlled through the program and the rest of the circuit is operated until Salah
