The electrical component that is responsible for detecting a fire is called a fire alarm detector. Detectors have three types: smoke, heat, and flame. Depending on the type of usage, they are installed on the ceiling or wall in different places such as corridors, residential houses, motorhomes, etc. In the case of danger or fire, the information will be sent to the control panel.

Fire alarm knob is one of the important components in the fire alarm system, which is called by names such as push-button or fire alarm knob. With the fire alarm knob, we can send a warning to the fire center manually by breaking the push-button glass or squeezing it and sending a warning signal to the fire alarm center by the people present at the scene who find out about the fire.

Also, the fire alarm panel must have a battery and a charger to continue working when the system is switched off.

The occurrence of a short circuit in the loop circuit in the addressable fire alarm system causes the failure of all equipment (detectors, pushbuttons, alarms, etc.) on the loop. Short circuit isolators can be used to prevent such a problem. According to the NFPA72 fire alarm standard, in the event of a short circuit, the loop should not be more than one zone out of the circuit. Therefore, in designing for each zone in each addressable loop, you must consider a short-circuit isolator.

Alarms and alarms are sound and audible warning devices that alert everyone present at the scene. Fire alarms should be heard on stairs, in warehouses, and in all protected areas. There should be at least one alarm in each zone, and it is better to use a lot number of alarms or a low-pitched alarm than to use a few loud alarms. Flasher is one of the components of a fire alarm system. The structure of the flasher is either fixed or flashing, or rotating, and is usually red. Flashers are installed in two places: 1- Stairs, corridors and stairs 2- Above the door of the rooms
