What are the original components of the fire alarm device?

There are: alarm host, I/O module, temperature detector, smoke detector, temperature cable, manual alarm button, alarm bell, audible and visual alarm, etc.

According to different models, the host computer includes: CPU processor, circuit board, power supply, chassis, fire telephone interface, fire pump start-stop interface, etc.

Module types are divided into: input module (monitoring module) and output module (control module)

Input module, also called monitoring module, refers to the signal from external equipment entering the host for monitoring through the input module, such as the input module for monitoring water flow indicator and signal valve.

Output module, also called control module, refers to the module that controls external devices. For example, the solenoid valve is connected to the output module, and when the output module acts, a voltage is applied to the solenoid valve to make it act.

Both the input module and the output module are linkage modules. Linkage means that after the linkage host detects the alarm of a certain area or equipment through the input module, it makes the output module act through logical judgment, thus completing a set of linkage equipment.
