What does a smoke alarm system include and how much does it cost?
As you said, it should be a hotel. Basic configuration: detector (smoke feeling, temperature feeling, etc.), manual alarm button, sound light alarm, controller.
If there are other linkage, you need a module; fire hydrant needs fire hydrant button; there is a fire phone, a broadcast system, it will be configured.
If it is a project, the alarm controller (host) can share one, and the field device is set according to the room.
