[0015] 2. The intelligent fire alarm device of the building, through the coordinated use of protective claw plates and elastic metal sheets, can bear the external collision impact force, and use the elastic baffle plate to limit the range of movement of the protective claw plate under impact, and then cooperate with the relative displacement and pulling effect produced by the protective claw plate and the elastic metal sheet to consume the energy of the impact force, avoiding direct action on the fire alarm and causing damage to the fire alarm.
