摘要： A glazing shattering device (10), wherein the possible operation reversibility is guaranteed, allowing to repeat a glazing shattering impact or to program several impacts in a selected number of devices connected to the safety system, comprises: a supporting frame (6) having a casing with open side, apt to be positioned facing towards a glazing (1) to be shattered; at least a hammer (2) provided with a hammer head (11) comprising at least a ferrule (12) to shatter said glazing (1), which is hinged on said supporting frame, thereby it is movable between a respective rest position, in which said at least a ferrule (12) is spaced apart from the glazing (1), and a break position, in which said at least a ferrule (12) interferes with said glazing (1), the hammer (2) comprising a preloaded elastic element (14) which keeps it in said rest position when it is not stressed; and a linear actuator (3), inserted in said casing, having a piston head (17) snap movable between a respective retracted position, wherein it does not interfere with said at least a hammer (2), and an interference position, wherein said piston head (17) pushes said at least a hammer (2) through said open side in said break position, wherein a mechanism for returning the piston head (17) in said respective rest position is provided.
