Abstract
Improved alarm device, essentially characterized by the fact that it comprises a power source and an alarm device linked to each other through a panel of pushbuttons that connect a current source with an alarm device, through the lock and drivers they complement the circuit kept closed by means of pushbuttons connected in the idle state, the panel also comprising other pushbuttons that are open and that directly connect the alarm when pressed and by presenting the lock with a point of detachment from the respective driver. Until the moment in which the lock is manipulated, all this to establish two independent alarm conductors, one through the lock and another through the disconnected pushbuttons in rest state, which are mixed with the buttons of the general network establishing a pulse combination, in a secret way.
