FIELD: safety.
SUBSTANCE: invention relates to signalling devices and can be used for protection of buildings and facilities for various purposes. Security alarm device comprises a housing, moving member spring-loaded relative to the housing, magnetoelectric generator, a shaft of which in a cocked position is kinematically connected to the moving member, and a drive with stored energy, interacting with the generator shaft. Kinematic connection is made in the form of a converter of rotational movement of the generator shaft into translational movement of the movable member.
EFFECT: technical result is decreased dimensions and weight of the device.
