FIELD: fire safety.
SUBSTANCE: in a lock with thermal disconnection, comprising a body 2 of a nozzle, an output channel 11 and an output hole 10, a protective plate 20 is fixed with the help of a fusible disconnecting mechanism. The fusible disconnecting mechanism 5 with a ring (22) when applied is disconnected with the help of a heating element 23, which is installed in the ring (22), and the output hole 10 opens. A structural element 21, for instance, a plate spring, creates prerequisites for effect of the force F at the moment of melting of the fusible disconnecting mechanism 5, and the protective plate 20 is forcedly removed from the output hole.
EFFECT: invention provides for device actuation in case of accident without energy supply.
