ABSTRACT:
A system and a method for operating an intruder deterrent system by which a smoke screen is generated in response to an intruder being detected, a smoke screen generator operatively linked to the intruder detecting. To achieve an intruder deterrent system that can operate for a longer period after interruption in the power supply, latent heat is stored in a heat storage, and smoke can be generated by transferring the latent heat from the heat storage to a liquid, which liquid is evaporated. The use of the heat storage has led to the unexpected result that the smoke generator can operate independently of power to the heating elements for a very long period.
