Abstract
Alarm and security system in elevators, which offers the user an alarm with high-powered acoustic signal and an automatic emergency lighting in the cabin, in case of producing a failure in the supply of electric fluid. It consists of an electronic circuit that includes a power supply of alternate current to current continuous in low voltage (1), to which it is connected, among others, an electrical network tension detection block (2) and an electrical battery (3) arranged in tampon circuit; of an oscillator block (4) responsible for degenerating a signal of two audible tones, such signal being applied on an amplifier block (5) which is connected with a sound transducer device (6); and an emergency button (7) associated with a signal pilot.
