Abstract

Improvements in or relating to safety devices, characterized in that the apparatus comprises an electric oscillator that incorporates a feedback path, a switching means with said feedback path, sensing means for detecting the appearance of an undesirable state in an equipment associated with the apparatus of security, means for opening said switching means in response to the detection of an undesirable state by said sensor means, in order to thereby cause said oscillator to stop oscillating; and output means that respond to the fact that the oscillator ceases to oscillate.
