DEVICE FOR FIRE ALARM AND RECORDING FIRE-ALARM SIGNALS

摘要

The proposed device for fire alarm and recording fire-alarm signals contains a 8-bit analog-to-digital converter, a recording unit, and a majority element that generates an output signal if two of three or three of four input signals are present. The proposed device provides a possibility to store data on the process of fire as well as the data on the time of the start and the end of the fire fighting.
