Abstract
The electronic unit enables one to gather at a central point data from detection and after analysis of the data, to generate a control pulse which triggers an alarm. The unit uses printed circuit cards and possesses cards for received data analysis, a circuit fuse card, and a card for a modulated electronic siren with integrated timing. The unit has a two position "day and night" locking system. It also has a card which supports a trigger button for switching out of circuit certain analysis cards. The unit also includes a distribution and supply system. The printed circuit cards have circuitry on them which may be normally open or normally closed either of these two circuit types can be plugged into contacts carried on a master card.
