Home security system - power supply
 Sobotka, Jiří ; Bradáč, Zdeněk (referee) ; Fiedler, Petr (advisor)
The main goal of this bachelor thesis was to name all the requirements connected with alarm system power supply and to suggest a concept of a source with reserve lead-acid accumulator. Furthermore there is documentation of realisation of functional specimen. In this thesis there is a concept of stabilized power supply suppliyng the EZS components. The charging circuit for the lead-acid accumulator, connectors signaling the presence of system voltage and indicating connectors for low accumulator voltage. In the concept you can also find accumulator disconnector in case of low accumulator voltage ( liquidation accumulator voltage ). There is also piezobuzzer for the alert put on by switchboard station. The power supply was designed on the printed circuit board (PCB) and together with leadacid accumulator and transformator were placed in one box to which the supply cable is drawn.
