Abstract
Alarm device for automobiles, essentially characterized in that it is constituted by a diode inserted between the switches of the vehicle doors and a condenser that on the one hand is connected to the positive of the installation through an activating switch of the system, while for the on the other hand, it connects with a conductor that joins the diode with a resistor, which is connected to the base of a transistor as a function of the gate, the collector of said transistor being directly connected to ground, while the emitter is connected to the pole of the transistor. A capacitor and that of a coil, which are connected in series with a resistor, said coil being included in a relay provided with three contacts, one central and two ends of which one connects to the free terminal of the resistor, while the another connects with the capacitor and the activating switch of the system, having been provided between the central contact and the connected contact on the switch a connection through a capacitor while said central contact through an extension connects with the lights of the vehicle and with the coil of a second relay, also three contacts, whose coil through the free terminal connects with the output of the transistor ; which in turn connects to ground, with the particularity that the central contact of the second relay interconnects in parallel through a capacitor being the extreme output touch while the central contact is input and directly connects to ground if the horn of the vehicle switches to negative while connecting to positive if said horn switches to positive.
