Beschreibung
Zusammenfassung:	An integrated line voltage converter and microprocessor-controlled tone generator allow advanced alarm features to be implemented in standard appliances as powered by a high-voltage line power. An integrated switch may also be used to allow the addition of alarm features to standard appliances as a drop-in replacement for door switches. Un convertidor de voltaje de línea integrado y generador de tono controlado por microprocesador permiten funciones avanzadas de alarma para ser implementadas en los aparatos estándar que sean alimentados por la energía de una línea de alto voltaje. Un interruptor integrado también puede ser utilizado para permitir la adición de características de alarma en aparatos estándar como un sustituto directo de los interruptores de puerta.
