ABSTRACT:
An alarm system incorporates a three-position wall switch which replaces a conventional two position switch, connected in circuit with a conventional exterior light fixture. The conventional light bulb in the exterior fixture is replaced by an adapter to which is connected an alarm unit and which receives the exterior light bulb. The three-position switch operates the light bulb at one half normal intensity in its normal mode and in its alarm position illuminates the bulb at its rated intensity and at the same time activates the alarm unit. The alarm may include a strobe light and horn for providing a visual and audible alarm. The alarm unit fits within the exterior light fixture and may include an auxiliary switch to allow it to be enabled or disabled as desired, while allowing the light bulb to provide two levels of brightness.
