ABSTRACT:
A security device providing alarm and chime units is an inexpensive and unobtrusive system which the typical homeowner can easily install and operate. The device includes a housing having a front plate which replaces the standard residential wall outlet plate. A motion detecting sensor, a chime unit, an alarm unit capable of at least 110 decibels, and a converter to convert the alternating current to direct current are also included in the housing. A switch is provided on the housing for setting the device from OFF to ALARM or CHIME, as desired. The present invention mounts at standard electrical wall outlets and uses the available alternating current (AC) to power the device, thus eliminating the worry of a possibly discharged power source.
