Abstract
Abstract Lighted house numbers at night aid in the locating of an address in a non-emergency mode and becomes an alarm device including a control unit connected to a telephone within a dwelling to detect dialling of a 911 signal. A housing is mounted exteriorly of the dwelling and includes audible and visual alarms operatively connected for activation upon detection of a 911 signal by the control unit. The remote alarm unit includes indicia illuminated for identifying an address at night when operating in a non-emergency mode and directing rescue personnel to the dwelling after a dwelling occupant has dialled 911 and activates an emergency strobe light and audible alarm mode illuminating the general vicinity of the dwelling from a distance and ultimately pinpointing the exact location of the emergency 911 caller. The visual and audible alarms in the remote unit are connected through a rectifier and transformer to an AC power source within the dwelling. The remote alarm unit includes a back up battery power supply which is automatically connected upon AC power failure.
