Abstract
An emergency locator signal light system, suitable for installation at a residence or business, which in a monitor mode is responsive to the dialing of a predetermined emergency telephone number, such as "911", to enter a command mode. In the command mode, the system is responsive to predetermined tone dialing signal sequences, which are herein termed "Star Codes", to activate an included signal light device. Exemplary "Star Codes" are "*1" for a medical emergency, whereupon red and white lights alternately flash; "*2" for a fire emergency, whereupon a white light flashes; and "*3" for a police emergency, whereupon blue and white lights alternately flash. The "Star Codes" can be dialed either locally from any telephone set or other dialing device at the residence or business from which the "911" emergency call is placed, or by an emergency telecommunicator who makes a decision to activate the flashing lamps in view of the nature of a particular emergency following a verbal description by an emergency caller.
