Abstract: A personal security alarm system which activates audible and visible alarms instantly at the location of an emergency, and simultaneously notifies security personnel of the existence and location of the emergency so that response to the call for help can be immediate. When a person is threatened, the person actuates a hand-held alarm actuator-transmitter by pressing a pushbutton. The signal is received by an area relay receiver which triggers an alarm at the location where the incident is occurring. At the same time the area relay receiver relays the state of emergency to a master computer which identifies the area relay receiver activated by the hand-held alarm actuator-transmitter. The master computer activates an annunciator and displays on a color video screen graphically and in print the floor plan or the site layout where the incident is occurring. A portable device is provided for resetting the portable alarm activator.

Abstract: The present invention provides an improved electronic parking system which has the capability of providing a relatively inexpensive personal security system to better protect patrons while in the parking garage. The invention provides increased protection through the use of a portable and convenient transmitter carried by a patron which activates a receiver-relay to summon help and activates horns and sirens to frighten away an attacker. The response of the system is immediate and does not depend on visual or auditory interpretation.
