ALARM SYSTEM HAVING AN INDICATOR LIGHT THAT IS EXTERNAL TO AN ENCLOSED SPACE FOR INDICATING AN INTRUSION INTO THE ENCLOSED SPACE AND A METHOD FOR INSTALLING THE ALARM SYSTEM

摘要

An alarm system having an indicator light that is external to an enclosed space for indicating intrusion into the enclosed space, and a method for installing the alarm system, are disclosed. The alarm system detects an intrusion into the enclosed space, the intrusion thereby causing an indicator light outside the enclosed space to illuminate, thereby indicating that intrusion has occurred. The enclosed space can be an entire building, or a particular section or room of a building. At least one interior sensor is located within the enclosed space, and is configured to generate an intrusion signal in response to movement therein, while the indicator light is located outside the enclosed space, and within an outer perimeter zone of the enclosed space. Upon receiving the intrusion signal, the indicator light emits light that is visible from outside the outer perimeter zone of the enclosed space.
