Abstract: An alarm system for indicating the specific location of an intrusion into an enclosed space, as well as a method for installing the alarm system, are disclosed. The intrusion causes illumination of an indicator light outside the enclosed space and within the outer perimeter zone of the enclosed space, thereby indicating the specific location of the intrusion. At least one interior sensor located within the enclosed space generates a specific intrusion location signal in response to movement therein. A control system responsive to the specific intrusion location signal causes the indicator light to emit light that is visible from outside the outer perimeter zone of the enclosed space. The emitted light can indicate the specific location of an intrusion by directing light towards the specific intrusion location, and/or by surrounding the specific intrusion location, and/or by activating a light display that produces readable output of the specific intrusion location.

Abstract: An alarm system for indicating the time that has elapsed since intrusion into an enclosed space, as well as 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 time elapsed since intrusion. At least one interior sensor is located within the enclosed space and configured to generate an intrusion time signal in response to movement therein. The indicator light is located within an outer perimeter zone of the enclosed space, and upon receiving an intrusion time signal, the indicator light emits light visible from outside the outer perimeter zone of the enclosed space. The light can indicate time elapsed via a property of the light itself, such as wavelength, intensity and/or focus, and/or via a light display producing readable output of time elapsed, for example.

Abstract: 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.
