Abstract: After determining that a gunshot has been fired, particularly indoors, the method of the invention is employed to determining the number of gunshots fired by analyzing consecutive windows of time over a certain time period. That is, after it is determined that a gun has been fired, the method is employed to identify that the gun is an automatic or rapid fire weapon by quickly counting the number of rounds shot over short periods of time. This information can be used to provide shooting details, both in connection with notifying emergency personnel and enabling the personnel to assess details of the shooting incident.

Abstract: A passive infrared motion detector discriminates between the motion of humans and pets in a premises. The motion detector includes an infrared sensor and a mirror for focusing infrared radiation from distinct fields of view. In one embodiment, a mask prevents infrared radiation from reaching the infrared sensor, and cut away regions on the surface of the mask allow selective passage of infrared radiation to the infrared sensor. In an alternative embodiment, the cylindrical mirror elements includes reflective and unreflective regions, which allow selective passage of infrared radiation to the infrared sensor. The cut away regions and the reflective regions are elongated to correspond to the shape of standing humans. As a result, the infrared radiation from animals only partially reaches the infrared sensor.

Abstract: A system and method for acoustically detecting the firing of gunshots indoors employs multiple microphones (15, 20) which are utilized individually and in combination to detect sounds inside a building or other structure and, upon sensing a loud impulsive sound which is indicative of a gunshot, processing signals from both microphones (15, 20) to determine if the sound is that of a gunshot. The system and method relies on the acoustic signature of the noise as collected, with the acoustic signature being analyzed to arrive at values which are then compared to adjustable levels that signify a gunshot.

Abstract: A strobe notification appliance and an emergency lighting appliance that output directional information are disclosed. The strobe notification appliance may generate, in addition to notification of the fire condition, directional information (e.g., such as away from the unavailable exit paths and/or toward the preferred exit paths). For example, the strobe notification appliance includes a strobe element outputting fire notification information and a directional light element outputting directional information. The emergency lighting appliance may also operate in different modes, such as a power failure mode in which the emergency lighting appliance outputs light responsive to a power failure, and an alert mode (e.g., fire alert or mass notification alert mode) in which the emergency lighting appliance outputs light to convey directional information in order to guide occupants of a building. In this way, the occupants may be notified of an alarm event and notified of available or unavailable exit paths.
