Patent ID: 8760304

Claim:
A system, comprising: a plurality of security barriers attached to a structure such that the security barriers are operable to move from a first position in which the security barrier blocks an exterior opening of the structure to a second position in which the security barrier does not block the exterior opening of the structure, wherein each of the plurality of security barriers is associated with a location within the structure and the structure includes a plurality of locations; a plurality of glass breaking mechanisms operable to clear glass from an exterior opening of the structure, wherein each of the plurality of glass breaking mechanisms is associated with one of the plurality of security barriers; a plurality of latch mechanisms operable to control movement of the security barriers from the first position to the second position; a plurality of sensors operable to generate an emergency signal indicating an emergency condition within the structure, wherein each of the plurality of sensors is associated with a location within the structure; and a control unit operable to: detect that one of the plurality of sensors is non-communicative with the control unit; determine the location within the structure of the non-communicative sensor; and generate, in response to detecting the non-communicative sensor, a release signal to be communicated to the latch mechanisms associated with the determined location of the non-communicative sensor; the control unit further operable to: access the emergency signal generated by one of the plurality of sensors; determine the location within the structure of the emergency condition based on the emergency signal; generate, in response to the emergency signal, the release signal to be communicated to the latch mechanisms of the security barriers associated with the location of the emergency condition; activate, in response to the emergency signal, the glass breaking mechanisms associated with the security barriers associated with the determined location of the emergency condition; and activate, in response to the emergency signal, ventilation devices operable to remove harmful gas from the structure.
