ABSTRACT:
The device of this invention has a deployable signalling or display structure for displaying messages on a display area of the structure to signal an event that exists within the building, including a distress event. The messages are provided by indicia placed on a display area of the structure. The signalling structure is large enough to be easily seen by persons who approach the entrance to the building, as well as persons at a safe distance from the building. The deployable signalling structure is stored within an enclosure adapted for installation to a portion of the building with a deployment opening directed to an exterior location away from the building. The signalling structure is deployed by forcing a fluid into the structure by way of a supply conduit from a deployment unit. A control valve is used to control the supply of fluid to the signalling structure from the deployment unit and to maintain the signalling structure deployed. The signalling structure is deployed when the deployment unit is activated by an alarm device which may be associated with the building alarm system. Dual deployment units can be used for very large signalling or display structures. A means for restoring the structure in the enclosure is also provided.
