Patent
CA 2631865
A sign device comprises a unitary body which is fully enclosed across a top and sides of a hollow interior so as to be weatherproof. A display supported within the hollow interior is arranged to display alpha-numeric information through a translucent display portion on the front wall of the unitary body in an active state and is arranged to be not externally visible through the display portion in an inactive state. The exterior surface is textured and arranged to resemble a natural rock to further disguise the inactive display. An indicator indicates on the rear wall which one of various modes is being displayed on the front wall by the active display. The display can display an alarm condition, for example a building alarm responsive to a fire or an unauthorized entry into a building or a personal remote alarm activated by a building occupant requiring assistance.
