ABSTRACT:
A signaling system includes a housing that has monolithically formed sides defining a cavity therebetween and an open rear face. A pair of U-shaped guide rails are fastened to the housing and extend vertically away therefrom along a longitudinal length of the system. A sign board is registered along the axis and includes edge portions intercalated within the guide rails. A shield is positional in front of the sign board. The system includes an electromagnetic mechanism for maintaining the shield at a lowered position when an external power source is on, a mechanism for adapting the shield to a raised position when an external power source is off, and a mechanism for automatically lowering the shield after the external power source is reactivated. The automatic lowering mechanism includes spacers and fasteners passing through the spacers to attach the automatic lowering mechanism to the housing while intercalating the adapting mechanism therebetween.
