ABSTRACT:
The annunciator is formed of a plurality of square cross-section modules. Each module includes a plastic housing, a mother board mounted on one end of said housing, one or more point cards slidably mounted in the housing and a light card mounted in the housing. The light card carries a light reflector which is covered by a bezel having removable lenses. The light reflector is adapted to be modified to accommodate one, two, three or four signal lights. The point or light cards are plugged into the mother card. The mother card also carries a power supply mounted on a card. A terminal board is mounted on the power supply card. The rear portion of an assembly of modules is enclosed by a shroud formed of a plurality of foraminous metal plates. The multiple modules are joined together by mating pins and sockets with an assembly being tied together by a frame around the front end of the assembly.
