1.5 Outside Enclosure Overview
The enclosure for the Universal Monitor’s controller board comes in two sizes:
• The large enclosure is designed to accommodate the Transformer Module and future compo-
nents, in addition to the controller board.
• The small enclosure is built to hold the controller board only.
Both enclosures are 2-3/4" deep.
Both enclosures have a built-in liquid crystal display (LCD) and a key lock, as shown in the example
below. The enclosures are made of metal to accommodate secure conduit fittings and protect compo-
nents against environmental debris.

The enclosure must be secured to a wall, either flush-mounted or recessed in the wall, as described in
2.0 - Installation - Main Board. Knockouts and access slots on the top and bottom allow easy con-
nection of wires and cables (see 4.0 - Wiring and Connections - Main Board) with either mounting
type.
