Choosing between Electrical Boxes or P-Rings
The mounting depth of the IntelliPad Ci Keypad Module is 2-1/2”. When installed, the unit
extends 2” behind the sheetrock wall (assuming 1/2” sheetrock). Depending on how many
Keypad Modules you are installing in a room, you can choose from a single-gang to a four-gang
standard light switch plaster ring (p-ring) or a standard 36 cubic in. (or larger) electrical box.
Suitable p-rings and electrical boxes are available from your Niles dealer or local electrical sup-
ply company. Using the p-ring is best, because it gives you unobstructed access to the full depth
of the wall. In some instances, the use of a p-ring may be inappropriate, such as in a retro-fit
(existing) installation, or when building codes require that wall devices be enclosed in electrical
boxes. Contact your local building code and inspection department if unsure.
