NUDM3P-HE Passive Customizable Button Module
Installation Sheet
Description
The Customizable Button module (NUDM3P-HE) is a
passive, wall-mounted device suitable for general
rooms.This module connects to a passive room bus coming
from the NUPBC-H Passive Bus Concentrator and features
three customizable buttons for different call levels.
Installation
Note:
Before beginning the installation, ensure all the
necessary cables are available.
The module can mount to a backbox or to a wall by using a
surface-mounting spacer (NUSP1-HE).
To mount the module on a backbox or spacer:
1. When using a backbox, loosen the screws on the
backbox so that approximately 5mm extend out from
the backbox and the heads of the screws can pass
though the key-hole slots of the adapter plate.
When using a spacer, ensure the spacer is properly
mounted to the wall and that the adapter screws are
available.
2. Place the adapter (with the arrow facing up) over the
backbox or spacer and ensure that it is level.
3. Tighten the screws.
4. Pull the cables from the backbox or spacer though the
adapter.
To mount a spacer to a wall:
1. Place the spacer against a flat wall and orient it so that
“TOP” (printed on the inside of the spacer) is pointing up
and that the spacer is level. Use a leveling device to check,
if necessary.
2. Using the spacer as a template, mark four holes for the
screws using the outer fitting holes located in the corners
of the spacer.
3. Remove the spacer and drill screw holes for the screws
that will be used, such as wood, concrete, or drywall
screws, or screws with anchors.
4. Remove the knock outs in the spacer for the cable wires.
5. Place the spacer over the holes, insert the screws, and then
tighten.
6.
Pull the cables though the knock out holes
.
