Speech Module Installation Sheet
Model NUSPM-HE
Description
The NUSPM-HE Speech module handles voice
communications with other speech-capable modules. The
module can also be used as a dual tone buzzer in
HTM-compliant installations.
Module Connectors
The module includes two RJ-45 jacks for room bus
connections and DIP switches for room bus addressing.
Figure 1 shows the jacks and DIP switches on the back of
the module.

(2) 3x DIP switches for bus addressing
(3) 1x DIP switch for microphone sensitivity
Setting the Room Bus Address
The room bus address is a unique number assigned to a room
module when modules of the same type are attached to the
room bus.
If you do not use DIP switches to set the room bus address,
be sure all the DIP switches are in the OFF position on the
back of the module.
To set the DIP switches:
1. Set the DIP switches for the correct room bus address
(0...7), as shown in Figure 1, item 2.
2. Using a small screwdriver, gently slide the switch up for
“ON” or slide it down for “OFF.”
3. Set the DIP switch for the microphone sensitivity
(0dB or -6dB) using switch 1, as shown in Figure 1, item 3.
Installation
Note:
Before beginning the installation, ensure all the
necessary cables are available and are properly terminated.
RJ-45 connectors should be terminated in accordance with
the T568B or EIA 568B connection standard.
The module can mount to a backbox, or to a wall using a
surface-mounting spacer (NUSP1-HE).
To mount the module on a backbox or spacer:
1. When using a backbox, use the mounting screws that
came with the module.
-or-
When using a spacer, ensure it is properly mounted to the
wall and that the adapter screws are available. See
"Mounting a Spacer".
2. Place the adapter (with the arrow facing up) over the
backbox and ensure that it is level.
