SM 3 • Setup Guide
This setup guide contains installation information about the Extron SM 3 speaker.
Installing the Speaker Mounting Plate
The SM 3 speaker comes with two types of speaker mounting plates:
0° mounting plate — The 0° plate allows the speaker to be mounted at on a vertical wall with the speaker protruding less
than four inches (ADA compliant) from the wall surface.
10° mounting plate — The 10° mounting plate allows the speaker to be installed at a 10 degree angle so that the speaker
can be pointed down from an elevated position.
The mounting plate can be installed vertically or horizontally as shown
on the right.

NOTE: Observe all applicable building codes and local ordinances when installing the speaker.
Mounting to a Wall Box
1. Route the speaker cable through the rear of the mounting plate and attach the wire ends to the quick connect contacts using
a small screwdriver (see the following gures on the next page). Be sure to observe the correct polarity.
NOTE: The positive (+) connector and the negative (-) connector are marked on the mounting plate.
2. Attach the mounting plate to the wall box, using two mounting screws (see gure below).
NOTE: The mounting screw holes in the mounting
plate allow for some degree of play and lateral
movement so that the mounting screws may
be aligned properly with the screw holes of the
wall box. Observe U.S. and European screw
locations, as shown on the right.
ATTENTION: Make sure that the wall box is
secured to the wall structure and can handle the
weight of the speaker. If there is doubt, secure
the mounting plate with additional mounting
screws. The wall stud mounting holes can be
used for this purpose.

SM 3 • Setup Guide (Continued)
ATTENTION: Use the appropriate mounting screws. The screw heads must not protrude more than .074” (1.9 mm)
above the screw holes in the mounting plate (see the gure below left). If the screw head protrudes too far above the
mounting plate surface, damage to the speaker may occur when the speaker is attached (see the gure below right).
Mounting to a Wall Stud
1. Install the speaker cables into the wall or conduit before installing the speaker mounting plate. Leave enough slack.
2. Locate the wall stud where the mounting plate will be installed and while positioning the mounting plate on the wall mark the
location of two pilot holes using the holes on either side of the mounting plate so that the stud does not interfere with the
speaker wire routing, as shown below.
NOTE: A speaker wire access hole (see the figures below) must also be cut in the wall, so mark that hole
location now with the mounting plate positioned on the wall while ensuring that the wall stud does not
interfere with the wire routing and that the mounting plate hides the access hole.
Mounting Screws
ATTENTION: Use the appropriate mounting screws (see the above ATTENTION).
3. Drill the mounting plate pilot holes and cut the speaker wire access hole, as previously marked.
4. Route the speaker cable through the rear of the mounting plate and attach the wire ends to the quick connect contacts
using a small screwdriver (see the illustrations at the top of this page). Besure to observe the correct polarity.
5. Attach the mounting plate to the wall.

NOTE: When mounting to surfaces that do not allow
wires to be routed from behind (such as on masonry
or concrete walls) and the wires are routed to the
speakers via a raceway, use the alternate access
points to run the wires to the quick connect speaker
contacts (see the figures above).

Attaching the Speaker to the Mounting Plate
ATTENTION: By default, the SM 3 speaker is shipped unlocked. When mounting the speaker
to the mounting plate, be sure that the speaker is unlocked. Failure to place the speaker in
the unlocked position will result in damage to the speaker lock mechanism should an attempt
be made to mount a locked speaker (see “Using the Security Key to Lock and Unlock
the Speaker” below).
NOTE: If a secondary attachment point is being used, see the “Attaching a Secondary
Support Cable” section on the next page for installation details before proceeding further.
Position the rear mounting slot of the speaker above the catch tab of the mounting plate, then
slide the speaker down into the mounting plate so that the speaker is secured in place (see gure
on the right). When properly seated, the speaker connections are automatically made.
Using the Security Key to Lock and Unlock the Speaker
Insert the key into the center of the speaker grill and turn the key, as needed, so that the speaker is
in the unlocked position (see the gure below). There are three small raised “dimples” on the grill
surface that surrounds the keyhole. Repeat this procedure, but set the key to the locked position to
lock the speaker.

Removing the Speaker from the Mounting Plate
To remove the speaker from the mounting plate, you must unlatch the
locking mechanism.
1. Insert the security key into the keyhole of the speaker grill (see the previous
section) and turn the key to the unlock position.
2. Remove the security key.
3. Apply pressure with your nger over the keyhole to unlatch the speaker
from the mounting plate while lifting up on the speaker (see gure on the right).
ATTENTION: To avoid damaging or scratching the grill nish, do not
use tools or sharp instruments to depress the unlocking mechanism
hidden behind the center of the grill.
