Introduction This section gives an overview of the Extron SM 26 SpeedMount Surface Mount Speaker. Topics include: • About this Guide • About the SM 26 Surface Mount Speaker • Features • Application Diagram About this Guide This guide describes the Extron SM 26 surface mount speaker and discusses how to install, configure, and operate it. In this guide, the terms “SM 26” and “speaker” refer to the SM 26 surface mount speaker.
• Color options — Available in black or white finishes. • Automatic speaker connection — Recessed gold-plated contact pins integrated into each speaker automatically make an electrical connection when the speaker is mounted to the wall mounting plate. • Hidden release mechanism — The speaker automatically locks on to the wall mounting plate to prevent tampering, but a hidden release mechanism allows the speaker to be quickly unlocked without the use of tools.
Installation NOTE: Unless otherwise stated, mounting hardware is not included. This section describes the installation and setup of the SM 26 surface mount speaker.
The mounting plate can be installed vertically or horizontally, as shown below. Catch Tab Horizontal Mounting Vertical Mounting Figure 3. Positioning the Mounting Plate NOTE: Observe all applicable building codes and local ordinances when installing the speaker.
Mounting to a Wall Stud NOTE: Mounting hardware not provided. 1. Locate the wall stud where the mounting plate will be installed. 2. If using the 10° mounting adapter, position the adapter to the wall stud according to how the speaker will be angled and mark the positions of the pilot holes. See the figure below for mounting hole locations. Mounting Holes Figure 4. Mounting the Adapter If not using the adapter, position the mounting plate against the wall.
5. The SM 26 can be mounted with or without the 10° mounting adapter. In either case the wiring of the quick connect contacts remains the same, but the wire routing will vary. Routing the wires without the 10° mounting adapter Route the speaker cable through the rear of the 0° mounting plate and attach the wire ends to the quick connect contacts using a small screwdriver, as shown below. Be sure to observe the correct polarity.
Routing the wires with the 10° mounting adapter Route the speaker cable through the 10° mounting adapter and the 0° mounting plate, and attach the adapter to the 0° mounting plate using the four included screws and washers, as shown below. Then attach the wire ends to the quick connect contacts using a small screwdriver, as shown below. 10° Mounting Adapter Quick Connect Contacts 0° MountingPlate (4) 4-40 x 3/16" Screws Routing Wires Through the Adapter and Plate Figure 8.
6. Attach the mounting plate to the wall, as shown below. ATTENTION: Use the appropriate mounting screws. The screw heads must not protrude more than 0.27 inch (7 mm) above the screw holes in the mounting plate (see the figure below). If the screw head protrudes too far above the mounting plate surface, damage to the speaker may occur when the speaker is attached. 0.27” (7 mm) Good Bad 0.47” (12 mm) Figure 10.

Yoke Mounting the SM 26 The SM 26 can be mounted using the optional yoke mount kit. Refer to the Yoke Mount Kit Setup Guide for installation details. Attaching a Secondary Support Cable If a secondary support cable is being attached, attach the cable to the eye bolt, as shown below. The cable end should be properly swaged. Anchor this end to a suitable secure point. Secondary Attachment Cable Attach cable here and secure. Figure 12.
Attaching the Speaker to the Mounting Plate ATTENTION: By default, the SM 26 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” on page 12).
Setting the Tap Selector Switch (SM 26T Model Only) For the SM 26T model, insert a small screwdriver through the upper left portion of the front grille, as shown below, to adjust the tap selector switch to the desired setting. Tap Indicator for 70 volt 8Ω 70 100 8Ω Tap Indicator for 100 volt Figure 14.
Using the Security Key to Lock and Unlock the Speaker Insert the key into the center of the speaker grille and turn the key, as needed, so that the speaker is in the unlocked position (see the figure below). There are three small raised “dimples” (see the bottom figure below) on the grille 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 grille (see the previous section) and turn the key to the unlock position. 2. Remove the security key. 3. Apply pressure to the grille with your finger over the “dimpled” keyhole to unlatch the speaker from the mounting plate while lifting up on the speaker (see figure below). Press to Release Figure 17.
