Wiring the Speaker Mounting Plate NOTE: Mounting hardware is not provided. 1. Route the two speaker wires through the rear of the mounting plate and attach the wire ends to the quick connect contacts using a small screwdriver (see the illustration below). Be sure to observe the correct polarity. NOTE: The positive (+) connector and the negative (-) connector are marked on the mounting plate. ATTENTION: Use the appropriate mounting screws. The screw heads must not protrude more than .074” (1.
2. Attach the mounting plate to the wall, using two mounting screws (see the illustrations 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. 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.
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 below).
Attaching the Speaker to the Mounting Plate Step 1: Attaching the Speaker NOTE: If a secondary attachment point is being used, see the “Attaching a Secondary Support Cable” section on page 12 for installation details before proceeding further. 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.
Step 2: Using the Security Key to Lock and Unlock the Speaker The SM 3 speaker uses an included security key to lock and unlock the speaker to its mounting plate (see the illustration below). The key has two positions: lock and unlock. The active position of the key is nearest the top of 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 figure below).
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 “Step 2: Using the Security Key to Lock and Unlock the Speaker” on page 10) and turn the key to the unlock position. 2. Remove the security key. 3. Apply pressure with your finger over the keyhole to unlatch the speaker from the mounting plate while lifting up on the speaker (see the illustration below).
Attaching a Secondary Support Cable If a secondary support cable is being attached, use the included screw to attach a suitable cable to the screw hole, as shown below. Anchor this end to a suitable secure point. Insert screw here. Attach cable here and secure.
