This setup guide contains installation information for the Extron SF 26PT Pendant Speaker.

NOTE: Observe all

applicable building codes and local ordinances when installing the SF 26PT speaker.

NOTE: The 2 speaker

wires of the PendantConnect-2 cable are a red wire with a black stripe (black) and a solid red wire (red). Throughout the rest of this guide the speaker wires are referred to as either being black or red.

NOTE: This speaker is intended for

indoor dry environment only.

WARNING: Risk of personal injury or

property damage.

• The nal installation should be able to

continuously support the speaker weight. The nal installation should also be able to support any short term overloading. Since applications can vary considerably, it is assumed that the installer will exercise good judgment when selecting the mounting location, method, and hardware. Installation and service must be performed by authorized personnel only.

• In order to ensure that the cable lock is not

unintentionally unlocked, keep the area within 2 inches of the cable lock in all directions free

of any other objects.

AVERTISSEMENT : Risque de dommages

corporels ou matériels.

• L’installation nale doit pouvoir supporter

en permanence le poids de l’enceinte. L’installation nale doit également supporter toute surcharge temporaire. Étant donné la possibilité d’évolution considérable des applications, il est supposé que l’installateur fera preuve de discernement lors de la sélection de l’emplacement, du mode, et du matériel de montage. L’installation et la maintenance du système doivent être exclusivement effectuées par le personnel autorisé.

• An d’assurer que le verrou du câble ne

soit involontairement enclenché, libérez l’espace situé dans un intervalle de cinq centimètres autour du verrou de tout autre objet.

Installing the SF 26PT Speaker with the Default Hardware

The SF 26PT speaker assembly includes the SF 26PT speakers with removable top caps, removable grilles, and a 30-foot length of PendantConnect-2 (PCC-2) suspension cable that incorporates both the speaker wires and two steel support cables.

Installation requires attaching two steel cables to a suitable mounting point, such as a pipe or eye bolt, attaching the swaged ends of the cables to a hook for the speaker, and routing the two speaker wires to the 2-pole splicing connectors on the speaker. Follow the steps below to properly install the speaker. Locate a suitable permanent mounting location for the SF 26PT where the two support cables can be securely attached.

NOTE: The structural member of the building must

be able to support the complete speaker assembly including the speaker and cap, support cables, the speaker grille, and any optional accessories. See the

Warning at the beginning of this guide.

NOTE: To help determine the necessary length of

PCC-2 cable needed, if pre-cutting, refer to the “Reference Information” section of the user guide, otherwise follow the numbered steps below.

NOTE: The speaker comes in a bag that helps to keep

the speaker clean during installation.

Installing the Mounting Hardware

1. Locate a suitable mounting point for the SF 26PT, such

as a pipe or an eye bolt.

2. After determining the longest length of the two support

cables that will be needed to attach the speaker to the structure attachment points, cut the 30-foot PCC-2 cable so that the 2 steel cables and 2 speaker wires are all of the same length.

ATTENTION: Do not use regular wire cutters

to cut through the steel cable. Ordinary wire cutters may be damaged when attempting to cut through the steel cable. You must use a suitable cable cutter to cut the steel cable.

ATTENTION : N’utilisez pas de cisaille standard

pour couper le câble en acier. Ce type de cisaille peut être endommagé lors de la coupe du câble en acier. Vous devez utiliser une pince coupecâble adaptée à ce type de câble.

NOTE: Be sure to allow extra cable length for the

structure attachment points

3. Strip back as much of the PCC-2 outer jacket as needed.

4. If the optional ceiling bracket is being installed, see

Optional Ceiling Bracket Kit on page 4, otherwise continue

with the next step.

5. At the structure attachment point end of the support cables,

route the cut end of one cable through one end of the cable lock 1, then route the cable around or through the attachment structure 2 using as much cable as needed to allow the speaker to be positioned at the correct height. An attachment example is shown below. Do this step for both cables.

6. After ensuring that the cable is of sufcient length to

position the speaker at the proper installation height, run the free end of the cable through the open end of the cable lock 3 and secure it in place, as shown above. Do this step for both cables.

NOTE: In order to ensure that the cable lock is not

unintentionally unlocked, keep the area within 2 inches of the cable lock in all directions free of any other objects. See the Warning at the beginning of this guide.

8. Lift one lever of one 3-pole splicing connector 1 and

insert the stripped end of the red speaker wire into an empty pole of the connector 2. Press the lever down to lock the red wire in place 3.

Do the same with the second 3-pole splicing connector for the black speaker wire.

9. Connect the speaker/amplier wires to the 3-pole

splicing connectors in step 8.

a. Strip 0.43 inch (11 mm) from the ends of the black

and red amplier wires. These wires will be inserted into the two 3-pole splicing connectors.

T TIN the wires.

b. The red speaker/amplier wire connects to the

splicing connector wired to the red wire, and the black speaker/amplier wire coming from the junction box connects to the splicing connector wired to the black wire.

NOTE: Each pole of the splicing connector is

capable of accepting up to 12 AWG wire.

10. When daisy-chaining speakers, wire the 3-pole splicing

connectors for a Loop-through conguration.

Loop-through:

Red Wire (+) from Previous Speaker/Ampliﬁer

Red Wire (+) to Next Speaker

7. To connect the speaker wires to the ampliﬁer:

On the cut end of the PCC-2 cable, strip 0.43 inch (11 mm) from the ends of the protruding black and red wires. These wires will be inserted into the two 3-pole splicing connectors (included).

T TIN the wires.

NOTE: Wiring is the same for all hanging methods

where PCC-2 cable is used. If it is not used, the 2-pole splicing connectors at the speaker should be replaced with the provided 3-pole splicing connectors. Refer to Speaker Installation and

Configuration for details.

NOTE: Setting the tap switch is the same for all

installation metnods.
