SL.PMT INSTALLATION MANUAL v1.0

POLE MOUNT SYSTEM WITH TILT CAPABILITY

The Pole Mount System SL.PMT is an easy to install and flexible suspension system designed
to allow One Systems ONE.SL loudspeaker systems to be mounted to pole structures and it
provides tilt aiming. The only models approved for use with the SL.PMT are the ONE.SL12 and
ONE.SL15 speakers. !

NO OTHER LOUDSPEAKERS SHOULD BE SUBSTITUTED!

The following actions MUST be performed PRIOR to beginning the installation of the SL.PMT:!

" 1. This installation guide must be read and completely understood!

" 2. The instruction manual “Rigging and Suspension of One Systems Products” must be
read and understood.(This instruction manual is available at www.onesystems.com. !

" 3. The manufacturer of the mounting pole MUST be consulted to verify the applicability

of the SL.PMT and ONE SYSTEMS ONE.SL loudspeaker model to the specific pole being used.
The pole must be capable of supporting the weight of the SL.PMT, the loudspeaker system and
all associated rigging and ALSO meet all required safety factors specified by local and national
codes and safe rigging practices. !

The weight of the SL.PMT is 16.1 kg (35.5 lb). The combined weight of the SL.PMT bracket and
a ONE.SL12 speaker is 42.1 kg (92.8 lb); the combined weight of the SL.PMT bracket and a
ONE.SL15 speaker is 51.1 kg (112.7 lb).!

" 4. The SL.PMT and attached speaker should be installed only by one experienced in the
overhead suspension of items and familiar with the applicable local and national codes
governing installation of these products and also governing the attachment of these products to
the specific pole structure. !

" 5. The installer should be experienced with the use of stainless steel banding systems
and banding system tools. !

" 6. The SL.PMT is constructed from structural steel and is coated with a dual-layer, zinc­rich powder coating. !

NOTE: Caution should be exercised when connecting One Systems speakers, suspension
hardware and pole structures (in regard to dissimilar metals). Compatible metals and
appropriate anode to cathode area ratios must be maintained. A structural engineer with
galvanic corrosion experience should be consulted prior to installation.

CAUTION: All structures outdoors are subjected to wind forces. These forces must be
considered when suspending any product outdoors. It is necessary to know the “Effective

Projected Area” (EPA) of the loudspeaker and SL.PMT. (See Appendix 1 in this document).

This data must be supplied to the pole manufacturer in order to determine safe operating
conditions for the loudspeaker and SL.PMT when mounted to a specific pole. See Appendix 1 in
this installation guide for effective projected areas for each system designed for use with the
SL.PMT. Periodic inspections of the bracket, loudspeaker enclosures and installation are highly
recommended!!

IMPORTANT NOTE: All products in direct weather installations can be subjected to high wind
speeds. For wind speed exposure over 74 miles per hour (119.1 kilometers per hour, 64.3
knots) the loudspeaker enclosure, bracket, banding, link assembly and any secondary safety
must be inspected for signs of damage or fatigue!

The SL.PMT consists of three parts: the pole bracket, the loudspeaker bracket and the Link
assembly. The bracket is designed for pole diameters of a minimum of 10 inches (254 mm) at the
speaker’s mounting height. Pole diameters smaller than 10 inches (254 mm) at mounting

height must not be used. The pole manufacturer MUST be consulted to determine the
structural capacity of the pole. The pole must be able to support the weight of the bracket,
loudspeaker, and all associated rigging with all required safety factors!

INSTALLATION OF THE SL.PMT

Figure 1 represents the isometric and top views of the pole bracket, including the loudspeaker
bracket section. !

The loudspeaker bracket must be removed from the main bracket before mounting the pole
bracket to the pole. The loudspeaker bracket is shown separately in Figure 2 below.

Figure 3 is a representation of the Link assembly. This assembly should be used whenever the
SL.PMT is being used.

Mount the pole mount section (see Figure 4a below) of the bracket to the pole at the desired
height on the pole. The loudspeaker bracket shown in Figure 2 should be removed prior to
hanging the pole mount section. The bracket is attached to the pole using BAND-IT stainless
steel bands. DO NOT SUBSTITUTE bands of other materials or other widths! There are SIX slots

on each side of the pole bracket for bands. ALL SIX LOCATIONS MUST BE USED.

IMPORTANT: It is REQUIRED that each of the six (6) band slots be wrapped TWICE (TWO
INDEPENDENT SINGLE WRAPS PER SLOT). This should not be confused with “double
wrapping”, which is two wraps of the band through a single buckle. This means that a
total of 12 bands and 12 buckles are required for a single SL.PMT bracket. Two
independent single wraps per slot will ensure a strong and secure mounting of the
bracket to the pole. Make certain that the two buckles are separated from each other in
each slot as shown below!

The image below illustrates the double wrapping required for each of the six slots.

Figure 5 illustrates the use of two independent bands per slot and also illustrates the use of all six
slots.!

The required banding and buckle material for non-marine / non-coastal environments is:!

" " BAND-IT" # C206R9 stainless steel bands!
" " BAND-IT" # C25699 buckles!
" " BAND-IT" # C00169 tensioning tool!

The stainless steel band is Type 201SS which is 0.030 inches (0.762 mm) thick and 0.750 inches
(19 mm) wide. This banding material is only used for “inland” environments (which is what the
SL.PMT and ONE.SL speakers are designed for).!

ANY QUESTIONS REGARDING THE BANDING SYSTEM SHOULD BE REFERRED TO
BAND-IT-IDEX TECHNICAL SUPPORT

WARNING: Do NOT Substitute banding materials or banding dimensions.

Figure 5

Installation instructions from BAND-IT should be followed exactly. Operating instructions are
supplied with the tensioning tool. (ALL BAND-IT parts and tools must be purchased separately
from BAND-IT or from their distributors. These parts and tools are not supplied by and are not
available from One Systems). !

The stainless steel banding material, buckles, and tensioning tools are available from the following
locations (or through distributors recommended by these locations):!

1. The loudspeaker bracket (Figure 2) should be attached to the loudspeaker’s U-Bracket
(ONE.SL12 or ONE.SL15’s U-Bracket) only using the supplied stainless steel bolts and
washers. DO NOT SUBSTITUTE ANY PARTS.!

2. The combination of the U-Bracket and the loudspeaker bracket from the pole mount should be

attached to the speaker. !

3. The loudspeaker with its U-Bracket attached, may now be attached to the pole bracket (Main

bracket (see Figure 4A).!

USE EXTREME CAUTION! The loudspeaker is heavy and it is likely that the desired mounting
location is high off the ground. This process should never be attempted by a single person.

TWO OR MORE PEOPLE ARE REQUIRED TO MOUNT THE LOUDSPEAKER ENCLOSURE
WITH ITS U-BRACKET ATTACHED TO THE POLE BRACKET! Safety harnesses should
always be worn when working from an elevated platform.

First, insert the M10 bolt into the pivot bolt location as shown in Figure 5 below and secure, but
do not fully tighten using the supplied M10 nylon insert nut. (DO NOT DO THIS UNTIL THE NOTE
BELOW IS READ AND UNDERSTOOD!)!

NOTE: The 18 mm diameter hollow tube must be used with the pivot bolt. Insert the M10 pivot

bolt through the 18 mm diameter hollow tube in the position shown below in red. !

" " " " " !

Now the enclosure may be set at its desired down tilt angle using the second M10 bolt (“Tilt”
bolt). The SL.PMT allows the loudspeaker to be oriented from a 0 degree down tilt to a maximum
down tilt of 35 degrees adjustable in 5 degree increments. After being positioned, both M10 bolts
should be tightened using the supplied nylon insert nuts and washers.!

UNDER NO CIRCUMSTANCES SHOULD THE LOUDSPEAKER’S DOWN TILT EXCEED 35
DEGREES FROM VERTICAL!

After the loudspeaker and U-Bracket are attached to the main bracket, the Link assembly must
be installed. The Link (see Figures 3 and 5 above) consists of stainless steel quick links, a
stainless steel turnbuckle, and several links of stainless steel chain. !

THE SL.PMT SHOULD ONLY BE INSTALLED USING THE LINK!

CAUTION: DO NOT REMOVE THE PAN PIVOT BOLT AFTER INSTALLATION!

The pan angle may be adjusted by removing the tilt aiming bolt, setting the desired angle and
then re-inserting the bolt. !

After the tilt angle is set, positioning of the Link offers additional aiming angles. Positioning
the Link on the lower position will provide support for short aiming angles (0 - 15 degrees)
and positioning it on the higher position will provide support for greater downward tilt angles
(20 - 35 degrees). These Link attachment points are shown on Figure 10 below.!

When choosing the tilt angle, please remember that One Systems recommends a downward
tilt angle of at least 5 degrees to help minimize moisture intrusion into the loudspeaker’s
enclosure.

FIGURE 10

The purpose of the Link is to provide support for the SL.PMT’s tilting at the bottom of
the bracket assembly. ONLY VERY SLIGHT TENSION SHOULD BE APPLIED WITH

THE TURNBUCKLE!

Warning: if the turnbuckle assembly is turned and the loudspeaker enclosure
angle begins to change (if the down tilt angle begins to move toward 0 degrees
vertical), then the turnbuckle has been OVER-TIGHTENED. Turn the turnbuckle
until there is VERY slight tension on the Link assembly and the down tilt of the
enclosure is set by the tilt bolts on the SL.PMT.

Make sure to use the appropriate combination of Link parts to insure proper
connection between the SL.PMT and the specific One Systems speaker. The required
combination of Link parts is determined by the down tilt angle of the enclosure, but the
turnbuckle must always be used. In certain situations, only the turnbuckle will need to
be used.

APPENDIX 1

Projected Area Values

The values below should be supplied to the specific pole manufacturer for safety
calculations. These values were determined by adding the projected areas of the high
frequency horns, the woofer cones and ports to the cross sectional area of the front
of each speaker listed below. The Effective Projected Area (EPA) will vary based on
wind direction. The values shown are for wind directions directly into the front of the
enclosure and represent maximum values.!

ONE.SL12 - - - 634.3 in2 (406,450 mm2)!

ONE.SL15 - - - 894.0 in2 (576,773 mm2)!
