Speaker/Amplifier
Model HSN1006A
1. Description
1.1 The speaker/ampliÞer consists of a 6-watt
integrated circuit ampliÞer and a 2.0 ohm speaker,
enclosed in a rugged, weather -resistant housing.
The housing is designed to be mounted either
inside or outside (Please see the Window
Mounting Bracket Detail, Figure 1) of a schoolbus,
truck, emergency van, or other similar vehicle.
1.2 The speaker/ampliÞer is used in options for
Motorola XTVA, Vehicular Adapters, and other
similar products.
1.3 The speaker/ampliÞer includes a trunnion
bracket, hanger bracket, and wall mount bracket.
These brackets enable the speaker to be mounted
in a variety of different ways. Refer to Figure 1.
The trunnion bracket provides a large variety of
permanent mountings (dashboard and accessible
Þrewall areas) for the speaker, while permitting it
to be tilted or angled for best results.
The hanger bracket (already attached to the
speaker) by itself permits temporary mounting on
projections, such as automobile windows. In this
case, the speaker must be removed from its
trunnion bracket by loosening the two wing
screws.
The wall mount bracket can be used for permanent
mountings if the trunnion bracket is too large to Þt
in inaccessible areas. In this case, remove the
trunnion bracket and attach the speaker to the wall
mount bracket using the hanger bracket. Security
screws are included for optional use in place of
wing screws.
2. Installation
¥ Nut Driver, 1/4"
¥ Nut Driver, 5/16"
2.2 Trunnion Bracket Installation Procedure (Refer to
Figure 1.)
Step 1. Remove the trunnion bracket by loosening the
two wing screws.
Step 2. Remove the three paper retainers and screws
from the trunnion bracket.
Step 3. Remove the wall mount bracket from its taped
position on the hanger bracket, and retain for
future use.
Step 4. Using the trunnion bracket as a template,
mark the location of the three desired
mounting holes.
Step 5. Centerpunch and drill a 0.157" diameter hole
at each location.
Step 6. Mount the trunnion bracket using the
supplied screws.
Step 7. Remount the speaker into the trunnion
bracket and retighten the two wing screws.
2.3 Wall Mount Bracket Installation Procedure (Refer
to Figure 1.)
Step 1. Remove the wall mount bracket from its taped
position on the hanger bracket.
Step 2. Remove the trunnion bracket and trunnion
wing screws, and retain for future use.
Step 3. Remove the two paper retainers and screws
from the wall mount bracket.
2.1 These tools are required for installation:
¥ Center punch
¥ Hammer
¥ Drill, 1/4" Chuck
¥ #22 Twist Drill (0.157") for self-tapping screws
¥ #38 Twist Drill (0.101") for self-tapping screws

2.4 Dual Trunnion and Wall Mount Installation
In some installations, such as in schoolbuses,
where the speaker may be subject to excessive
strain or abuse, it may be desirable to use both the
trunnion mounting bracket and the wall mounting
bracket. In this case, follow the procedures in both
2.2 and 2.3, but use the dimensions in Figure 2 to
locate the hole centers.

General Procedure
See the Vehicle Adapter, or mobile radio installation
manual for product-speciÞc procedure.
Step 1. Adjust the radio as described in the radio
instruction manual.
Step 2. Setup the conditions required to provide a
signal to the speaker, such as an incoming
received message and set the vehicular
adapter volume level to maximum.
Step 3. Adjust the speaker/ampliÞer volume control
(on the speaker circuit board) for a convenient
listening level heard clearly throughout the
vehicle. The adjustment can also be used to
lower minimum loudness if the installation
requires it.
