OUTING
Amplifier Installation (Remote Mount)
Locate a suitable mounting location. We recommend a cool,
dry area. Before drilling holes, check for clearance to prevent
damage to the amplifier or any other components being
installed. Check both sides of the mounting surface before
drilling and be aware of any vehicle components or other vital
parts that may be damaged during drilling. It is the installer’s
responsibility to verify this information.
WARNING: DO NOT MOUNT COMPONENTS IN OR ROUTE
WIRING THROUGH AIR BAG DEPLOYMENT ZONES.
1. Slide ¼” hex head bolts into siren amplifier t-slots.
2. Place mounting brackets over bolts. Adjust forward or
rearward as needed.
3. Thread ¼” lock nuts onto bolts and tighten down.
4. Mark the anchor points where the amplifier is to be
mounted.
5. Remove the amplifier from the mounting area.
6. If necessary, pre-drill any mounting holes into the mounting
surface.
7. Secure the amplifier to the mounting surface with the
included hardware.
Control Panel Installation (Remote Mount w/ Optional
Bail Bracket PSRN5BLBK1)
Find a suitable location for the remote-mounted Control Panel.
We recommend a cool, dry area. Before drilling any holes, check for
clearance to prevent damage to the control panel or any other
components.
WARNING: DO NOT MOUNT COMPONENTS IN OR ROUTE WIRING
THROUGH AIR BAG DEPLOYMENT ZONES.
1. Install the bail bracket using the included screws and square nuts.
2. Mark the installation location anchor points where the bail bracket
is to mount to the surface.
3. Remove the control panel and bail bracket from the mounting
area.
4. If necessary, pre-drill any mounting holes into the mounting
surface.
5. Secure the bail bracket to the mounting surface with the included
hardware.
Console Mount Sirens
Console mount sirens are intended to be mounted into a
prefabricated or aftermarket console. Follow the directions for
mounting equipment into the aftermarket console. For best results
use equipment-specific brackets or faceplates.

See the image above. Connect 12 VDC power directly to the screw-
down block on the upper control board inside the siren (left side of
image). Use a 1/8” Allen/hex wrench and torque to the
recommendation shown on the table to the left. There is a provided
pass-through hole in the siren for routing this power circuit into the
siren, labeled CN1 on the back cover. When making the connection,
be sure to use either of the included wire ferrules to provide a tight
and secure connection.
NOTICE: WIRE FERRULES MUST BE USED. DO NOT TIGHTEN THE
BLOCK ON BARE WIRE.
We recommend crimping the ferrules using the manufacturer
recommended crimpers (SQ28-10 or TRAP24-10) or equivalents.
The chart on the next page shows the recommended ferrule size for
the supply circuit size as well as the recommended wire gauge for
various amperage loads. This circuit supplies power for all the solid-
state and internal relays (CN2, CN4, CN5 & CN6). The upper control
board is rated for no more than 75A total. When fusing, use a fuse
rated for 125% of the total switched current in your application
PLEASE NOTE: The wire and ferrule combination determine the
maximum amperage throughput for the connection, based on ferrule
to wire surface contact. These ratings are recommended by the
connector manufacturer.
NOTICE: TO PREVENT STRAIN ON ALL CONNECTORS AND TO
ALLOW FOR EASE OF FUTURE SERVICEABILITY, WE RECOMMEND
INSTALLERS LEAVE SUFFICIENT EXTRA LENGTH OF WIRE TO
PROVIDE A SERVICE LOOP. THIS SERVICE LOOP SHOULD BE
SECURED TO THE INSTALLATION PLATFORM OR A TIE DOWN
POINT.
