Introduction
The PSE475 Series Remote Strobe Power Supply represents the latest in state-of-the-art strobe warning
technology. The latest in MOSFET technology and advanced design provide efficient operation, meaning
superior performance , reliability and long life. The use of intelligent microprocessor control allows the Model
PSE475 series to offer more light pattern options and versatility than any other remote system available. The
user may select the standard Quad flash pattern or select any of five additional auxiliary patterns. In addition,
the user can utilize all flash options with
possible patterns. When connected to remote strobe heads , the PSE475 delivers the highest available level of
emergency warning signals.

WARNING!
The use of this or any warning device does not insure that all drivers can or will observe or
react to an emergency warning signal. Never take the right-of-way for granted. It is your
responsibility to be sure you can proceed safely before entering an intersection, driving
against traffic, responding at a high rate of speed, or walking on or around traffic lanes.
The effectiveness of this warning device is highly dependent upon correct mounting and
wiring. Read and follow the manufacturer’s instructions before installing or using this
device. The vehicle operator should insure daily that all features of the device operate
correctly. In use, the vehicle operator should insure the projection of the warning signal is
not blocked by vehicle components (i.e.: open trunks or compartment doors), people,
vehicles, or other obstructions.
This equipment is intended for use by authorized personnel only. It is the user’s responsibility to understand and obey all laws regarding emergency warning devices. The user
should check all applicable city, state and federal laws and regulations.
Public Safety Equipment, Inc., assumes no liability for any loss resulting from the use of
this warning device.
Proper installation is vital to the performance of this warning device and the safe operation
of the emergency vehicle. It is important to recognize that the operator of the emergency
vehicle is under psychological and physiological stress caused by the emergency situation.
The warning device should be installed in such a manner as to: A) Not reduce the output
performance of the system, B) Place the controls within convenient reach of the operator
so that he can operate the system without losing eye contact with the roadway.
Emergency warning devices often require high electrical voltages and/or currents. Properly
protect and use caution around live electrical connections. Grounding or shorting of
electrical connections can cause high current arcing, which can cause personal injury and/
or severe vehicle damage, including fire. Do not touch the strobe light tubes, the strobe
light head assemblies or the strobe power supply while the system is in operation. Wait 5
minutes after turning off the power from system before touching any internal componentry.
PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER
USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY
OF EMERGENCY PERSONNEL AND THE PUBLIC.
Unpacking and Pre-Installation
Remove the power supply from the box and examine the unit for any transit damage. Report any
damage to the carrier immediately. Inspect the supplied user parts kit , this should contain:
A. 1 POWER INPUT WIRE HARNESS ASSEMBLY consisting of one AMP 3 pin
connector with three wires , Red wire positive ( +Vdc ) , Black wire negative ( Ground / Earth)
and Green wire ( Hi/Lo intensity ). This assembly is to be connected to customer supplied
power cable ( See Installation and Mounting section ).
B. 1 CONTROL WIRE HARNESS ASSEMBLY consisting of one AMP 4 pin connector with
four wires White, Orange , Yellow and Brown. This assembly is to be connected to
customer supplied control switching ( See Installation and Mounting section).

Installation and Mounting
MOUNTING THE MODEL PSE475 STROBE LIGHT POWER SUPPLY
To obtain maximum performance and durability the Model PSE475 strobe light power supply
should be mounted as follows:
1. Mount the unit with the strobe light outlets located in such a way that they are easily accessible.
2. Mount the unit with the four supplied #8 sheet metal screws. If possible, a metal surface should be
chosen for best heat dissipation. The mounting hole pattern dimensions are shown in Figure 1. The power supply
can be used as a template to mark the drill locations. Predrill this surface with a 9/64 drill and secure
the unit.
!
WARNING!
High voltages and/or temperatures are present inside the unit. Disconnect from power and
wait 10 minutes prior to servicing or troubleshooting. Use hand and eye protection when
changing halogen lamps or flashtubes.
FIGURE 1
!
The Model PSE475 Strobe Power Supply is NOT waterproof and should be located in an area
protected from the weather and water.
WARNING!
WIRING
STROBE LIGHT HEAD CABLE CONNECTIONS
1. Install the strobe light heads in the preferred locations and route the shielded three wire cable from the
light heads to the PSE475 power supply. Leave enough cable at the power supply location so that the cables
will not be strained when connected to the power supply outlets. Follow the lighthead user instructions for
connecting the cables to the strobe light heads.

3. With the AMP 3 pin connectors terminated properly , plug each cable into the appropriate 3 position socket
on the PSE475 strobe power supply. The outlet chosen for each cable will be determined by the Flash pattern
selected. See Flash Control Switching Options Section for further details on flash selection.
POWER-INPUT WIRE HARNESS ASSEMBLY
The Power-input wire harness is to be connected to the 3 position socket connector on the PSE475 strobe
power supply. See Figure 3, page 5.
The Power harness assembly consists of red (+Vdc) and black (Ground/Earth) wires that power the
PSE475 strobe power supply and a green wire for Hi/Lo intensity control. Figure 4
The Hi/Lo intensity feature allow the strobe lights of the system to be switched into low power for night use
by connecting the green wire either to + Vdc or Ground (Earth). If this feature is not used
remove this wire.

FLASH CONTROL HARNESS ASSEMBLY
The Flash Control wire harness is to be connected to the 4 position socket connector on the PSE475
strobe power supply (See Figure 3 on page 5). The Flash Control harness consists of an AMP 4 pin connector
with 4 wires : white, orange , yellow and brown (See Figure 5). These are activated by connecting to a source of
+Vdc (they are low current inputs).
This control harness is to be connected to a customer supplied control cable, which in turn is to be connected
to a customer supplied switch to complete the installation.
Refer to the Flash control options and Switching Control variations sections for details on Flash Control
connections.

Switching Control Variations
The Model PSE475 outlet strobe light flashing sequence variations are controlled by four factors:
1. Selecting one or more of the Flash Modes available (see Table 1).
2. Determining the switching necessary to control these modes (user supplied).
3. Choosing to connect the remote strobe light head assemblies to the alternating or simultaneous
flashing functions on the power supply outlets (see Figure 6, page 8).
4. Number of remote strobe light head assemblies used in the system.

MAINTENANCE
The PSE475 Remote Strobe Power Supply has been designed to provide trouble free service. In case of
difficulty , refer to the Troubleshooting section. Periodic inspection of power supply wiring, and strobe light
head connections for shorted or open wires will assure trouble free operation. The primary cause of short
circuits has been found to be wires passing through firewalls, roofs, etc.
Troubleshooting
NOTE: DO NOT TAMPER WITH THE POWER SUPPLY. THIS UNIT IS SOLD AS A COMPLETE MODULE,
AND IS NOT DESIGNED FOR FIELD REPAIR.
All PSE475 Remote Strobe Power Supply units are thoroughly tested before shipment. However, should you
encounter a problem during installation or during the life of the product , refer to the guide below for information on troubleshooting. In most cases problems that occur will be related either to the power / control wiring,
or to the strobe light head cables that connect them to the strobe power supply. In the event that the strobe
power supply is at fault return the unit to the factory for service. Additional information may be obtained from
the factory technical help line at 314-426-2700 ext. 2132.
