This ISP75Q Intelligent Strobe Power Supply (hereafter
collectively refered to as “ISP”) can be installed in many different
types of vehicles. The guidelines for the installation of this product
are written so that no matter what vehicle is being used, the
installation and operation of the ISP will be simple and straight
forward.
Section 1: Selecting a mounting location
A good choice for a mounting area would be a trunk or similar
compartment. However, due to the wide variety of vehicles onto
which the ISP can be installed, this is not always possible. The
following guidelines will help the installer select an acceptable
alternative:
• The ISP should be mounted on a metal surface to aid
heat dissipation. Be sure that this surface is not one that
either generates or is exposed to excessive heat during
normal operation of the vehicle.
• Do not select a location where the ISP will be exposed to
potential damage from any unsecured or loose
equipment in the vehicle.
• Be sure the area selected will not allow the ISP to be
exposed to water.
• When routing wires, it is important to choose a path that
will keep them away from excessive heat and from any
vehicle equipment that could compromise their integrity
(ex. trunk lids, door jams, etc.).
• Be sure your mounting location does not block the
cooling fan in the rear of the unit. (Fig. 1)
• When the best mounting location has been determined,
securely fasten the ISP to its mounting surface using the
supplied hardware.
IMPORTANT! All customer supplied wires that connect to the
positive terminal of the battery must be sized to supply at
least 125% of the maximum operating current and FUSED at
the battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!
WARNING! When extending the communication wires
(BLUE & GREY), use either the Whelen 25ft cable (P/N 46-
9641638250) or similar “twisted pair” wires.
Caution: As it will be necessary to drill holes into the
mounting surface, the installer MUST be sure that no
vehicle components or other vital parts could be
damaged by the drilling process. Check both sides of
the mounting surface before drilling begins.
Section 2: Operating Instructions:
The ISP has been designed to emulate the operations of four
different types of power supplies:
Alternating Outlets. . . . . . . . . . . . . . . . . . . . . Alt. 2X2
Simultaneous Outlets (by pairs) . . . . . . . .Simul. 2X2
Simultaneous Outlets . . . . . . . . . . . . . Simul. 2X1X1
S.C. (Serial Communication). . . . . . . . . . . . . Custom
Select the desired operational mode by configuring dip switches
1, 2 & 5, located on the front panel of the power supply. The use of
dip switches 3 & 4 is explained in the “Hi-Lo Power” section.
The following will explain how to place the ISP into each of these
respective modes, as well as outline the operational procedures
for each mode.
Emulation Modes
Mode 1: Alternating Outlets (default configuration)
Dip Switches
Dip Switch configuration for Alternating Outlet-mode:
Dip Switch 1 -OFF
Dip Switch 2 - OFF
Dip Switch 5 - OFF
Control Wires
In this configuration, applying +12VDC to the control wires (using
customer supplied switches) will have the following results:
Control Wire #1 = Outlets 1 & 2 enabled
Control Wire #2 = Outlets 3 & 4 enabled
Control Wire #3 = All Outlets enabled
Control Wire #4 = See Section 3: Hi/Lo Power)
Flash Patterns: See Section 4.
Mode 2: Simultaneous Outlet Mode
Dip Switches
Dip Switch configuration for Simultaneous Outlet-mode:
Dip Switch 1 - ON
Dip Switch 2 - OFF
Dip Switch 5 - OFF
Control Wires
In this configuration, applying +12VDC to the control wires (using
customer supplied switches) will have the following results:
Control Wire #1 = Outlets 1 & 3 enabled
Control Wire #2 = Outlets 2 & 4 enabled
Control Wire #3 = All Outlets enabled
Control Wire #4 = See Section 3: Hi/Lo Power
Flash Patterns: See Section 4.

Page 3
Mode 3: Simultaneous Mode
Dip Switches
Dip switch configuration for Simultaneous -Mode:
Dip Switch 1 - OFF
Dip Switch 2 - ON
Dip Switch 5 - OFF
Control Wires
In this configuration, applying +12VDC to the control wires (using
customer supplied switches) will have the following results:
Control Wire #1 = Outlets 1 & 3 enabled
Control Wire #2 = Outlet 2 enabled
Control Wire #3 = Outlet 4 enabled
Control Wire #4 = See Section 3: Hi/Lo Power
Flash Patterns: See Section 4.
Mode 4: S.C. (Serial Communication) Mode
NOTE: When the ISP is configured for S.C. mode, it is important
to understand that the connections and operational procedures
used are quite different from any of the other modes. In S.C.
mode, Comet Flash is the only available pattern.
Dip Switches
S.C. emulation is accomplished by placing Dip Switch 5 in the ON
position. At this point, the remaining Dip Switches (1 thru 4) are
used to configure the address of the ISP for use in a S.C. system.
The addressing properties function as follows:
To Configure Address 1: To Configure Address 2:
Dip Switch 1 - ON Dip Switch 1 - OFF
Dip Switch 2 - OFF Dip Switch 2 - ON
Dip Switch 3 - OFF Dip Switch 3 - OFF
Dip Switch 4 - OFF Dip Switch 4 - OFF
Dip Switch 5 - ON Dip Switch 5 - ON
To Configure Address 3: To Configure Address 4:
Dip Switch 1 - OFF Dip Switch 1 - OFF
Dip Switch 2 - OFF Dip Switch 2 - OFF
Dip Switch 3 - ON Dip Switch 3 - OFF
Dip Switch 4 - OFF Dip Switch 4 - ON
Dip Switch 5 - ON Dip Switch 5 - ON
Control Wires
In this configuration, control wires 1, 2, 3 & 4 are not used to
enable outlets or control Hi/Lo power activation, as with the
previous modes. Outlet control and Hi/Lo power activation is
handled by the S.C. Multi-Purpose Controller.
Section 3: Hi/Lo Power
Hi/Lo power activation and functionality can be configured in any
of 4 available modes, depending upon how Dip Switches 3 & 4
are positioned. Table 2 on Page 4 outlines each of the 4
configurations and their attributes. NOTE: In S.C. emulation
mode, Hi/Lo power activation is controlled with an S.C. Multi-
Purpose Controller.
Section 4: Flash Patterns
The ISP can generate up to 8 flash patterns by activating the 4
Pattern Control wires, either individually or in combination. NOTE:
in S.C. mode, Comet Flash is the only available pattern. Table 1
on page 4 outlines all of the available patterns and the wire
activations needed to produce them.
Section 5: Diagnostix™ (Optional)
The optional Diagnostix™ display allows the operator to confirm
proper operation of not only the 4 outlets on the ISP, but of the
strobe light and strobe cable connected to these outlets as well.
Each LED indicator on the Diagnostix™ display, provides
diagnostic information for one outlet. For example; LED #1
monitors Outlet #1, etc. The LED’s appearance indicates the
condition of it’s corresponding outlet. Refer to Table 3 on Page 4.
