Warnings to Installers
Whelen’s emergency vehicle warning devices must be properly mounted and wired in order to be effective and safe. Read and follow all of Whelen’s written
instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for
when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate the system without
taking their eyes off the roadway. Emergency warning devices can 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 vehicle
damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic interference. Therefore, after
installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other
components within the vehicle. Never power emergency warning equipment from the same circuit or share the same grounding circuit with radio
communication equipment. All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of
sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted. This
device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any. Any device mounted in the deployment
area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its
mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a
method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow
instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. 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.
Warnings to Users
Whelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and
personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other
drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely
before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning
devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible
warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility
to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations prior to the use of
any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away from the vehicle
occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be installed and
operated in accordance with the standards established by the National Fire Protection Association.
Safety First
This document provides all the necessary information to allow your Whelen product to be properly and safely installed. Before beginning the installation and/or
operation of your new product, the installation technician and operator must read this manual completely. Important information is contained herein that could
prevent serious injury or damage.

This ISP18824 Intelligent Strobe Power Supply can be installed in many
different types of vehicles. The guidelines for the installation of this prod-
uct are written so that no matter what vehicle is being used, the installation
will be simple and straight forward.
Selecting a Mounting Location:
The logical choice for a mounting area would be a trunk or similar com-
partment. However, due to the wide variety of vehicles onto which the
ISP18824 can be installed, this is not always possible. The following
guidelines will help the installer select an alternative:
A) The unit should be mounted on a metal surface to aid heat dissipa-
tion. Be sure that this surface is not one that either generates or is
exposed to excessive heat during normal operation of the vehicle.
B) Do not select a location where the power supply will be exposed to
potential damage from any unsecured or loose equipment.
C) Be sure the area selected will not be exposed to water.
D) When routing the wires, it is important to choose a path that will keep
the wires away from excessive heat or vehicle equipment that could
compromise the integrity of the wires (ex. trunk lids, door jams, etc.).
E) Be sure your mounting location does not block the cooling fan in the
rear of the unit. (See last page)
WARNING! When extending the communication wires (BLUE &
GREY), use either the Whelen 25ft cable (P/N 46-9641638-250) or
similar “twisted pair” wires.
WARNING! 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!
Caution: Permanent mounting of this product will require
drilling. It is absolutely necessary to make sure that no other vehicle
components could be damaged by this process. Check both sides of
the mounting surface before starting. If damage is likely, select a dif-
ferent mounting location.
Operating Instructions:
The ISP18824 has been designed to emulate the operations of four exist-
ing Whelen power supplies:
The UPS-188C / Alternating Pairs .................................. ALT 2X2X4
The DOT-188C / Simultaneous Pairs ........................SIMUL. 2X2X4
The DOT-188MN / Simultaneous ...............................SIMUL. 2X2X4
The BL188C............................................................................ B-LINK
Select the desired operational mode by configuring dip switches #1, 2 3 &
8, located on the front panel of the power supply. The use of Dip Switches
#4 & 5 is explained in the “Hi-Lo Power” section. The following section will
explain how to place the ISP18824 into each of these respective modes,
as well as outline the operational procedures for each mode.
Section 1: Emulation Modes:
Applying +24VDC to the control wires indicated in each mode (using cus-
tomer supplied switches) will cause the results indicated. For a listing of
the available flash patterns refer to Section 2: Flash Patterns.

When the ISP18824 is configured to emulate the BL188C, it is important
to understand that the connections and operational procedures used are
different from any of the other modes.
Dip Switches
BL188C emulation is accomplished by placing Dip Switch 8 in the ON
position. At this point, the remaining Dip Switches (1 thru 3) are used to
configure the address of the ISP18824 for use in a B-LINK 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
To Configure Address 3
Dip Switch 1 - OFF Dip Switch 2 - OFF Dip Switch 3 - ON
Control Wires
In this configuration, control wires 1, 2, 3 & 4 are not used to enable out-
lets or control Hi/Lo power activation, as with the previous modes. Outlet
control and Hi/Lo power activation is handled by the B-LINK Multi-Purpose
Controller.
Section 2: Flash Patterns
The ISP18824 can generate any of 16 available flash patterns simply acti-
vating the 4 Pattern Control wires, either individually or in combination.
Table 1 on Page 3 outlines all of the available patterns and the wire activa-
tions needed to produce them.
Section 3: Hi/Lo Power
Hi/Lo power activation and functionality can be configured in any of 4
modes, depending upon how Dip Switches 4 & 5 are positioned. Table 2
on Page 3 outlines each of the 4 configurations and their attributes.
NOTE: In BL188C emulation mode, Hi/Lo power activation is controlled
with a B-LINK Multi-Purpose Controller.
Section 4: Diagnostix™ / Optional
The optional Diagnostix™ display allows the operator to confirm proper
operation of not only the 8 outlets on the ISP18824, 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 indi-
cates the condition of it’s corresponding outlet. Refer to Table 3 on Page 3.
Section 5: Phasing
When you turn dip switch 7 on, you will cause outlets 1-4 to drift slowly in
and out of sync with outlets 5-8. Lights will work as described in each
mode. The result will be a more eye catching or random flash pattern.
IMPORTANT! It is the responsibility of the installation technician to
make sure that the installation and operation of this product will not
interfere with or compromise the operation or efficiency of any
vehicle equipment!
