Selecting a Mounting Location . . .
The logical choice for a mounting area would be a trunk or similar compartment.
However, due to the wide variety of vehicles onto which the ISP188 can be installed,
this is not always possible. The following guidelines will help the installer select an
acceptable alternative:
A)
The unit 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.
B)
Do not select a location where the power supply will be exposed to potential
damage from any unsecured or loose equipment in the vehicle.
C)
Be sure the area selected will not allow the ISP188 to be exposed to water!
D)
When routing the wires, it is important to choose a path that will keep these
wires away from excessive heat and from any 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: 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 46-9641638-250) or similar “twisted pair”
wires!
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 different mounting location.
Operating Instructions . . .
The ISP188 has been designed to emulate the operations of four existing 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
Selecting the desired operational mode is accomplished 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 “Hil/Low Power” section. The following section
will explain how to place the ISP188 into each of these respective modes, as well as
outline the operational procedures for each mode.
Section 1: Emulation Modes . . .
Ap12VDC to the control wires indicated in each mode (using customer
supplied switches) will cause the results indicated. For a listing of the available flash
patterns refer to Section 2: Flash Patterns.
ALT. 2X2X4 Mode (Default Configuration) . . .

Dip Switch 1 - OFF
Dip Switch 3 - OFF
Dip Switch 2 - ON
Dip Switch 8 - OFF
Control Wires
Control Wire #1 = Outlets 2 & 4 Enabled
Control Wire #2 = Outlets 6 & 8 Enabled

ALT 2X2X2X2 Mode . . .
Dip Switches
The dip switch configuration for ALT 2X2X2X2 Mode:
Dip Switch 1 - ON Dip Switch 3 - OFF
Dip Switch 2 - ON Dip Switch 8 - OFF
Control Wires
Control Wire #1 = Outlets 1 & 2 Enabled
Control Wire #2 = Outlets 3 & 4 Enabled
Control Wire #3 = Outlets 5 & 6 Enabled
Control Wire #4 = Outlets 7 & 8 Enabled
NOTE:
If Hi/Lo is to be used turn on dip switch 6 and use the pattern 4 control wire.
SIM 2X2X2X2 Mode . . .
Dip Switches
The dip switch configuration for SIM 2X2X2X2 Mode:
Dip Switch 1 - OFF Dip Switch 3 - ON
Dip Switch 2 - OFF Dip Switch 8 - OFF
Control Wires
Control Wire #1 = Outlets 1 & 3 Enabled
Control Wire #2 = Outlets 2 & 4 Enabled
Control Wire #3 = Outlets 5 & 7 Enabled
Control Wire #4 = Outlets 6 & 8 Enabled
NOTE:
If Hi/Low is to be used turn on dip switch 6 and use the pattern 4 control wire.
BL188C Mode . . .
When the ISP188 is configured to emulate the BL188C, it is important to understand
that the connections and operational procedures used are quite 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
ISP188 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 outlets or control
Hi/Low power activation, as with the previous modes. Outlet control and Hi/Low
power activation is handled by the B-LINK Multi-Purpose Controller.
Section 2: Flash Patterns
The ISP188 can generate any of 16 available flash patterns simply activating the 4
Pattern Control wires, either individually or in combination. Table 1 on Page 3 outlines
all of the available patterns and the wire activations needed to produce them.
Section 3: Hi/Low Power
Hi/Low power activation and functionality can be configured in any of 4 available
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/Low power activation is controlled with the 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 ISP188, 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 LEDs appearance indicates 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.
