Set-Up & Installation:
1. Get to know the product:
▪Before proceeding it is important to familiarise yourself with the product by referring to
Appendices 1 & 2 of this instruction manual
2. Temporary Power Supply:
▪Where possible, use a suitable temporary power supply to assist in the set-up procedure.
Refer to Appendix 3 for connectivity
3. Speaker Output selection:
▪Determine speaker set-up requirements –refer to Appendix 6
▪Follow the instructions in Appendices 7 & 8 to check and alter the output settings
4. Installation:
▪Decide upon a suitable and secure location for the unit (see Appendix 13)
▪The location must:
➢be dry
➢be a firm and flat surface (ideally metal)
➢be away from any local sources of heat and warm air
➢not restrict the unit’s ventilation (see Appendix 13)
➢allow access to the reset button and status LED
5. Power Supply Harness:
▪Before installing the power supply harness into the vehicle, it is important to consider the
following:
➢Always use the harness supplied with the unit. Once the cable routing is determined
the wires can be cut to the required length
➢If the supplied harness is not a suitable length ,they can be replaced with cables of
equal gauge and specification
➢When routing cables through bulkheads, rubber grommets should be used to prevent
the wires from becoming damaged or cut
➢The power should always be taken from the vehicle’s battery via a waterproof fuse
mounted as close to the battery terminal as possible. Note that any cable between
the fuse and the battery will not be protected
➢DO NOT insert the fuse until the installation is complete
➢Refer to the tables in Appendix 11 for fuse ratings

M373.1.1 - 6 - October 2022
Key to Front Panel
1. MASTER INPUT: Used for controlling siren by handset/control panel or microphone. Provides a
power feed for the control panel
2. SLAVE OUTPUT 1: Acts as an extension to provide CAN or LIN bus control to other equipment
such as Lightbar controller, flasher etc. Does not provide a power feed
3. SLAVE OUTPUT 2: Acts as an extension and is normally occupied by external EuroSmart switcher
(if used). Does not provide a power feed
4. I/O CONNECTOR: For connection to vehicle horn, position lamps, interlock, data logger, radio,
and programmable inputs
5. POWER INPUT & SPEAKER OUTPUT: Provides power, ground, and speaker connections - See
Appendix 3 & 8
6. USB PROGRAMMING SOCKET: Allows the siren to be set up using the EuroSmart USB
programming software
7. 2 & 8-WAY SWITCHED OUTPUTS: If fitted, allows the user to control external equipment via the
programmable switched outputs. Each output is rated up to 10A (max. 32A total for 8-way
boards) - See Appendices 4 & 5
8. PROGRAMMABLE INPUTS: Positive or negative switched inputs, any of which can be assigned to
control any output. Also, able to sense signals related to vehicle operating conditions, i.e., parking
brake, ignition switch or position lamps - See Appendix 3
9. POWER FOR SWITCHED OUTPUTS: Requires two positive feeds rated at 16A each and one
negative return - See Appendix 5
10. COOLING AIR VENTS: The amplifier uses forced air cooling. The cooling fan draws air in from the
rear of the unit and exhausts through the front –See Appendix 13
IMPORTANT Do not block the air intake or cooling vents. The fan will switch on automatically when the
temperature of the heatsink rises above 50OC. It will then vary its speed automatically as the temperature
changes. A minimum void of 50mm around the siren must be kept clear to allow for heat dissipation and
even air flow

▪Indicates if a fault or event has been logged
▪To provide protection the unit will not output any power to the speaker when a fault is
indicated –See Appendix 9
▪When a fault is corrected the indicator will go off and normal operating mode is resumed
▪In the case of an overheat the event log will clear itself without user interaction once the
temperature falls back within normal operating parameters
2. SET-UP / RESET BUTTON
▪If a fault is detected press & hold the button for 3 seconds to clear the event log
▪If the log cannot be cleared, please refer to Appendix 9 for the event code
in order to carry out relevant investigations to diagnose and rectify the fault
▪Please note that the Reset/Setup button is also used to read and configure the
impedance and power settings

Appendix 6 |Speaker Installation
▪When two or more speakers are wired in series it is important to connect positive (+ve) of one
speaker to the negative (-ve) of the next
▪When connecting multiple speakers, they must have the same power rating and impedance
▪See below diagrams for speaker wiring configurations
Calculating Speaker Impedance
▪Z= Impedance of a single speaker
▪ZT = Total Impedance
▪N= Number of speakers
▪Where an application requires two or more speakers ensure that the correct impedance is
calculated using the below formula and selected on the amplifier. (Note: Speakers must be of
identical power and impedance)
➢For two or more speakers connected in parallel:
ZT= Z / N
➢For two or more speakers connected in series:
ZT = Z x N

Appendix 10 |Wiring Instructions
Speaker Wiring:
▪For cable runs less than 2m between amplifier and speaker use 18AWG (1.0mm2)cable
▪For cable runs greater than 2m between amplifier and speaker, and for volume critical
installations, 15AWG (1.5mm2)cable is required
▪When two or more speakers are wired in parallel, use a separate pair of wires (rated as above)
directly from the amplifier to each speaker
Amplifier Wiring:
▪The power supply and ground/earth cables must be capable of carrying a current in excess of 30A
for 12V installations, and in excess of 15A for 24V installations. Wire thickness will depend on the
length of the cable run in each specific installation. The type and quality of wire used must also be
considered
▪The maximum cable thickness that can be fitted into the 6-pin connector is 12AWG (2.0mm2).
Two positive and two negative terminals are provided so that the current can be shared across
two wires
▪Where excessive runs are required, it may be necessary to run a single wire of sufficient thickness
close to the amplifier, and then divide the feed into two 12AWG (2.0mm2) wires
Other Wiring:
▪All other wiring to and from the amplifier and switched outputs must be selected giving the same
considerations as for the main feed cables
▪Where the siren is installed more than 2m from the vehicle battery the ground wire should be
connected to the nearest chassis point
▪Positive feeds over 2m must be extended using an adequate AWG size cable to prevent a voltage
drop exceeding 1V

The siren must be installed in a dry location and on a flat and even (ideally metal) surface. Ensure the
siren is kept away from any sources of heat and warm air and that airflow is not restricted (see Direction
of Airflow and Airflow Void). It is also important to allow access to the reset button and status LED
If the siren is to be installed vertically the cooling fan must be positioned uppermost

Wiring Looms:
When installing the siren, the wiring looms must be adequately secured in place using the cable ties
provided. The distance (mm) from the connector body to the cable tie must be observed as shown in the
images below
Looms should be smoothly formed and not at immediate right angles from the connector body as this will
put strain on the terminals and also risk disconnection from the siren
