Safety Information:
Sirens are produced in 12 and 24 Volt versions. Ensure that you have the correct version for your
installation.
A suitable fuse and holder is provided with the siren amplifier wiring loom where bought.
Otherwise the recommended fuses are: 15A fuse –12V version and 7.5A fuse –24V version.
The Siren amplifier should be installed by an electrically competent person in accordance with
the fitting instructions.
Any wiring to or from the siren should be sufficient to carry the load, loads are given on page 6,
there is also a wire size selection matrix on page 9 which may aid this.
Sirens may get hot in use and they should be sited where this will not cause any hazards.
Consideration should be given to allowing air flow over the amplifier.
This equipment generates high levels of sound which may be detrimental to hearing. Care
should be taken during installation and testing so as to avoid endangering yourself or others.
Use of this equipment does not guarantee right of way over other road users and may not
always be heard by them. It should be operated only by trained and competent personnel.

9004 SERIES
SIREN AMPLIFIER

Features:
Horn polarity detection –The siren amplifier detects if the horn is positive switched or negative
switched on start up. The HRT wire (pin 9) should be connected to the switched side of the horn (see
page 9 for full details).
Data output –This provides a 200mA positive output feed that can be connected to a data logger, the
data output is switched on when the siren is sounding and operating correctly.
Relay output –This provides a 200mA positive output feed that can be used to connect to a separate
relay (available separately) so that the Horn can be bypassed when the siren is operating.
This output is active when either the tone is sounding or when the run input is selected (see page 9 for
an example of the wiring).
Fault LED –The siren amplifier has a fault LED incorporated into the front panel to aid debugging and
trouble shooting of any faults. The LED will flash in different patterns to identify a particular fault (see
page 11 for fault codes and troubleshooting).
Circuit protection –The siren amplifier has the following protective circuitry incorporated into it to
ensure that fitting errors don’t cause damage to the siren or vehicle systems as well as:
Start delay –the siren will not work until three seconds after power is first applied to the
siren amplifier to allow voltage to stabilise after engine started, stopping damaging voltage
transients effecting the speaker.
Reverse Polarity protection –if the positive and ground lines have been reverse wired the
siren will not function, however the siren amplifier and speaker will not be damaged by this.
Over temperature protection –In the event of the siren overheating through excessive
prolonged use or extreme ambient temperatures. The siren will switch off the siren output
until it has cooled sufficiently to resume operation.
Over current protection –if the siren amplifier circuit is drawing too much current, caused
by a speaker failing or short circuit, the siren will switch off the siren output. The power to
the siren amplifier will have to be reset to clear this fault.
Speaker short circuit protection –if a short circuit is detected on the speaker the siren
output will switch off. The power to the siren amplifier will have to be reset to clear this
fault.
Over and under voltage protection –if the operating voltage is out of operating parameters
for the voltage version of the siren, the siren will not operate. i.e. when 12V siren fitted to
24V vehicle or if the vehicle battery is flat.

Software description:
INTERLOCK
The interlock input needs to be connected to a positive voltage source for the tone to be able to
sound, such as a beacon interlock device. If not used connect to battery positive to enable tones.
HORN / FOOTSWITCH INPUT
Providing that the interlock input is connected to a positive voltage source, and that the siren isn’t
already sounding. Pressing the horn or footswitch will play a single sequence of the selected tone.
RUN INPUT
Connecting this to battery negative will cause the siren to play the selected tone, while connected,
providing that the interlock input is connected to a positive voltage source. Such as a beacon interlock
device or battery positive.
TOWN / COUNTRY SOUND SELECT INPUT
When this input is disconnected the Town sound will play (without vibrato) when selected either by
pressing the horn or connecting the run input to battery negative.
When this input is connected the Country sound will play (with vibrato) when selected either by
pressing the horn or connecting the run input to battery negative.

Positive & Negative HRT detection:
The Siren amplifier detects if the horn ring transfer is positive or negative switched at start up.
If the HRT input senses a positive feed it must be a negative switched horn, if it doesn’t sense a positive
feed it must be a positive switched horn. The HRT input just needs to be connected to the switched
side of the vehicle horn for the detection to work.
Occasionally there can be a problem when fitting over the top of an old system where a positive to
negative HRT change over relay has been fitted. As the siren amplifier is looking for a positive feed
when the horn is not pressed and no feed when the horn is pressed. Either connecting the positive
horn feed directly to the HRT input or wiring the relay as shown below should resolve this issue.
Wiring a horn bypass relay:
The diagram below shows how to connect the HRT input and relay output of the siren amplifier to
additional components to act as horn by pass for either a positive or negative switched horn.
Recommended resistor value: 10K, 0.25W, radial.

Day & Night Volume Switching
Below are two different wiring possibilities for wiring a switch to control the siren output for day and
night volume levels.
Day and night switching using relay Day and night switching using SPDT Switch
SPDT switch PH PN: 502
Note: SPDT switch can be used for both operations, when using SPDT switch it must be rated correctly
for the current passing through it (6A).

Wire Crimping
It is the purchaser’s responsibility to use a compatible crimping tool when fitting wire crimps ( PH part
No. 504304, manufactured by T.E. Connectivity, Man part No. 794956 –1 ), to ensure correct quality
of crimp connections.

Fault Codes:
When the siren amplifier detects a problem with its operation it flashes the fault LED on the front of
the unit, fault patterns below. The fault light should be treated as a warning of improper operation and
possible causes should be investigated. The trouble shooting table below may assist with this, note this
is not intended to be an exhaustive list and is a guide only all work should be carried out by an
electrically competent person.

Wait for siren to cool and operation should resume.
Check that siren has sufficient air gap to allow for air
flow.
Ensure that siren is fitted away from other equipment
that may get hot.
Under Voltage fault indicated
Check battery voltage (may be below 11V)
Check correct voltage version of siren is fitted
Check cabling is rated correctly (if under rated may have a
voltage drop down line)
Check ground return to battery (ground could be
unstable)
