Installation and Operation Read and observe the Safety
Instructions provided for these products.
Power Connection Amplifiers are produced in 12 and 24 Volt versions.
Ensure you have the correct version for your installation. If connected to the
wrong voltage no damage will occur but the amplifier will fail to work. They
are designed for permanent connection to the battery. Power should be
routed directly from the battery. A suitable fuse and holder is provided with
the siren power loom. (12 volt sirens – 20 Amp; 24 volt sirens – 10 Amp.)
When first connected to power the amplifier takes a few seconds to initialise.
Operational Switch (Similar to Master Switch – intended to be used at
beginning and end of shift.) Any low current switch can be used as the
operational switch. Install a switch on the red link wire on the 20 way
connector. If you wish to use the vehicle ignition as the switch, break the link
wire and feed positive from the vehicle ignition circuit to the red wire on
pin 17. The siren will not run until this switch is on and will take a few
seconds to initialise following switch on.
Location The siren may become hot in use. Leave room for air flow around
it, particularly in the region of the fan. The amplifier is not waterproof.
Loudspeakers Select the correct output for your loudspeaker by fitting the
brown wire with the white stripe into the correct hole on the 20 way connector.

panels utilise them for tone pre-selection or remote activation of the Air Horn
sound. If so this will be specified in the Data Sheet which you should consult
for a full explanation of the exact operation. In use they are activated by
connecting to chassis (pin 13) via a suitable switch.
Radio Re-broadcast facility
Connect the two blue input wires from pins 5 & 15 (Grey wires from pins 4 &
14 for “Radio 2”) to the radio loudspeaker terminals. Polarity is not important.
Volume of playback depends on both radio and panel volume controls as well
as the electronic preset control. The 9 step preset control is instead of the
traditional trimmer that was adjusted by a screwdriver and is set up at the
Control Panel. It can be set to different levels for Radio 1 and Radio 2 inputs.
Consult the Data Sheet for your Control Panel to see how to adjust the preset
level. Once set the level is stored in the amplifier.
If you replace the amplifier in the course of maintenance it will
be necessary to re-set the preset levels at the Control Panel.
If used for re-broadcast of continuous signals (e.g. broadcast radio), the
amplifier may shut down to avoid overheating. In this event, reduce the
position of the volume setting until this ceases to happen.
Protection Devices
The power amplifier is protected against overheating or short circuits on the
output. In the event of either, the amplifier will shut down and the Fault lamp
on the front of the Power Amplifier housing will illuminate.
Maintenance Tip
A short circuit is most likely due to a loudspeaker, which has shorted or
is starting to short. To confirm this disconnect the loudspeaker wire,
then turn the amplifier On. If the fault lamp does not illuminate when the
siren is operated then the loudspeaker circuit is at fault; if it still
illuminates the amplifier itself is faulty.
In the case of a short circuit the Fault lamp may be cancelled
immediately, whereas for overheating the amplifier must have cooled
down sufficiently first.
Data Logger Output
A 12 / 24 volt signal is output on the pink wire (pin 12) when the siren is
generating a tone and the loudspeaker is functional. Maximum output current
is 0.2A.
Beacon Interlock Input (White wire, pin 18. Applicable only if specified on
Data Sheet, leave disconnected otherwise.) Tones will not sound until this
input receives a positive signal (+12 / 24 Volts). It should be used in
conjunction with the appropriate Interlock device for full interlocking, or it may
be taken direct to the switched output of your Beacon switch for a basic
interlock. If your model has an interlock but you do not require one simply
take this wire to a permanent positive source. (e.g. Pin 16 which is also
fused.) This will not draw any standby current.

Accepts a 12 / 24 volt signal to control the back lighting and dim the function
lights on the Control Panel (e.g. 8006 microphone). Connect to the vehicle
dash lighting circuit. If you do not require this facility or the Data Sheet for
your Control Panel specifies this as “Not used” simply leave it disconnected.
