Wiring the Beta Series Siren Amplifier (9-position connector)
If the Beta series control head (optional) is not used, siren configuration and functionality are determined by user supplied switches
connected to the Beta amplifier. A brief explanation of each of the function wires of the 9 position connector will serve as a guide to help
determine the best configuration for your specific needs:
RED/WHITE Provides current for customer supplied switch operation (0.5 amp max.).
WHITE/GREEN Connects to a user supplied horn transfer switch (see schematic). This enables the vehicle horn ring to control the siren.
WHITE/BROWN Activates the Wail tone.
WHITE/RED Activates the Yelp tone.
WHITE/BROWN +
WHITE/RED Activates Piercer™ or Hi/Low tone.
WHITE/ORANGE Enables Hands-Free operation.
WHITE/YELLOW Activates Airhorn tone.
WHITE/RED +
WHITE/ORANGE Places Beta in Manual mode.
WHITE/BROWN +
WHITE/RED +
WHITE/ORANGE Places Beta in Radio mode.
Mounting the Beta™ Series Remote Siren Amplifier...
1.
Locate a suitable mounting location for the amplifier. The
trunk is often a good choice.
2. Be sure that the remote amplifier fits properly and does not
interfere with any parts of the trunk or seat back.
3. Position the remote amplifier on the proposed mounting
location. Using an awl or other suitable tool, scribe the
mounting surface where the mounting holes are to be
drilled.
CAUTION! As mounting the amplifier will require drilling, it
is absolutely necessary to make sure that no other vehicle
components could be damaged by the drilling process. If
any vehicle component could suffer any potential harm,
select a different mounting location.
4. Carefully drill the mounting holes using a #30 drill bit.
5. Using the supplied #8 x 5/8” sheet metal screws, secure
the remote amplifier to the vertical trunk wall.
Wiring the Beta Series Siren Amplifier (6-pos. connector)...
Connecting to Power
1.
Extend the RED and BLACK wires into the engine
compartment.
2. Follow the factory wiring harness towards your vehicle’s
battery.
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!
3. Connect the RED wire to one end of a user supplied fuse
block. Do not connect this unit to the battery yet!
4. Connect the BLACK wire directly to the vehicle’s chassis
ground (typically adjacent to the battery).
Connecting to your Speaker (100 watt):
1.
Route the ORANGE and BROWN wires towards your
speaker.
2. Connect the ORANGE wire to the POSITIVE (+) terminal
on the speaker.
3. Connect the BROWN wire to the NEGATIVE (-) terminal
on the speaker.
NOTE: The two (2) BLUE wires are used to connect your two-way
radio’s external speaker to the Beta amplifier for radio re-
broadcast. This is an optional connection and does not effect the
other operations of the Beta siren amplifier.
Wiring The Beta Siren Amplifier Radio Rebroadcast
Wires (BLUE)...
1. Locate the two wires that connect the external speaker to
the vehicle’s two-way radio.
2. Cut one of these wires and splice one of the BLUE wires
into this circuit.
3. Cut the remaining speaker wire and splice the remaining
BLUE wire into this circuit.
NOTE: Radio rebroadcast will NOT work with amplified
remote speakers! If your remote speaker is amplified
(contains a power amp circuit in the speaker assembly),
do NOT enable the radio rebroadcast feature.
