Code 3 3599L5, Installation & Operation Manual

Page: 6 / 16

6. The unit is supplied with an eight-position, pluggable connector (color green) for the other connections. Insert the wire
into the connector and tighten the screw at these appropriate connector positions:
a. Speaker – the siren is designed to operate with one 11-ohm impedance speaker (100W) or two 11-ohm impedance
speakers (200W). Speakers are not included as part of the siren. Any 11-ohm 100W speakers for use with emergen-
cy vehicle may be considered to use. When using two speakers, they must be connected in parallel and in phase.
b. Horn Ring In and Out – The horn ring transfer circuit is capable of switching a maximum of 10 amperes. An external
relay is not required for horn ring operation. Locate the wire that connects the vehicle horn ring switch to the horn or
horn relay. Cut this wire. Connect a wire from “HORN RING IN” position on the connector to the horn ring side of the
wire that was just cut. Connect a wire from “HORN RING OUT” position on the connector to the horn side of the cut
wire. Properly insulate the wires. (Note: A footswitch may be substituted to use with “HORN-TAP” function. Connect a
wire to one end of the footswitch wire to the other end of the footswitch wires and the vehicle chassis.). The user has
the option for two different tone outputs when depressing the horn – Air Horn (default) or Manual. See the section
titled “Operation” for dip switch configurations.
c. Chassis ground – This wire should not be left unconnected. It is necessary to connect the siren enclosure to ground
and gain shielding effect. Use an 18-gause wire to connect the siren case to a good vehicle chassis point.
d. Door/Park-Siren-Off input – This feature automatically deactivates siren tones when the vehicle is shifted into PARK.
Lighting Level 3 will also “drop-out “ if this feature is enabled via the front panel dip switch. Siren tones will be disabled
until the vehicle is shifted out of PARK. This circuit is activated by a negative signal. Connect this input to a circuit that
is GROUNDED when the vehicle is shifted into PARK. It is the installer’s responsibility to determine an appropriate
location in the vehicle circuitry to connect this wire. See the section titled “Operation” for dip switch configurations.
e. Radio rebroadcast - Any line output signal with nominal one volt peak to peak can be connected here. If the output
seems to start distorted, reduce the radio gain by adjusting the “Radio Gain” trimmer on front of siren amplifier.
7. Plug the eight-position connector into the mating connector on the unit, and apply pressure until it locks into place.
8. To install the lightbar power wires, strip approximately 1/4″ of insulation from the end of the lights wires. Insert the wire
in the appropriate terminal of 7-position screw terminal block and tighten the screw. Keep in mind that terminals A, B,
and C have a 20 amp maximum current each, and terminals D, E, F, and G have a 10 amp maximum current each. The
total current of all 7 terminals is limited to 60 Amps,
9. Connect the +12V LTG wire directly to a 12V source. This connector provides power to the 3 Level, progressive light-
ing outputs and the 4 auxiliary outputs. This connection is designed to provide 60 amp service and therefore nothing
smaller than #4 gauge wire should be connected to it. If a fuse is installed, it should be sized for the actual load of the
lighting used and located as close to the battery positive as possible.
10. Ensure that there are no loose wire strands or other bare wire that may cause a short circuit. All wires must be protected
from any sharp edged that could eventually cut through the insulation. Also use an ohmmeter to verify that a short circuit
does not exist between the positive (+) leads and the vehicles chassis.
11. Perform visual check of all connections and wiring more before connecting the red wire to the positive (+) terminal and
black wire to the negative (-) terminal of the battery.
CONNECTION OF A 58 WATT SPEAKER TO THE SPKR TERMINAL WILL CAUSE THE SPEAKER
TO BURN OUT, AND WILL VOID THE SPEAKER WARRANTY!
