REMOTE - Connect to the Remote terminal on the Siren Amplifier Connector.
Lighting Models Only ( L versions )
#8 GAUGE RED WIRE PIGTAIL - provides power to the 3 Level, progressive lighting outputs only.
The wire can be ordered with an optional connector to allow for convenient removal. The connector
should be soldered to each wire, NOT crimped. This connection is designed to provide 50 amp
service and therefore nothing smaller than #8 guage wire should be connected to it.The circuit breaker
used should be sized for the actual load of the lighting used and located as close to the battery
positive as possible. For quick disconnection option on 8 AWG wire see "lighting switch connector"
on page 23.
4 Position Screw-type Terminal Block Connector
Important!
The total combined current for the auxillary outputs A,B,D on L4 models and A,B,D,E,F on L6
models must not exceed 30 Amps total.
+12VAUX - Connect to the positive terminal of the battery with 30 Amp circuit protection. Locate the
fuse or circuit breaker at the battery and use #10 gauge wire minimum. This terminal powers
switches A,B and D on L4 models and A,B,D,E and F on L6 models, and also supplied power to the
siren lock & light alert circuits on both models.
LEVEL 1 - Connect to the first level of warning lights (Green LED) position "1" on level switch.
LEVEL 2 - Connect to the second level of warning lights (Yellow LED) position "2" on level switch.
LEVEL 3 - Connect to the third level of warning lights (Red LED) position "3" on level switch.
NOTE: LEVEL 1, LEVEL 2, LEVEL 3, switch progressively. Switch position 1 provides +12 volts at
Level 1 terminal. Switch position 2 provides +12 volts at terminals 1 and 2. Switch position 3
provides +12 volts at terminals 1, 2, and 3.
SET-UP AND ADJUSTMENT
All of the adjustments, except MAXIMUM P.A. ADJUSTMENT, and set-up switches are
accessible from the rear of the unit. Make these adjustments and position the set-up switches prior
to placing the unit inside their bail bracket (see wiring diagram, page 20).
Audio Adjustments
Radio Rebroadcast Adjustment - Place the selector switch in the RADIO position. The trimmer
located on the rear panel of the siren sets the maximum level RRB will reach with the knob fully
clockwise. To adjust properly, set the volume knob fully clockwise and adjust the trimmer such that
normal two-way radio volume inside the vehicle produces the desired volume outside the vehicle.
Maximum P.A. Volume Adjustment - This trimmer ( located on the front panel next to the volume
control knob ) sets the maximum level that the P.A. volume will reach with the front panel VOLUME
control in the fully clockwise position.To adjust properly, set the front panel volume control fully
clockwise and adjust the trimmer while keying the microphone until the maximum volume out of the
speaker is such that there is no feedback and is intelligible. (See Figure 1)
