General Description
The LCS800 series is a premium remote system that combines the siren amplifier, the
siren controls, and light controls all in one system. A single slim-line remote control
head combines the noise-canceling microphone with a built in siren, as well as
many of the switch and light controls for the ehicle. The control head contains
illuminated switches that change color to indicate status. The face of the control
head is sealed around e ery push button to help pre ent liquid from entering the
electronics. The amplifier is a 200W siren amplifier unit designed for single or dual
100W speaker use. The LCS850 model adds full arrow stick controls.
The control head contains se eral distinct controls for operation of ehicle de ices.
The slide switch allows quick pursuit mode operation. The far right slide position can
be set up to acti ate maximum lights and siren for pursuit mode. Fi e push buttons
allow control of fi e different lighting or auxiliary functions. Se en additional push
buttons allow full siren operation. The LCS850 also adds control of an arrow stick.
The LCS800 series is designed to allow maximum ersatility in mounting. The control
head is remote from the siren amplifier and light relay control box, creating a
compact user interface that can be mounted onto the dashboard, o erhead, or in
the center console. The amplifier box and arrow stick control box can then be
mounted remotely in the trunk, under the dashboard, under the seat, or where er
con enient. The control head is a ailable with an adjustable “U” bracket or with a
flange for recessed mounting.
Siren operating modes include Wail, Yelp, Phaser, Hands Free, and Radio. A Noise
Canceling PA O erride is a ailable in all modes. A Manual button allows tone
toggle operation and manual siren control. The Air Horn button will o erride any
siren tone. The ehicle horn switch may also perform the Manual push button
function ia an auxiliary input. Twel e option jumpers allow the unit to be fully
customized to the operators' needs. Options include: Phaser s. Two-Tone, Phaser
disable, 8 second timed gunlock release, momentary s. lock-on/lock-off switch
operation, N.O. contact s. N.C. contact, auto horn ring transfer, and many more.
A Park Kill option is pro ided for connection to a door switch, etc. to disable the siren
when exiting the ehicle. Both a PA olume and a Radio olume are pro ided.
The LCS800 series has been designed with se eral protection features to pro ide
exceptional field ser ice. Excessi e high or low oltage detection will disable the
siren output, protecting both the amplifier and the speaker. Fused inputs pro ide
safety against re erse polarity. Speaker diagnostics pro ides user feedback as well
as shutdown protection against speaker opens and shorts. The first four light output
functions are indi idually protected with 20A fuses, while the fifth light output
function is protected with a 2A in-line fuse. CAUTION: These protection features will
not guard against o erloading the outputs.
There are currently four different sirens in the LCS800 series:
LCS800-008 Standard ersion with slide switch, full siren controls, and light
controls. Includes a remote head with microphone, the siren
amplifier, and switch relay box.
LCS800-F8 Flange mount ersion of the standard LCS800
LCS850-8 Enhanced ersion with all the standard controls plus arrow
stick controls. Also includes the arrow stick control box.

W RE S ZE AND TERM NAT ON
• The wiring diagrams on pages 13 and 17 show the minimum wire size used
for each connection, along with recommended lead color.
• If the wire is longer than 10 ft., use the next larger wire size.
• Use only high quality crimp connectors.
• Make sure all connections are tight.
• Route wiring to pre ent wear, o erheating and interference with air bag
deployment.
• Use grommets and sealant when passing through compartment walls.
• Minimize the number of splices to reduce oltage drop.
• Ground connections should be made directly to the negati e of the ehicle
battery. If not possible, connect only to substantial chassis components.
• Install and check all wiring before connection to ehicle battery. SEE TABLE
BELOW FOR CORRECT WIRE SIZING!
• All conductors should be constructed of stranded copper with
thermoplastic insulation.
CAUT ON: All wires should be rated for at least 125% of their maximum current load.
All wires connected to the positive terminal of the battery should be fused at the
battery for their rated load. The load can be calculated by adding all lamp
wattages and di iding by 13. Load (Amps) = Total Watts / 13 olts. Do not use 1/4"
diameter glass fuses, as they are not suitable for continuous duty abo e 20 amps.
S REN AMPL F ER
Communication between the control
head and the amplifier is made ia a
communications cable using an RJ11
jack located on the opposite side of
the power connector. CAUTION:
Please note that the cable used IS NOT
a standard telephone cord and
CANNOT be replaced with one.
Make all electrical connections to the power connector before installing the
connector on the unit.
If the unit needs ser ice, both the communication cable and the power connector
can be easily remo ed without unwiring the connector.

-12-
(Electrical Connections: Siren Ampli ier CONT’D)
Siren electrical power connections to
the amplifier are made using a
remo able connector located on the
back of the amplifier case.
The power supply to the siren unit must
be capable of deli ering peak currents up to
50 amps for adequate short circuit protection
and reliable operation. The preferred source
is directly at the ehicle battery. The unit is
internally fused. The wiring diagram on the next page shows detail of how to wire
the connector on the amplifier to the ehicle.
Make all electrical connections to the power connector before installing the
connector on the unit.
Siren Wiring Connections:
BLACK LEADS: (GROUND) - Connect BOTH black wires to the negati e of the battery, or
to a good chassis ground. Be sure to use minimum size #14 AWG wire.
RED LEADS: (POWER/+12VDC) - Connect BOTH red wires to the positi e of the
battery, or to a high current power buss. Be sure to use minimum size #14
AWG wire.
BROWN LEADS: (SPEAKER) - Connect one lead to each terminal or lead of the speaker.
f connecting a second speaker in parallel, you must observe the polarity
of the speakers (phasing). Be sure that the positive terminals of both
speakers are connected together to the same brown wire from the siren.
PINK LEAD: (IGNITION SWITCHED POWER) - Connect the pink wire to your ignition-
controlled power (or other switched power source). This will turn the
power to your unit on and off.
Siren Optional Connections:
BLUE LEADS: (RADIO REPEAT) - Connect one blue lead to each terminal of the two-
way radio speaker or output connector of the radio. Use #18 AWG wire.
GREEN LEAD: (AUX) - Use if you would like to acti ate the siren’s AIR HORN when the
ehicle horn is pressed. Connect to horn ring circuit or other remote
switch. Circuit may be positi e or negati e with proper jumper selection.
See Auxiliary nput Polarity section on page 3 for jumper details. NOTE:
Cut lead short if not used & insulate with electrical tape.
Optionally this may be used to mimic the Manual button function when
the ehicle’s horn is pressed. See Auxiliary control on pages 6-7 for
Control Head jumper setting.
WHITE LEAD: ((PARK-KILL) - Connect to dome light or added door switch. Circuit may
be positi e or negati e with proper jumper selection. See Park Kill nput
Polarity section (page 4) for jumper details.
NOTE: If not used, cut lead short and insulate with electrical tape.
ORANGE LEAD: (HORN RING TRANSFER or LOW CURRENT OUTPUT) - You only need to
connect this wire if you will also be connecting the green AUX wire to
your horn ring circuit, thus enabling the driver to control the siren
functions by using the vehicle horn. This output is controlled by
pushbutton switch S5 and it temporarily deacti ates the ehicle’s horn.
This allows the use of the horn ring switch without actually sounding the
ehicle’s horn.
Connect the Orange wire to the Horn Ring Transfer Relay as shown the
HRT Wiring Diagram on page 14.
NOTE: If not used, cut lead short and insulate with electrical tape.

The following steps are recommended when installing, to help reduce RFI:
1. Make sure that both the control head and amp are securely attached to good
chassis ground (i.e. no paint in-between the chassis and the grounding
terminal).
2. Keep the siren control head and amplifier as far away from the police radio as
is practical.
3. Check that the police radio antenna wire makes a right angle from the back of
the police radio and runs on one side of the ehicle. The communications
cable for the siren should make a right angle out of the back of the control
head and exit in the opposite direction from both the police radio antenna wire
and the police radio power wires.
4. Excess communication cable from the control head to the amp should be
tightly bound back near the amplifier box.
5. One of the RFI chokes (STAR P/N: P30039-57) should be placed around the
communications cable at the back of the siren amplifier box.
6. The second RFI choke should be placed around the Red and Black wires exiting
the siren amplifier box.

The electrical connections for input power, slide switch outputs, and the push button
outputs are made to the control box (amplifier) using terminal blocks (top diagram
above).
nput Power: (Left Terminal Block) Connect +12VDC to the 3 large barrier
style terminals. When controlling lights with a large amount
of current (>15A) power should be supplied to all three
inputs.
Slide Switch Outputs: (Center Terminal Block) Connect the lights that you wish to
acti ate in the corresponding slide switch positions to the
L1, L2, and L3 outputs (20A max each). (Note: t e second
slide switc position activates bot L1 and L2 and t e t ird
slide switc position activates L1, L2, and L3).
Push Button Outputs: (Rig t Terminal Block) Connect the lights that you wish to
acti ate with corresponding pushbutton switches S1-S4 to
the S1-S4 outputs (20A max each).
S5 Output: Push Button S5 switches low current power (2A or less) to the
Orange wire in the wiring harness. It has an in-line 2A fuse.
Typically the horn ring transfer relay is connected to this
switch. This output should be connected to an external relay
if more than 2 amps is required.
