Installation Notes
The LCS771 Siren Amplifier is a premium 200W unit designed for dual 100W speaker
use. It can be utilized with or without an optional hand held microphone (not
included with the LCS771-LM). The primary operating modes are haser, Yelp, Wail,
Hands Free, Manual, Alert, and Radio. A Noise Canceling A Override (when used
with optional microphone) and push-button Horn Override are available in all
modes. A manual push-button is provided for push-on/push-off tone toggle
operation in the haser, Yelp, and Wail modes. It also allows manual siren control in
the Manual or Alert modes. Any siren tone can be re-programmed to a more
desired tone. Another feature allows cycling through Wail, Yelp, haser, and
Standby by providing a signal to the horn ring auxiliary wire when the function switch
is in the Hands Free (HF) position. A ark Kill option is provided for connection to a
door switch, etc. to disable the siren when exiting the vehicle. Radio and A volume
controls are provided on the front panel. The front panel is backlighted with LED's
for night visibility. This compact unit utilizes short circuit, high voltage, low voltage,

Some municipalities may ban the use of specific tones, such as the Phaser tone.
Review the Optional Tone Programming feature described on the previous page to
reprogram the PHSR default tone from Phaser to any of the other tones listed.
Auxiliary-Manual Function Option
By default, when the siren is in PHSR, YELP, or WAIL modes, and the AUX function is
activated (typically by the steering wheel horn relay), the siren will produce the
standard Air Horn Tone (#1 in the Optional Tones list) and temporarily override the
siren tone. If you would rather have the AUX function (i.e. steering wheel horn)
mimic the MAN button (see MAN button functions on page 9), then you should
program the AUX function for tone #9 (Manual) or #10 (Mechanical Manual). To do
this, follow the procedure outlined on the previous page.

Operation
General
This unit is designed for easy
operation under the stress
associated with high-speed
pursuit. Most siren functions
are accessible with one
simple motion without
repetitive activation of
switches or automatic timed
switching that can interfere
with desired operation.
Power/PA Knob
The PA knob is located in the upper right hand corner of the
front face. It has two functions:
ON/OFF - This knob turns the siren on and off. While in
the OFF position none of the siren functions
will work. Also, the vehicle horn will function
normally, if connected properly.
PA Volume Control - This knob also provides you the ability to
adjust the public address volume. It should
be set when the vehicle is parked. Typically
you should set the A volume to the
maximum possible level with no feedback
(squeal).
Selector Switch
The rotary selector switch controls the primary operating function of the siren.
PHSR - Ultra-fast changing tone used for maximum attention.
YELP - A rapidly changing tone used in congested areas.
WAIL - A slower changing tone used on highways.
HF - Hands Free - A silent standby mode also known as Horn Ring Cycler.
Allows the user to cycle through the tones programmed for the WAIL,
YEL , HSR, and OFF by repeatedly pressing the horn or other switch
connected to the AUX input. Changing the rotary knob to any other
mode will resume normal siren operation.
MAN - A silent standby mode that allows push-button Manual, push-button Horn,
and ublic Address operation. The siren output winds down when the
MAN button is released.
ALERT - A silent standby mode that allows push-button Manual, push-button Horn
and ublic Address operation. The siren output terminates immediately
when the MAN button is released.
RADIO - Also known as Radio Repeat, this function amplifies a two-way radio
speaker input for re-broadcast outside the vehicle. The A remains
functional, but no siren tones are available in this position.

(Operation CONT’D)
MAN Button
Rotary Switch
Position Function When MAN Pressed
MAN or HF roduces a rising siren tone while being pressed. The siren
output “winds down” when the MAN button is released.
(Note: The MAN button has no effect when in HF mode and a
tone is active.)
ALERT Also produces a rising tone, but the siren output immediately
stops when the button is released.
PHSR/YELP/WAIL The MAN button will “step” the siren up to the tone programmed
for the next function:
(WAILYELPPHSRPhaser Step Up)
These quicker tones are used to momentarily alert motorists at
intersections and very highly congested areas. ressing the
MAN button once changes to the next faster tone. ressing the
MAN button again, reverts the siren back to the original tone.
HORN Button
ressing the HORN button provides a simulated air-horn tone while pressed. This can
be used to either replace or to supplement the normal vehicle horn and is useful at
intersections. This tone will override all other siren tones. See page 7 for
programming optional Air Horn tones.
The front panel of the LCS771 contains two
momentary push-button switches for the Manual
function and the Air Horn.
Slide Switch
The slide switch is designed for quick pursuit mode operation. The far left position
(OFF) will not activate any outputs.
Position  : Activates the first set of lights (connected to
Terminal 1 shown to the right).
Position  : Activates both the 1st and 2nd set
of lights (connected to Terminal 2
shown to the right).
Position  : Generally used for the FULL PUR UIT
MODE. It allows for quick activation
of both the lights and the siren in
one motion. When the slide switch
is moved to Position  , all three sets
of lights (connected to all 3
terminals) will activate and the siren
will go into WAIL mode.
Note: The auto-activation of the siren may be disabled or enabled for
other slide switch positions, if desired. (Refer to the DIP witch ettings
section on page 6).

Rocker Switches
6 lighted rocker switches
control the devices
connected to the
corresponding colored
wires described on
pages 2-5.
Radio Volume
The radio repeat volume (Radio) control is recessed in the
upper left hand corner of the front face. This should be set
when the vehicle is parked. First set the volume level of the
vehicle's two-way radio to its normal operating volume. Adjust
the siren's rotary selector switch into the RADIO position. Insert a
small, flat blade screwdriver into the RADIO volume adjustment
port. Turn in a clockwise direction to increase the sound level.
Auxiliary Input
The auxiliary input may be connected to the vehicle horn ring or other switching
device (see pages 2-4). It provides the same operation as pressing the HORN button
or can be programmed to function like the MAN button.
Park-Kill Cutout
During installation, the ark-Kill input may be connected to a door switch (see page
2). It will automatically turn off any siren tone when the door is opened. The siren
tone will continue to be cut off even when the door is closed. Changing any switch
or input will restore normal function.
Detachable Microphone (Included with LC 771 / Optional for the LC 771-LM) )
The microphone ( /N 30232-2) can be used
for public address operation. It will override
any siren tone when its push-to-talk (button on
the side) is pressed.
Connect the microphone to the adapter
harness (SWH-40). Review the diagram below
for proper pin layout. Note the ridge in the
connector.
The white amp connector can then be
attached to the corresponding
connector on the amp.
