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.
ON/OFF
The On/Off-PA volume control (PA) will both turn the
LCS770 unit on and off, as well as control the public address
volume. It is located in the upper right hand corner of the
front face. When the unit is not in use, you may elect to leave
this switch in the OFF position. To turn the unit Off, rotate
the switch counter clockwise until it clicks. This will power down the unit and
will prevent accidental activation of any of the controls on the face of the unit.
Rotating the knob clockwise will power up the LCS770. THIS SWITCH MUST
BE TURNED ON FOR ANY OF THE FUNCTIONS TO WORK.
LIGHT SLIDE SWITCH
The slide switch is designed for quick pursuit mode operation. The far left position
(OFF) will not activate any outputs. Position 1 will activate the first set of lights
(connected to L1). Position 2 activates both the first and second set of lights
(connected to L1 and L2). Position 3 activates all three sets of lights (connected to
L1, L2 and L3), along with the siren. Each output is protected with a 20A fuse.
Pursuit Mode - Position 3 (farthest right) is generally used for the full pursuit
mode. It allows for a quick procedure that will activate both the
lights and the siren in one motion. When the slide switch is
moved to Position 3, all three sets of lights will turn on and the
siren will activate into the Wail mode.
The siren may be disabled in the pursuit mode during installation
if desired. (Refer to the section on page 4 under INSTALLER
SELECTABLE OPTIONS).
