Hand Control: Choose a mounting location convenient to the operator and away from any air
bag deployment areas. Consider cable routing to amplifier. Mount the hand control with supplied
Hook and Loop tape (VELCRO). If the tape method is not preferred, the hand control may be
mounted several ways. A Holster (CP5 3) to hold the Hand Control or a Hanger and Holder to
hold the Hand Control like a microphone (ED1865) are available accessories.
See PARTS and ACCESSORIES Section.
O TION SWITCHES
An 8-position DIP switch on one side of the amplifier may
be changed to select various options.
Adjusting Option Switches - use a small screwdriver to
change switch settings.
The default setting is shown here. All switches are on.
SW-1 Auxiliary Input olarity - The auxiliary input is normally activated with positive. Turn
switch OFF for negative activation.
SW-4 Two-Tone - Turn this switch OFF to replace Phaser with Two-Tone.
SW-5 Horn Enable - Turn this switch OFF to disable Horn tone. Horn replaced with Yelp.
SW-4 & 5 Tone Disable - All siren tones may be disabled except Manual, Wail and Yelp by turn-
ing OFF both switches. Mechanical will be replaced with Wail. Phaser and Horn will be replaced
with Yelp.
SW-6 Short Manual - The Manual siren tone will normally fall and die out when released. Turn
this switch OFF to have Manual stop immediately.
SW-7 Manual Wail - Turn this switch OFF for Manual Wail instead of Manual Mechanical when
pressing the MAN pushbutton.
SW-8 Mechanical Fall - Turn this switch OFF for a quicker mechanical tone fall time.
HORN RING CYCLER 2 (HRC2) - Turn OFF DIP SW-2 and SW-3 to enable this feature. Also
connect the auxiliary input to the horn ring or other switch. While the siren is in standby, tap the
horn ring to bring the unit out of standby into Mechanical tone. Repeatedly tapping the horn ring
will cycle through Mechanical, Wail, Yelp, and Phaser tones. Tapping the horn ring twice quickly
will stop the siren tones and return the unit to standby. Pressing and holding the horn ring will
produce Horn tone until released. Then the siren will return to its previous siren tone or standby.
ELECTRICAL CONNECTIONS
Electrical connections to the unit are made using terminal block plugs and screw terminals located
on the amplifier. Labels on the unit identify each terminal function. Install the plug on the unit
before wiring. If the unit needs service the plug can be easily removed without unwiring. The
power supply of the unit must be capable of delivering peak currents up to 5 amps for adequate
short circuit protection and reliable operation. The preferred source is directly at the vehicle bat-
tery. The amplifier is fused.
Attach leads by stripping 3/8”, inserting into plug and clamp by tightening screw. Make sure the
screw is tight and the wire can’t be pulled out.
Failure to adequately tighten the screw can result in improper operation or burning the
connector and wire.
Wire Size and Termination - The diagram shows the minimum wire size used for each connec-
tion, along with recommended lead color. If the wire is longer than 1 ft. use the next larger wire
size. Use only high quality crimp connectors for installation on the vehicle.
SW-2 SW-3 Auxiliary Tone in Standby
ON ON (Default) Produces Horn tone while activated.
OFF ON Manual control of Mechanical tone.
ON OFF Manual control of Wail tone.
OFF OFF Activates Horn Ring Cycler 2 (HRC2) function.

CP52 8A 1/3/2
Enable Input Connection (ORG lead on wiring diagram) - This is NOT the same as the main
power connection. The enable input is like a power switch for the unit. When there is positive
power at this connection, the unit is powered up and ready to function. When power is removed,
the unit is not powered up and will not drain current from the battery. Connect to a positive circuit
controlled by the vehicle ignition switch, usually a terminal at the vehicle fuse panel. The required
current is low (15mA typ.).
Auxiliary Input Connection (Optional) - A momentary input typically connected to the horn ring
of the vehicle or other switch. See OPERATION section for auxiliary input functions.
NOTE: ermanent disconnection of the vehicle horn is NOT recommended.
The auxiliary input may be activated with positive or negative voltage. See Auxiliary olarity
under OPTION SWITCHES section for proper activation polarity. Input current is 1 to 2 mA.
Hand Control Connection - Route cable and plug into RJ12 jack on amplifier.

O ERATION
OWER ON/OFF
The unit is normally turned on with ignition switch on the vehicle. See INSTALLATION section.
The hand control will also be backlit.
SIREN CONTROLS
MECH, WAIL, YEL , AND HSR USHBUTTON SWITCHES
Four pushbutton switches control the primary operating mode of the siren.
The primary operating modes are:
Standby - A silent mode that may be overridden at any time.
Mech - A simulated mechanical siren tone. Tone may be changed or disabled. See OPTION
SWITCHES section.
Wail - A slower changing tone used on highways.
Yelp - A rapidly changing tone used in congested areas.
haser - A very rapid changing tone used at intersections and very highly
congested areas. May be optionally replaced with Two-Tone or disabled.
Two-Tone is two alternating frequencies like a European HI-LO. See OP-
TION SWITCHES section.
Momentarily press button to activate (lit red). Momentarily press button
again to de-activate. Also while a particular mode is activated, switch to a
different mode by pressing one of the other three buttons. The unit is in
Standby when NONE of the four buttons are activated (NOT lit red). For
example starting with all four buttons off, press the Wail button to turn on
Wail. Now press the Yelp button to change to Yelp. Press the Yelp button
again to turn off sound (return to Standby).
When Mechanical or Wail is turned off the tone will die out. Turn on Short
Manual option to stop tone immediately. See OPTION SWITCHES section.
MAN USHBUTTON SWITCH
Provides manual control of siren tone depending on the primary operating
mode selected.
While in Standby, the Manual button controls the Mechanical tone. Rising to peak while pressed
then falling until die out when released. May be optionally replaced with manual Wail tone.
See OPTION SWITCHES section.
While in Mech, Yelp, or Phaser mode, pressing the Manual button causes tone to rise and peak
then resume when released. While in Wail mode pressing this button toggles between Wail and
Power C tone.
HORN USHBUTTON SWITCH
Produces a simulated Air-Horn tone while pressed. Overrides all siren modes. Horn tone may be
disabled. See OPTION SWITCHES section.
AUXILIARY IN UT FUNCTIONS
The switch or horn ring attached is intended to be momentary. While in Mech, Wail, Yelp, or
Phaser mode, activating auxiliary will produce Horn tone. While in Standby, activating auxiliary
will normally produce Horn tone. Different tones are available. See OPTION SWITCHES section.
Horn Ring Cycler 2 (HRC2) - this feature may also be added. See description on Page 4.

SERVICE
This unit is designed to provide years of reliable service under even the worst conditions. Many
times there may appear to be a problem with the unit when the true problem is in the speaker,
controlled devices, or improper installation. The following chart shows typical symptoms and
possible causes.
A blown siren fuse doesn't necessarily mean that the unit is bad. If a speaker or speaker lead is
shorted the fuse will blow before the unit is damaged. Disconnect the SPKR leads and replace
the fuse. If the amplifier makes noise with Wail mode selected and Enable Input powered the
amplifier is OK. Check the speaker or leads for possible shorting.
