General Description

The ST300 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 vehicle. The control head contains illuminated switches that change color to indicate status. The face of the control head is sealed around every push button to help prevent liquid from entering the electronics. The amplifier is a 200W siren amplifier unit designed for single or dual 100W speaker use.

The control head contains several distinct controls for operation of vehicle devices.

The slide switch allows quick pursuit mode operation. The far right slide position can be set up to activate maximum lights and siren for pursuit mode. Five push buttons allow control of five different lighting or auxiliary functions. Seven additional push buttons allow full siren operation.

The ST300 series is designed to allow maximum versatility 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, overhead, or in the center console. The amplifier box can then be mounted remotely in the trunk, under the dashboard, under the seat, or wherever convenient. The control head is available with an adjustable “U” bracket or with a flange for recessed mounting.

-1-

(General Description CONT’D)

Siren operating modes include Wail, Yelp, Phaser, Hands Free, and Radio. A noise canceling PA override is available in all modes. A Manual button allows tone toggle operation and manual siren control. The Air Horn button will override any siren tone.

The vehicle horn switch may also perform the Manual push button function via an auxiliary input. Twelve option jumpers allow the unit to be fully customized to the operators' needs. Options include: Phaser vs. Two-Tone, Phaser disable, 8 second timed gunlock release, momentary vs. lock-on/lock-off switch operation, N.O. contact vs. N.C. contact, auto horn ring transfer, and many more. A Park Kill option is provided for connection to a door switch, etc. to disable the siren when exiting the vehicle. Both a PA volume and a Radio volume are provided.

The ST300 series has been designed with several protection features to provide exceptional field service. Excessive high or low voltage detection will disable the siren output, protecting both the amplifier and the speaker. Fused inputs provide safety against reverse polarity. Speaker diagnostics provides user feedback as well as shutdown protection against speaker opens and shorts. The first four light output functions are individually 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 overloading the outputs.

All conductors should be constructed of stranded copper with thermoplastic insulation.

CAUTION: 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 dividing by

13. Load (Amps) = Total Watts / 13 volts. Do not use 1/4" diameter glass fuses, as they are not suitable for continuous duty above 20 amps.

SIREN AMPLIFIER

Siren electrical power connections to the amplifier are made using a removable connector located on the back of the amplifier case.

Communication between the control head and the amplifier are made via a communications cable with an RJ11 jack.

CAUTION: Please note that this cable IS NOT a standard telephone cord and CANNOT be replaced with one.

You should make all electrical connections to the power connector before installing the connector on the unit.

If the unit needs service, both the communication cable and the power connector can be easily removed without unwiring the connector.

-12-

(Electrical Connections CONT’D)

The power supply of the siren unit must be capable of delivering peak currents up to 50 amps for adequate short circuit protection and reliable operation. The preferred source is directly at the vehicle battery. The unit is internally fused.

The wiring diagram on the next page shows detail of how to wire the power connector on the amplifier to the vehicle. The communication cable should have one end plugged into the amplifier (telephone style jack) and the other end plugged into the control head.

Siren Wiring Connections:

BLACK LEADS: You MUST connect BOTH black wires when using two 100W driver speakers.

Connect to the negative of the battery, or to a good chassis ground. Be sure to use minimum size #14 AWG wire.

RED LEADS: You MUST connect BOTH red wires when using two 100W driver speakers. Connect to the positive of the battery, or to a high current power buss. A power relay may also be used. Be sure to use minimum size #14 AWG wire.

BROWN LEADS: Connect one lead to each terminal or lead of the speaker. Be sure to use minimum size #14 AWG wire . If 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 . In which case, the negative terminals of both speakers would also be connected together to the other brown wire.

PINK LEAD: Connect the pink wire to you ignition-controlled power (or other switched power source). This will turn the power to your unit on and off.

Siren Optional Connections:

BLUE LEADS: Use for radio repeat. Connect one blue lead to each terminal of the radio speaker or output connector of the radio. Use #18 AWG wire.

GREEN LEAD: (AUX) Use if you would like to activate the siren’s AIR HORN when the vehicle horn is pressed. Connect to horn ring circuit or other remote switch. Circuit may be positive or negative with proper jumper selection. See Auxiliary Input Polarity section on page 4 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 vehicle’s horn is pressed. See Auxiliary control on pages 7-8 for Control Head jumper setting.

WHITE LEAD: Used for Park Kill (Cut-off). Connect to dome light or added door switch. Circuit may be positive or negative with proper jumper selection. See INSTALLER-SELECTABLE

OPTION section (page 4) for jumper details.

NOTE: Be sure to cut lead short if not used and insulate with electrical tape.

ORANGE LEAD: Used for Horn Ring Transfer Relay, or other low current output. This output is activated by pushbutton switch S5. Optionally it can be ON at siren boot (see Activate

Horn Ring Transfer on start-up on pages 7-8). The HRT will deactivate the vehicle’s horn when it is on (S5 on). This allows the driver to use the horn ring to control the siren without activating the vehicle’s horn.

Connect the Orange wire to the Horn Ring Transfer Relay or other low current device

(Maximum 2A) . This output may also be used to drive an external relay when higher current is required. NOTE: Cut lead short if not used & insulate with electrical tape.

Operation

GENERAL

This unit is designed for easy operation under the stress associated with high-speed pursuit. Most light and siren functions are accessible with one simple motion of the slide switch.

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 1st and second set of lights (connected to L1 and L2).

• Position 3 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 , the following will activate:

All three sets of lights (Connected to L1, L2 and L3 - Each output is protected with a 20A fuse)

The siren (Wail mode)

• Position 3: The siren may be disabled in the pursuit mode during installation if desired.

(See page 6 of the INSTALLER-SELECTABLE OPTIONS section for jumper details.).

-19-

(Operation CONT’D)

The seven push buttons across the middle of the control head allow full siren operation. When not activated, these buttons are backlit in green for nighttime viewing. When activated, an audible beep is heard, and the backlighting turns red.

MAN (Manual )

In stand-by (no tone) or in the Hands Free Mode, this momentary push button switch provides a manually activated Wail siren tone while being pressed. With the Wail, Yelp, or Phaser mode selected, this switch provides a generally quicker changing tone. (See tables on next page). These quicker tones are used to momentarily alert motorists at intersections and very highly congested areas. Pressing the button once changes to the next faster tone.

Pressing the manual button again, reverts the siren back to the original tone.

Optional configuration allows the replacement of the Phaser tone with Two-

Tone, or the disabling the Phaser tone entirely. These options are selected during installation and may be governed by State or Local laws. (See page 5 of the INSTALLER-SELECTABLE OPTIONS section for jumper details.) .

HORN (Air Horn)

This momentary push button switch 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 or in high noise areas. This tone will override all other siren tones.

HF (Hands Free)

Also known as Horn Ring Cycler, allows the user to cycle through Wail,

Yelp, Phaser, and Standby by repeatedly pressing the horn or other switch connected to the AUX input. Operating any other mode resumes normal operation. Please note that this mode disables the Manual (MAN) push button selection when a Wail, Yelp, or Phaser tone is cycled to.

WAIL

A normal rise-fall tone used on highways and areas with low traffic or constant traffic flow.

YELP

A rapid warble tone used in light to moderately congested areas.

PHSR (Phaser)

Ultra-fast warble one used for maximum attention in highly congested areas.
