Park Kill Input Polarity The Park Kill (Cutout) Input turns off any siren tone output when activated, and remains off until a control is activated or changed. The wiring diagram on page 11 shows two connection examples. The park kill input is normally activated by connecting to positive. To activate by connecting to ground (negative), move the “PKILL”...

Auxiliary Input Function The Auxiliary Input allows activation by an external source of either the Horn or the Manual push-button functions when the rotary selector switch is in the Manual, Alert, or Hands Free (HF) position. This input is usually wired into the vehicle horn switch.
Never operate this unit without adequate hearing protection for you and others. in the area. (OSHA 1910.95) AMPLIFIER The SS730 amplifier should be mounted in a location such as the driver compartment firewall, under the seat, or in the trunk. It is not recommended to mount the amplifier in the engine compartment or in an area that would be allowed direct exposure to weather elements.

CONTROL HEAD Please note that for the SS741MG-TEC the 7 -position knob functions are reversed. The control head is designed to be flush mounted. Select a location such as the dash, the overhead console, or a center console. Choose a mounting location convenient to the operator and away from any air bag deployment areas.
ELECTRICAL CONNECTIONS AMPLIFIER 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 special communication cable. CAUTION: Please note that this cable IS NOT a standard telephone cord and CANNOT be replaced with one.

Wire Size and Termination The wiring diagram on the next page shows the minimum wire size used for each connection, along with recommended lead color. Please use the following guidelines when wiring your siren: • If the wire is longer than 10 ft. use the next larger wire size. Use only high quality crimp connectors.
OPERATION GENERAL Please note that for the SS741MG-TEC the 7 -position knob functions are reversed. 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.
SELECTOR SWITCH The rotary selector switch controls the primary operating function of the siren. PSHR (Phaser)- Ultra-fast warble tone used for maximum attention in highly congested areas. YELP - A rapid warble tone used in light to moderately congested areas . Please note that for the WAIL - A normal rise-fall tone used on highways and SS741MG-TEC the 7 -position...
With the selector switch in the Manual, Alert or Hands Free position this momentary push-button switch provides a manually activated Wail siren tone. While the selector switch is in the Wail, Yelp, or Phaser position, this switch provides a generally quicker changing tone. (See tables below and on next page). These quicker tones are used to momentarily alert motorists at intersections and very highly congested areas.
VOLUME CONTROLS RADIO REPEAT VOLUME The radio repeat volume is recessed on the front face of the amplifier next to the communication jack. 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.
TROUBLESHOOTING Symptom Possible Cause Check No power Power switch not turned on Does back-lighting come on? Connector loose Do you hear a “pop” when turned on? Amplifier 20A fuse blown Is power hooked up backwards? Positive ground vehicle? Is an external fuse or circuit breaker used? Loose connection at power source Are the negative leads connected to a good ground?
If you are experiencing an unusually high amount of RFI, you may perform the following steps to help reduce the RFI: 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).
