providing a signal to the horn ring auxiliary wire when the function switch is in the Hands Free (HF) position. A Park Kill option is provided for connection to a door switch, etc. to disable the siren when exiting the vehicle. The PA volume control is provided on the front panel of the control head, while the Radio volume is on the amplifier box. The front panel is backlighted with LED’s for night visibility.
INSTALLER-SELECTABLE OPTIONS The SS730 has several options that can be selected during installation. Jumpers on the back of the control head, as well as on the printed circuit board inside the amplifier case, allow the installer to select these various options. These options should be set before installation of the unit.
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” option jumper from the “Pos. Switching” pins to the “Neg. Switching” pins in the amplifier unit. (See Amplifier diagram below).
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. The wiring diagram on page 10 shows two connection examples. NOTE: Permanent disconnection of the vehicle horn is NOT recommended. The siren is factory shipped with the auxiliary input option defaulted as the Horn function.
Horn Ring Transfer The installer may opt to have the sirens electronic air horn replace the vehicle horn. This can be done by adding a single pole, double throw (SPDT) switch. Two Horn Ring Transfer wiring diagrams are shown below. MOUNTING SAFETY PRECAUTIONS For the safety of the installer, vehicle operator, passengers and the community please observe the following safety precautions. Failure to follow all safety precautions and instructions may result in property damage, injury or death.
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. Be sure to choose a location that has at least two inches of depth to accommodate the control head and cables.
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. You should make all electrical connections to the power connector before installing the connector on the unit.
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. • Make sure all connections are tight. • Route the wiring to prevent wear, overheating and/or interference with air bag deployment.

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. POWER In order for the siren to function, the power switch must be in the ON position.
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 . WAIL - A normal rise-fall tone used on highways and areas with low traffic or constant traffic flow. Please note that for the SS741MG-TEC the 7 -position knob functions are reversed.
MAN 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. Pressing the button once changes to the next faster tone.
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. Adjust the siren’s rotary selector switch into the RADIO position. Insert a small, flat blade screwdriver into the RADIO volume adjustment port. Turn clockwise direction to increase the sound level.
TROUBLESHOOTING Symptom No power Possible Cause Check Power switch not turned on Connector loose Amplifier 20A fuse blown Does back-lighting come on? Do you hear a “pop” when turned on? 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? No siren High voltage protection The input voltage must be less than 16 volts.
If you are experiencing an unusually high amount of RFI, you may perform the following steps to help reduce the RFI: 1. 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). 2. Keep the siren control head and the police radio as far away from one another as is practical. 3.
