Bosch Appliances 4000 Setup And Adjustment, Amplifier Connections, Terminal Block Connections

Amplifier Connections

Siren Amplifier Connector - Refer to the Wiring Diagram in Figure 5 (page 10) for detailed information about the amplifier connections. As a standard feature, the 4000 Series of Siren are equipped with a combination plug-in terminal block/connector. To terminate the wires, strip approximately 1/4" of insulation from the end of each wire and insert it in the appropriate hole in the terminal block. Tighten the setscrew and proceed to the next connection.

Should you ever have to remove the unit, loosen the security screws and pull the terminal block straight out. It will unplug from the siren, leaving the wiring in place.

Terminal Block Connections

-V- Connect to the negative terminal of the battery. This supplies ground (earth) to the siren. Use #14 gaugewire.

+V - Connect to a positive +12 volt DC source (+24 volts for Models 4024 and 4025). It is recommended that the user protect this wire with a 10 Amp fuse or circuit breaker located at the power source (5 Amp fuse for Models 4024 and 4025). Use #14 gauge wire.

NUIT - Connect to a switch which will supply ground (earth) when ON. Use #14-16 gauge wire.

ACTIVEZ - Connect to a switch will supply ground (earth) when ON. Use #14-16 gauge wire.

HP1 - Speaker - Connect to the wire from 100W ( 11 ohm ) speaker terminal 1.

HP2 - Connect to the wire from one 100W ( 11 ohm ) speaker terminal 2.

SETUP AND ADJUSTMENT

P.A. Volume Adjustment - Public Address volume is set by the sliding volume control located on the front of the microphone. Set this control to give the desired PA Volume level. The user may adjust this control at any time during use.

Tone Selection - Referring to Figure 2 and Figure 3 and the Siren Tone Chart, Figure 4, set the 16 position rotary switch SW1 (located inside the siren) to the number which corresponds to the desired tone. Unless otherwise specified at the time of order, the default setting is 0 (Police).

WARNING!

All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of sufficient strength to withstand the forces applied to the device. Ease of operation and convenience to the operator should be the prime consideration when mounting the siren and controls. Adjust the mounting angle to allow maximum operator visibility. Do not mount the Control Head Module in a location that will obstruct the drivers view. Mount the microphone clip in a convenient location to allow the operator easy access. Devices should be mounted only in locations that conform to their SAE identification code as described in SAE Standard J1849. For example, electronics designed for interior mounting should not be placed underhood, etc.

Controls should be placed within convenient reach* of the driver or if intended for two person operation the driver and/or passenger. In some vehicles, multiple control switches and/or using methods such as “horn ring transfer” which utilizes the vehicle horn switch to toggle between siren tones may be necessary for convenient operation from two positions.
