Federal Signal VAMA AS-422 Manual De Instalación E Instrucciones De Funcionamiento página 18

Connect the power cables directly to the battery or a chassis part that will provide an effective
ground path. Protect the installation with four 15 A fuses situated as close as possible to the battery
connection, as shown in the wiring diagrams at the end of this manual.
The lights or warning lightbars are supplied with a wiring diagram. These diagrams usually include
the light control switches. In the case of this siren model, the switches will be replaced by relays situated
in the amplifier. The positive power cable to the light or lightbar would be connected directly to the
amplifier connector.
