LIGHT CONTROL CONNECTIONS
The power inputs for the light controls are separate from the power input for siren. Also the power
inputs for the lever switch and six auxiliary control switches are separate. This helps prevent a
fault in one main circuit from affecting another main circuit.
Fuses / Breakers
Each light control output is fused and should be limited to 20 Amps. Properly rated circuit break-
ers should be connected between the power source and light control power inputs. Failure to
install proper circuit breakers or fuses can result in damage to the unit and/or vehicle.
