Technical Side  

Can VOCAL SCW 1 be built into lorries (24 V electrical system)?

YES. For lorries we offer a special version VOCAL SCW 1 24 V. Installation goes the same way as in a diesel driven car.

For older lorries without EDC use a solenoid valve suitable for trucks.
General note re. insurance requirements (for Germany):

Not all insurance companies require for lorries generally blocking of 3 functions (threefold antitheft device). At that rate VOCAL SCW 1 would be sufficient all the time, even without additional solenoid valve.
