An arrangement for locking arming conditions to prevent unintentional arming of SAI-units of ammunition units when the ammunition unit is subjected to external threats. A ring shaped shape memory alloy is provided in cooperation with a recess in a plunger arranged in connection to the SAI-unit and a fixed recess to prevent the plunger from axial movement when subjected to heating by changing the shape of the essentially ring shaped shape memory alloy to lock the plunger relative to the fixed recess.
