Morphology
The meaning is directly and transparently composed from 'factory' (a place of production) + 'whistle' (a device that makes a sharp tone): it refers to the whistle used at a factory to signal work times. This simple noun–noun/possessive composition is common cross-linguistically and follows basic English compounding, so a B1 learner who knows both constituents will readily infer the meaning.
Etymology
Factory whistle comes from the loud whistle blown at a factory so workers across the town could hear when it was time to 'start' or 'stop' work. So today it means a whistle that signals the beginning or end of a work period.
