Morphology
The meaning 'an event or signal that alerts people to a potential problem' is directly and transparently derived from combining 'warning' (a message alerting to danger) with 'bell' (a signaling device). This is a straightforward compositional noun-noun combination following common cross-linguistic patterns, so a B1 learner who knows both words can readily infer the MWE's meaning.
Etymology
Warning bell is used for any early sign of trouble. Imagine a bell that rings to get people's attention before something bad happens; that's why a 'warning bell' now means an event or signal that tells you to check for a possible 'problem'.
