Morphology
The meaning is directly and compositionally derived from 'alarm' (a signaling device) + 'system' (a collection of interacting components); a B1 learner who knows both words can infer a set of devices for signaling danger. This noun–noun compound follows a common, cross-linguistic pattern of composition and is therefore immediately interpretable without prior exposure.
Etymology
Alarm system comes from old times when a loud bell or shout — an alarm — was used to warn people, and when several alarms were joined as a system they could warn a whole house or town, so today the phrase means 'a set of devices that warns of danger'.
