Morphology
The meaning 'a clock that warns or wakes someone' is directly compositional from 'alarm' (a signaling/warning device) + 'clock' (a timekeeping device); the compound simply specifies the clock's function. This noun+noun formation is a regular, cross-linguistically common pattern and would be immediately clear to a B1 learner who knows both constituents.
Etymology
Alarm clock is made from alarm (a loud warning) and clock (a tool that shows time). Long ago people used bells as 'alarms' to warn or call others, and when clocks were made to sound that warning at a set time to 'wake' someone, they were called 'alarm clocks', so the name means a clock that wakes you.
