- Alarm — A predefined acoustic, visual, or electronic signal emitted by a specialized device to warn of an imminent danger, an unauthorized intrusion, or a major emergency; by extension, a state of alert, profound anxiety, fear, or collective agitation caused among the population by the emergence of a threat. This structural mechanism includes both automated warning systems (fire, burglar alarms) and the psychological or operational reaction of immediate mobilization of intervention resources.
