An alarm is a warning system or signal that indicates danger, a problem, or the need for immediate attention. It can be a sound, a light, a message, or a combination of these, used in contexts such as security systems, fire protection, timekeeping, or technical monitoring. Alarms are designed to be noticeable and often urgent, prompting people to take action quickly, such as evacuating a building, checking equipment, or waking up. The term can also refer to the emotional reaction of sudden fear or concern when a potential threat or serious issue is recognized.
