alarme

Alarme is a device or system designed to warn people and authorities of danger or abnormal conditions by producing audible, visual, or digital alerts. It is used across security, fire safety, environmental monitoring, and personal safety applications.

Common categories include security alarms (detecting unauthorized entry via sensors such as motion detectors and door/window contacts or video analytics), fire alarms (smoke and heat detectors), gas or chemical leak alarms, and medical or personal safety alarms. Modern systems often combine several functions and may send alerts to occupants, a monitoring center, or mobile devices.

Typical components include sensors that detect events; a control unit or panel that processes signals; an alerting device (sirens, bells, strobes) or a notification mechanism (text messages, push notifications); and a power supply with a backup. Many systems are connected via wired or wireless networks and may include integration with professional monitoring services and emergency responders.

Operation involves detecting a condition, initiating an alarm, and communicating with users or responders. Some systems include verification steps or tamper detection to minimize false alarms. Reliability, maintenance, and adherence to local codes are essential in both installation and use.

Regulation and standards vary by country. In many regions, standards cover performance, installation, testing, and monitoring. The term alarme also appears in several languages to refer to alert systems in daily life, including alarm clocks and other time- or event-triggered devices.
