What is An external siren?

An external alarm siren is designed to produce loud sounds and flashing lights to warn others of an intrusion or emergency at a property. It is typically connected to an alarm system that activates it upon detection of breaches; its tones and patterns indicate both type and level of threat. It serves as a deterrent against intruders and assists in locating the source of the alarm during emergencies.
