What is the purpose of a siren in an alarm system?

The primary purpose of a siren in an alarm system is to emit a loud sound to deter intruders and alert occupants. When the alarm is triggered, the siren acts as a deterrent by signaling that an unauthorized entry or security breach has occurred. This loud noise not only alarms the potential intruder, making them more likely to flee the scene, but it also alerts nearby occupants and neighbors to the situation, prompting a quick response.

In the context of a home or business, having an audible siren can enhance security by ensuring that anyone in the vicinity is aware of the alarm activation, thereby increasing the chances of intervention before any theft or vandalism can take place. This proactive alert system serves a dual purpose: protecting the property and enhancing the safety of those within it.

For instance, notifying a monitoring station of a malfunction is a critical aspect of system reliability but does not involve the immediate reaction aspect of the siren.
