Alarms, sirens, and buzzers are all used to alert people of danger or warning. Whether it’s signaling a smoke alarm or a security breach, these devices provide an essential function in homes, businesses, and even in medical facilities. In a commercial setting, a loud siren can help ward off possible break-ins and deter shoplifters.
