Outdoor sirens are oftentimes overlooked in favour of silent alarm systems. People often forget that the point of an alarm is to make a big fuss out of an emergency. And there’s probably no better way to do that than with loud noises and illuminating flashes. A common place where sirens can be seen are emergency service vehicles such as fire trucks, police cars and ambulances. But there are many other places where the use of a siren alarm is more than needed; it can save many lives in case of a natural catastrophe or a hazard at a workplace. Let’s look at some applications of a siren alarm.
Fire Station Sirens
These are crucial to alert traffic and pedestrians that fire trucks are being mobilized. A siren alarm of this kind contains an integrated light system in addition to the loud noise it produces in order to increase awareness and make firefighting equipment deployment more efficient and safe.
Civil Defense Sirens
These are also known as air-raid or tornado sirens, used to warn the population of an approaching danger. At first they were used to warn about air raids in World War II, but later were adapted to warn about nuclear attacks and destructive weather patterns like tornadoes.
There are many types of siren alarms and each one of them has it’s specific purpose and excels in one way or another. Let’s take a look at some models and discuss their capabilities and specifications.
