This is based off a real fire alarm, the System Sensor SpectrAlert Advanced! It was made around 2006, and is system sensors newest alarm! It is also considered one of the loudest fire alarms on earth! This model does not make sound, but it very detailed and accurate to the real alarm. I have one in real life, and i was constantly looking at it while making this. This alarm IS and industrial alarm, found in commercial building, and it isnt your typical home smoke detector!

have a nice day :)
