Those are so loud and piercing; they're just like System Sensor's SpectrAlert Advance and Wheelock's AS horn/strobes. But they're still nowhere as loud as the really old fire alarm bells and horns of the past, like my public schools had.

The spectralert advance and wheelock alarms are louder than simplex true alerts I think.

Next time, you have a fire drill, we need more video of the 7002T's.
