SpectrAlert Classic horn strobe sound effect but on temp 3 3k interrupted to like a old smoke alarm

This is a sound effect of the System Sensor SpectrAlert Classic horn strobe on it's temp 3 3k setting to sound like an old smoke alarm prior to where smoke alarms would make a temporal 3 sound pattern instead of a 180 millisecond on 20 second millisecond off sound pattern. However, with a System Sensor SpectrAlert Classic horn strobe, they make the same sound when it's on it's 3k interrupted setting but on the temp 3 version of it it becomes the temp 3 sound of an old smoke alarm and I also uploaded this because that's the fire alarm in my school but all of them are on temp 3 horn and I got to pull the fire alarm for the fire drill at school today at 10:45 AM EDT (5th time)
