Here’s a crazy idea. You use one tone but you break it up. One long for high ground three short for… huh, that’s new. What do? Oh it says here, fire get out no

  It's quite possible you are not familiar with how sirens work. The need constant air movement and make a continuous sound as the air is moving. These are the types of sirens that make the wind up sound before it gets to full speed, and then makes the wind down sound as they slow down. Think of air raid sirens from a WWII movie you might have seen. These are not the types of alarms you might be thinking of from your days in primary school
