Weird fire alarm at Home Depot

I was at Home Depot and I heard the System Sensor Spectralert ceiling mount horn/strobes beeping. Everyone just kept shopping and I chose to evacuate. When I got to the door. It was blocked. There was a puddle of water. Right above the door was the riser for the sprinkler.

I had thought you were gonna tell us about some rare NA you saw at a Home Depot when I saw the title.

oh, sorry! 8)

So did the alarms go off because the sprinklers were leaking?

I don’t know
