Old Video - ASDA Lowestoft Fire Alarm Testing

I found this video on my old phone (some photos had failed to transfer over to my iPhone, and I found this when sorting that out) and I wasn’t sure if I should upload it, but everyone voted for it, so here it is. I’m not a fire alarm enthusiast so I have absolutely no idea what system this is. The video quality isn’t great, however this was recorded on my old phone back in 2021. Unfortunately, I’ve never been lucky enough to be in a place when it’s been evacuated other than my school, but I’m sure it’ll happen one day, and I’ll make sure to get a decent video of it. I’m sure you know that the dryers here are Xinda GSQ87s as I’ve filmed them all before, however the one in the baby room has Biodrier branding.
