I do apologize for the few month bump, Just last night I found something very interesting about Riyadh's system. I've already posted about this on the subreddit, But I thought I'd share it here for people who already don't know about this. So almost a year ago a video was uploaded to YouTube featuring a archive of a News Report in 1990 about what to do when a certain signal is sounded from the sirens around the city, What's interesting about this though, Is that during when they play a audio clip of each siren signal they also show a Cyclone 120 roof-mounted on a high concrete building for what I assume is reference. Unfortunately the Cyclone itself isn't sounding off in which a audio that is also the audio used for the TV alert shown to warn civilians about oncoming SCUDS, was overlaid on the siren footage, but whatever. Here's the link to the video:

The Cyclone 120 itself can be both seen at 0:46 and 1:24 in the video.
I'm not sure if the video shows the same location that was seen in the photo that I posted a few posts earlier, However someone from the subreddit on my post says the photo was taken from a different location (in which the person who had taken that photo, had the siren installed on top of their house roof by the government), But its still cool to discover stuff like this.
