Take a look for yourself. I assume that they use the Whoop tone here on the horn strobes since with the bootleg Spectralert, they didn’t use traditional tones. I guess the code here forces red strobes at least on white alarms.

When it comes to building codes, including fire alarms: Mainland China != Hong Kong

Despite that though, this is a very nice find and it is still really cool!
