It makes more sense for the english message to go first then the Spanish because more people understand english then spainsh and in a real emergency, seconrs count, not that it would make a huge difference, this is the way its setup in my middle school, its a 4100es voice evac system, it does an english message which is the 4100es low rise message then the 4100es spanish message which is a high rise message so it does not match. Bilingual systems are kinda cool and rare to find here in the United states, but it seems to be poorly implemented in most cases.
It’s common down here in South Texas. My old high school auditorium uses voice evac and it played a female voice speaking Spanish then English. It was pretty neat to hear.
I was lucky enough to witness a fire alarm at Orlando Airport. They use Edwards G4 LED Strobes marked “ALERT” tied to the buildings every day speakers that play three whoop tones and a bilingual English and Spanish message. As you said, it’s rare to see bilingual systems in the United Statesbut it’s even rarer to see the messages played by Edwards G4 LED alarms.
It is a Evax 100 with Gentex speakers taped at about 2 watts each. A little more money for a system that people can hear and understand but I’m proud of it.
