Facts

[@joeycaridi3030]

I can hear some Simplex Truealert speaker strobes playing a 500 Hz code 3 tone in the background when the Simplex guy gives the voice evacuation directions and I think it's because you can have speaker circuits only on the newest Simplex 4100ES playing different tones or it could be a different panel that isn't doing a slow whoop tone

This is probably a chime strobe or low frequency could also be the FACP

My school has this system

[@OctoCorn]

[@SomeDudeWithAnExitSign]
