Fire Alarms at the Kinzie Hotel in Chicago, IL
Simplex QuickAlert 75CD remote strobe (This is either a Simplex 4904-9169 or 4904-9332)
Simplex QuickAlert 110CD remote strobe (This is either a Simplex 4904-9170 or 4904-9333)
This one has an Orange Triangle to indicate the 110CD!
Simplex 4904-9164 110CD Ceiling strobe (RARE!) with both wall and ceiling lettering
A Wheelock remote speaker of some sort. These were the speakers, the QuickAlerts were the strobes
I’ll admit, this was quite an interesting ADA compliant system from 1999! I’m assuming the hotel was built in 2000.
