I see those in big hotels with an EST Genesis white speaker on the same wall.
I find it interesting that hotel rooms also typically have one of those clapped First Alert Smoke/CO detectors (Yes that one that can say “Detector error in [room name] please see manual”) even though they aren’t wired up to the fire alarm system (As far as I know unless if you can get a househole smoke detector up to a panel) however this hotel in perticular (Hyatt Regency Seattle, the one that hosts Anthro Northwest) doesn’t have any pu!l stations.
