I was at a museum and I saw this device: a Wheelock RSS with both wall and ceiling mount lettering. This is the only such device I have ever seen.
Oh, such a rare device to see in buildings. A Wheelock RSS with a ceiling and a wall plate. Did you find a red one that?
No, I did not see a red version of that device. In case anyone is interested, the rest of the system is Wheelock RSS’s and AS’s (all ceiling mount), NOTIFIER NBG-12LX pull stations, I think a NOTIFIER annunciator, and some smoke or heat detectors that I can’t identify.
