Fire-Lite MS-2 and MS-4 Discontinued; New Panels Coming

Well considering Edwards’ track record (read: very good) I’m trusting that they’re telling the truth about their Signature Optica-series being elaborate & as a result a lot better at distinguishing between false alarms & actual fires. What did Siemens do with their FirePrint detectors though?

I could have sworn the 2151-series is no more for whatever reason (though I know Fire-Lite & Notifier no longer sell the addressable versions of the 2151 that they used to, since their current detectors look completely different).
