I like temporal on newer alarms such as the commander 3 or the spectralert classic. But on older mechanical horns such as the 4093 or 2903-9806 I like march time. But I have lived in buildings build on or after 1996 and I have been exposed to temporal more than others. My new high school was build In N he 70’s and does temporal (but you can tell where the 2903’s were they removed the light left the. Box and where the horn was slapped on a mt pre Ada strobe but the middle school nearby does 60bpm march time and they have old mechanical horns. But meh my hs has MT3’s Non Ada mt’s and some true alerts, 4903’s and commander 3’s. Quite a weird one.
