Yup. For some reason, those detectors never detected a weapon except in that specific episode. Or at least Odo was never shown interfering when various people walked around with either Starfleet, Bajoran or Cardassian weapons drawn. And when he did interfere, such as with the Duras sisters in "Past Prologue", alarms were not indicated to be the reason he did.
And there never was a detector to indicate that a weapon was firing, unlike the starship-board ones from ST6:TUC (although even those only seemed to pick up unauthorized firings and did not react to authorized ones in any of the movies or the TOS or TAS episodes).
