Seem like it would be better with cutoff switch. It seem to me if it was a problem they would all have their own battery, the smoke detector in my house runs for a year in my house on it's own battery. Since the manufacturer does not supply a cut off switch that the safety devices are hot. The owner has no chose to put in a cutoff switch ( or pull a wire off the battery) that cut off everything. How is that better?

I think it's all about litigation. If the mfg installs a disconnect switch that disables safety devices then the responsibility falls in their laps. While your point in the battery will die after a given time therefore disabling the safety devices is correct, however the responsibility now falls on the owner for not properly maintaining the battery and ensuring that it's properly charged.
