I am a rental property owner and have a bunch of 3 bedroom apartments, To meet the building code I have interconnected hard wired smoke alarms in every bedroom and one in the common area. The problem is that they go off ALL the time, and since the units are small there are 4-5 alarms blaring in 900sf. Is there a way LEGALLY to make them LESS sensitive but still get the job done? What happens is that my tenants just remove the detectors and then nobody is safe if there is a real fire.

But it is a real nuisance to have them go off just warming up the oven. I use Kidde detectors. Please Help…….

Which is better ionization or photoelectric??
