Tenants always remove batteries from smoke detectors when they go off whilst cooking/frying. And they clip the hard wired ones as well.
I have to say in all seriousness, as the long time owner of a very high end South Philadlephia row home, anytime our several generations of ovens get above 325 degrees, unless the vent out fan and the back door with a fan are on full blast, the smoke detectors go off and the kids grab brooms to bash them until they shut off. So much that all our neighbors know to disregard them - it’s one of the first things we tell new neighbors.
We’ve had several contractors in who’ve told us that is the city code, so, although I’m skeptical of exactly what was going on in that home, there are exacerbating factors in the realm of possibility.
