A smoke alarm in or near the kitchen is incorrectly placed if it is producing frequent false alarms[2].<p>In the time it takes to download and install a smartphone app, one can probably replace all their smoke detector batteries - NFPA recommends changing them twice a year when clocks get reset for daylight savings time.<p>These are first and foremost alarms not detectors because there is no other annunciator device. Using the device in the way the manufacturer is suggesting - i.e disabling portions of it's alarm system - is how people die in dwellings.<p>Over-riding their fucking primary purpose for the fucking sake of fucking occupant convenience  violates the fucking basic  principles of fucking life safety.<p>This isn't disruption, it's fucking stupidity.<p>[1]Outside of retrofit applications, smoke alarms are required by the National Electrical Code [NFPA 70] to be hardwired and when located in a room used for sleeping on an arc-fault protected circuit.
