http://www.usfa.fema.gov/statistics/reports/residential_stru...When owners of commercial buildings disable life safety features, it is not uncommon for the Fire Marshal to require a fire watch (trained personnel on site walking around 24 hours a day) until the system is operating correctly.A residential smoke alarm system without a battery as backup power source is not operating correctly[1]. A smoke alarm in or near the kitchen is incorrectly placed if it is producing frequent false alarms[2].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.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.Over-riding their fucking primary purpose for the fucking sake of fucking occupant convenience  violates the fucking basic  principles of fucking life safety.This isn't disruption, it's fucking stupidity.[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. The battery is for backup.[2]Though the kitchen is the most common location for a fire in dwellings, kitchen fires are among the least likely to be fatal because cooking usually is attended and occurs during waking hours. Many building codes also require a fire extinguisher to be located in the kitchen for new construction.
