All The new buildings in USA requires 10 years non-replaceable smoke alarm?
It depends on the type of building. Smoke alarms are typically installed in dwelling units. In terms of power source, there are two types: (1) battery-only smoke alarms and (2) smoke alarms powered by line-voltage plus battery backup. Battery-only smoke alarms are generally found in older homes. Line-voltage (AC) smoke alarms are installed in new construction or renovations.
Many jurisdictions now require that smoke alarms powered by battery-only must be replaced with the 10-year sealed-battery smoke alarm when the smoke alarm needs to be replaced. For example, if a homeowner installed new battery-only smoke alarms (that use 9-volt replaceable batteries) throughout her home in January of 2016, by January of 2026 she will need to replace the smoke alarms with the smoke alarms that have the 10-year non-replaceable battery.
Any newly constructed dwelling units require hardwired, line-voltage interconnected smoke alarms at a minimum.
Every jurisdiction is different. Here's a snapshot of the smoke alarm law as it applies to Maryland.
For code enforcement purposes in the USA, building safety codes such as NFPA 101, Life Safety Code; NFPA 1, Fire Code; the International Building Code (IBC); and the International Fire Code (IFC) will tell you when to install a single or multiple-station alarm responsive to smoke (smoke alarms) in existing buildings and new construction. References to NFPA 72, National Fire Alarm and Signaling Code by the building safety codes should tell you how to install them.
