New attached garages must have heat detection (interconnected to dwelling alarms)

Description

Heat detection rated for ambient outdoor temperatures must be installed in attached or built-in garages serving new or existing dwellings, in a central location per the manufacturer's instructions, and interconnected with at least one smoke alarm in the dwelling (so that garage heat triggers the dwelling alarm). Detached garages connected to a dwelling by new construction also count. Exempt: dwellings without commercial power.

Why this exists

Garage fires are a common ignition path into the dwelling. NY's heat-detector rule (smoke detectors in a garage would false-alarm constantly from cars + dust) gives early warning while remaining reliable. Architects should specify the garage detector and its interconnect path during electrical layout.
