Bosch FAH-440 — analog addressable heat detector head, selectable fixed temperature with switchable rate-of-rise.
This is the head only: it plugs into a base from the FAA-440 family, ordered separately, and ships with a dust cover. It belongs in indoor dry spaces that run hot or steamy — kitchens, boiler rooms, drying rooms — where a smoke detector would nuisance alarm. A multi-colour LED flashes green while the loop polls the head and holds steady red in alarm. Bosch positions it for general property protection and notes that it is not a life safety device.
