A wireless smoke detector that ties into the Dahua AirShield system. On smoke it sounds a loud local siren and signals the hub, so a fire event reaches you wherever you are — not just the people in the room. One button tests and silences it, the lithium cell is replaceable, and it is listed to the EN 14604 smoke-alarm standard. Supplied and fitted by Skyview.
