Abstract
A combined smoke detector and cooling control system for a mobile platform is operable to control multiple electronic units. A smoke detector is connected to the electronic unit and operates to identify a smoke event. A cooling system is connected to the electronic unit. A fan in the cooling system includes a switch which indicates if a cooling system fault occurs. A plurality of relays connect to the electronic unit, the smoke detector and the cooling system. If a cooling system fault occurs, a first relay immediately de-energizes the cooling system. After a fixed period of smoke persistence during a smoke event, a second relay de-energizes the cooling system.
