Short title	Two detection and notification paths sharing one power and control dependency.
Image title	Two redundant paths, A and B, each starting from a detector, both pass through one shared dependency (power, control and communication) before reaching the occupants. The shared dependency is marked as a single point of failure, with a failure indication connected to it. A note says the backup helps only if the shared dependency is addressed.
