How to tell when a pawn is no longer sensed (pawnsensing)

In my case I have a radius where the enemy can see the player, 10,000.00 units for example, every 100 milliseconds I verify if the player is in that radius, if hes not in the radius I’ll set variable isPawnSensed to false. Because in my case is hard to the enemy see the player, if I base my logic on the PawnSensing Component player again, but not a radius, I wont have too much control over it and I think its not going to feel good to my game.
