What is it you're trying to do specifically here? Detect evil shouldn't stop you from using jump scares or anything. I mean, Paladin's are immune to fear and all, but they can still be surprised as much as the next person.
I want to avoid the Pally becoming conditioned to use DE as a crutch for determining when there is real danger and when it's just his imagination getting the best of him. One of the tools in the GM's (or writer's, movie director's, etc) arsenal for creating fear is creating uncertainty...alternating evil with red herrings to keep players off balance:
For example, here is how a couple of the Haunting of Harrowstone (HoH) events could play out:
"Ah, that must be Pevrin, delivering the supper I ordered from the Laughing Demon. I'll get it." says the Sorc.
She opens the door and is greeted by Professor Lorimor, maggots crawling from his ears and eyeballs, reaching out to throttle her with his leathery gray hands.
WITH DE PINGING: Replace the last paragraph with:"Wait, let me check something first," says the pally. He focuses on the front door for a few seconds. "Don't open it--moderately strong evil on the other side."
"I'll go out the back door, circle around to the front, and kill whatever foul creature it is that darkens our door!" Says the ranger.
Or
DM: As you get closer, you are able to make out the words of the song that the children sing as they jump rope. Several twisted tails of grisly murder...
"What foul evil has possessed these 'children'?", cries the pally. Tis not natural, even among the dour residents of this accursed town!"
The pally draws his sword and approaches the closest girl. "What manner of spell is this you sing, you heinous beast of the depths? I shall gut you where you stand!"
The ranger leaps to intervene, grabbing the pally's sword pommel, "Stay your hand, friend Pally! It's a grisly tune, to be true, but perhaps these are but simple children who are merely victims of the dire spirits that hangs over this unfortunate town!"
WITH DE PINGING: Replace the last two paragraphs with: The pally stares strangely at the girls for a few seconds. "Ah, I see. Go about your game, young ones. And remember to floss!"
Ok, these are admittedly a bit extreme, but you get the idea. Having the Pally pinging all over the place is like the the horror movie character that somehow gets the lights to stay on while the killer is loose in the neighborhood. More information = less suspense = less fear = less fun.
