Multiple item detection on belt

Hello,

I have a question about detecting items on a belt.
Of course it is easy with a wire connected to a decider combinator make something like:
"If item A is on belt, send signal xyz"

If I want a logic like
"If item A OR item B is on belt, send signal xyz"
I simply use two decider combinator. Still fine.

But I'm up to a point where I need something like
"If item A OR item B OR item C ... is on belt, send signal xyz"
Current installations require up to 25 different items in this condition. I don't want to have 25 decider combinator (per belt) to detect that. Has anyone a suggestion how to evoke an action if one of 25 possible items is on the belt?

Anything > 1000, send xyz.

Constant combinator setting each desired item to 1000.
