Duct Smoke Detector wish list

[Eyeap]

Okay, Lets say that hypothetically I am designing a new duct mounted smoke detector. What features would you guys want to see in it?

These most commonly use a pitot tube, with a total pressure side (moving airstream drives into holes facing the airstream) and a static pressure port. The detector is mounted in a chamber outside the duct. Air flows into one side of the chamber from the total pressure side, through the sealed chamber past the detector, and back into the duct through the static pressure port. Usually should be in an airstream moving faster than about 400 feet per minute.

for an example.
