PIR Motion Sensors in Class 1 Division 1 Spaces - Are they Considered Simple Apparatus?

I am working on a space that is Classified as Class I Division I.  We need to install an Intrusion Detection System in the space and as part of a "normal" Intrusion Detection System, PIR Motion Sensors are used to detect unauthorized occupants.


The Intrinsically Safe/Explosion Proof Motion Detectors that I have seen appear to be very limited with their range as opposed to the sensor we typically use (PDF attached).


My question is, is the attached PIR Motion Detector considered a "Simple Apparatus" thus not needing to be specifically labeled as IS or Explosion-proof? 

Any guidance would be greatly appreciated.
