Description 2.6
The SafEye is comprised of 2 main units:
 The Flash Source Unit
 The Detector Unit
Xenon 700S detects gases over an open path transmitted from the flash
source to the detector.
2.6.1 Flash Source Unit
The flash source unit emits IR radiation pulses at the rate of 2 pulses per
second. The pulse width (5–10msec) is very powerful. The front of the
source unit has a coated lens that collimates the IR beam for maximum
intensity. The coated lens blocks all the UV and visible lights from passing
through the lens, and prevents the flash pulse being visible to the eye. The
lens is heated to improve performance in ice, condensation, and snow
conditions.
There are 2 source types:
 Short and medium range : For use in Models 701S, 702S, 721S, and
722S
 Long range : For use in Models 703S and 723S
