CONE OF VISION—
The detector has a 90° cone of vision (horizontal) with
the highest sensitivity lying along the central axis.
See Figure 15.
RESPONSE TIME—
32 inch methane plume: < 10 seconds.
1 foot x 1 foot n-Heptane: < 15 seconds.
(See Appendix A for details.)
SOURCE TUBE—
Contains radioactive isotope Krypton 85 (Kr
85
)
Calculated Activity: 14,800 Becquerels (0.4μCi).
Note: Not applicable to model X5200G
ENCLOSURE MATERIAL—
Copper-free aluminum (painted) or Stainless Steel (316/
CF8M Cast).

DIMENSIONS—
See Figure 16
WIRING—
Field wiring screw terminals are UL/CSA rated for up to
14 AWG wire, and are DIN/VDE rated for 2.5 mm
