Inputs – Intrusive and Non-Intrusive
The gas monitor can be configured using intrusive and non-
intrusive means. Both methods of configuration are accomplished through
physical inputs that are visible behind the glass panel of the gas monitor.
A set of four keys are used when intrusive programming is appropriate (i.e.,
when the enclosure can be removed and when the keys can be manually
pressed). These keys are the mode, increment (+), decrement (-), and enter
keys. Refer to Figure 2-3.
For applications that require non-intrusive manipulation, two magnetically-
activated reed switches are used to accomplish programming without
removing the cover. A magnetic wand is positioned over the appropriate
reed switch (above the glass face plate) without the wand physically
touching the reed switches. The locations of the reed switches are shown in
Figure 2-3.

Programming the gas monitor in both intrusive and non-intrusive
modes is explained in detail in Chapter 5.
