That would still be automatically supervised (just not monitored). The building code triggers monitoring systems (previously referred to as electrically monitored) keeping in mind that once upon a time many large system were not monitored (aka only chains on the valves, just a local bell, etc). When not monitored, it is meant to impact the frequency the system had to be inspected. It is pretty clean in NFPA 25 for Dry pipe where monitoring the low temp changed the inspection from daily to weekly and where air pressure is monitored inspection went from weekly to monthly. Pre-Action is not so clean were the temp monitoring also changes from daily to weekly but the gauges sit a weekly regardless (without really intending to be different IMHO).
We all know tight rigor is applied by the owners doing all these inspections. As a side note, the issue of inspection frequencies for gauges has a good chance of finally being updated. Look at the 25 First Draft report when it’s published.
