Totally unacceptable. We purchased units that ARE capable of/have UL listing, so a workaround that voids this makes it a different unit. I was ready to update to latest everything this coming weekend as I update the M1XEP to allow it to work with Windows 10. Thankfully I saw this. Suppose I must still update the M1XEP (the dinosaur of my system), but am nervous about that.
It's a moot point anyways and you're placing too much value on the system option/radio box and what it really means and does.
The panel hardware and firmware (assuming you ARE using the listed FW) are UL listed for their purpose, however in the world of UL, burglar alarms and the like, unless you have a UL certificated system, the UL listing and installation are void. Keep in mind, you would need to follow ALL the UL standards for the programming options (bell times, response times, etc.) and don't use a speaker on the M1 (not UL listed for that) and follow all the UL maximum allowances for the aux power calcs and battery standby, not to mention down to which knockouts, enclosures and tampers are installed on the enclosure with supervision on the siren(s), you're not going to be close to UL. All UL really does in the way of an alarm installation, besides verify 100% coverage (based on the UL extent shown) is provide conservative system design values. Once the installer varied from ANY of those considerations, UL doesn't matter anymore.
All the value/option does in this case is provide jam reporting to the CS. It does NOT change the functionality of the system and it's wireless operation. RF jam is usually a log event only on the templating portion of monitoring with a courtesy notification and NOT an alarm.
In my world as a pro, the UL listing also means nothing, as the installation is not certificated, however it is prudent to use the last LISTED firmware for any panel as a strict matter of CYA.
