EVL4 Reporting erroneous zone battery faults?

[john@harleydiver.com]

Howdy! So far so good, enjoying the functionality and features. Just yesterday I started getting these events:
Zone 50 Low Battery - Partition 1
Zone 51 Low Battery - Partition 1
Zone 49 Low Battery - Partition 1

As far as what is reported by EVL4 board directly, I have only 16 possible zones but I only have devices on 8; safewatch manual states max is 48. So wondering what are these low battery events?
