Imp. Thermal Converter's effect should say "energy", not "energ":

And also, I'm not sure if this is considered a bug or not, but when I saw a garrison access in a room with a sentry hidden at the corner (I was carrying sensor array), I positioned myself at the doorway and fired 2 shots to disable the garrison, believing that the sentry will come after me. Surprisingly, it didn't react at all. (I guess the 24-hour shift is a little to tiring?)

Typo was reported a couple weeks ago on the chat and fixed, thanks. (Changed that description a little too quickly last release when updating!)
And that's normal behavior for a Sentry. Garrisons behavior has never included alerting nearby robots, nor do bots respond to pure sound or projectiles.
