Do alarm wires need connectors, or bushings, where thy enter boxes?
This box, btw, is exactly as I found it; I was on-site to move a light, and had nothing to do with the alarm service. The cover was just as you see it.

Are you sure that is alarm wiring? I don't think I have ever seen thhn used for alarm systems, normally some multi conductor cable. I am pretty sure you need to have mechanical protection whenever any cable enters a splice box, at a minimum it is good workmanship.

On the strut to the side, you can see the box cover, which is labled "fire alarm."
While you can't see it in the pic, every panel for this building is less than eight feet away- and this mess doesn't go there.

The way that's wired certainly doesn't look like "good practice" to me.

Makes you wonder sometimes IF a fire has ever started, or could start from a malfunction in a fire alarm..

Nope, not enough energy.
And one way or the otherv it would end up in an Alarm condition.

I'd put a bushing on just to keep the wires from getting too close to a grounded metal box. THHN wire is often used in FA applications in the Golden state,CA, and sometimes a a nick in the jacket will lead to ground faults,very frustrating to chase down.
preevnt the problem before it becomes one.
