Help with a rule citation?

[CoachCER]

We had a situation in the semis of my 7th-8th grade rec league today and it is one of times when I am certain of the rule, but I can't find my rulebook to verify the ruling.

Team A is inbounding on the sideline with 3 seconds to go, down by 3 after a traveling violation on Team B.
The coach of Team A requests and is granted a time out.
After the time out, Team A lines up to inbound the ball, sees the alignment of the defense, and requests another time out.

At this point, the coach of Team B begins to have kittens, insisting that time outs can never be called back to back, and that Team A should receive a technical.

The ruling from the official who started to grant the time out request was that time outs can not be called back to back on a deadball, and that he wasn't granting the request. The ball was then put into play by Team A.

Now my understanding is that the second time out request by Team A was legal, and could be granted.

I discussed this with both officials after the game, and one believed the request was legal, while the one who denied the request (a solid guy, does some varsity ball) decided that maybe he braincramped and did deny a legal request for a time out. I will say this was at the end of a long day for both refs, and I think we were all fuzzy brained at the end.

If this is the case, could someone provide me the NFHS citation either way? I know I have made the same request as a coach without an issue, and I just want to double check.
