Interesting situation

[Refsmitty]

I am a local HS referee. My neighbor is the clock keeper for the local school. Our school held a regional final which was attended by 2500 or so people. Loud - I watched the game - could hardly hear the officials whistle.

Sit - 1 minute or so to go - coach farthest away from the end where the officials were - trying to call time out during dead ball - could not be heard and could not get refs attention. Clock keeper gave a quick buzz of the horn... he wonders if he did the right thing... I have never read anything about this in the rules or case book... but I doubt if it is the right thing...

Help please....
