Let me weigh in here. I'm also a Newton Co. fire chief and while it doesn't really matter to me if someone has my tones, I also don't see what purpose having that information would serve to anyone not involved in our county's emergency services.
Also understand, just a few months ago, we had a (now former) member of one of our fire departments who, along with an accomplice, radio in a false structure fire using a fake number from a neighboring department. This "structure fire" was in the jurisdiction in which the EMA director is fire chief. Not only was my department called to assist, but my brand new command vehicle was damaged enroute when a deer ran into the side of it just north of town...and yours truly was driving. A few days later, this firefighter and his buddy tied up the dispatch repeater with some of the most filthy language I've ever heard, calling the dispatchers names and reporting a non existent PI accident. With the use of one of my handheld scanners programmed to the repeater input frequency, he was able to be tracked down and his world came crashing down around him. I still suspect this firefighter of setting fires as far back as three years ago when I saw him in the area of a fire we were at with his scanner in hand. Two more fires were set in that same area while we were still at the first one.
Its easy to be quick to judge our EMA director for not giving out this information, and giving out these tones could be harmless, but after what we've been through this winter, he probably doesn't feel like taking any chances, and I totally understand his reasoning. I'm not sure why this would be 'public information'. Public information refers to public documents used in the course of conducting the public's business. It's intended to give the public the opportunity to see the transactions of their government officials and ensure that the public is not being harmed. Pager tones have no correlation whatsoever in ensuring transparency in government decisions and policies.
Maybe if I knew who the OP was and why he or she wanted this information I would understand better why the information was needed. If he's a member of a department and wants his scanner to activate on his department's tones, I would be happy to supply him with that information. But if this information is publicized for everyone to know, imagine the havoc it could create in the hands of someone who wanted to set off fire pagers or tornado sirens maliciously. Hopefully all of you on this board are civic minded enough and have enough common sense to understand hesitancy on the part of our EMA director...and me for that matter.
