->  Can you modify this timing to something longer? Like 250ms tone, 250ms
  space/delay?

---- Those are the exact questions I asked the fire alarm panel guy and it 
appears the answer is no once I got him through his 10 minute tirade it used to 
work on the DMS and other things he saw go wrong over his career. I also wanted 
to know if the alarm panel could manually dial a call like a pots line could 
and I never got a clear answer on that or documentation on the panel that I 
could study myself. So maybe the answer is no, maybe he never tried to do it, 
or he has no clue.

---- I get the feeling these alarm panels are quite old and based on the 
pictures I saw of a couple of them ancient. They have definitely been on the 
wall for 20 plus years along with that DMS switch sitting in our central office.
