You can thank Motorola for that. Their consoles don't do the post-QCII warble that the old Zetron's did. And the agencies want/need that warble. So the DTMF sequence is what we came up with. Not happy with it, the technicians don't like it, but it is what it is. Would like to speed it up, but since Halstead's sirens use DTMF at a set speed, and Newton Fire needs 3 seconds to allow for their station bells to go off before voice can start, they have to be sent as slow as they are.
