Dispatchers / 911 Operators
Dispatchers may love The Fire Horn even more than the people receiving the calls.
The Fire Horn's interface has been tailored with dispatchers in mind. When a responder receives a text message from a dispatcher, the responder always knows where they are going, and what the nature of the call is for. This greatly reduces radio traffic, and allows dispatchers to focus on taking calls, not repeating addresses or other information.
