That is true, but it is only an alarm of sorts. It does not allow for
intermittent keying last I knew. A downed cop or firefighter could key a
location such as "bedroom" or " bathroom" or whatever.

There is AVL as well, but that usually is for the mobile radios.
Kinda-sorta-maybe like APRS.

Fortunately, there are other ways to accomplish the same task, that
being to alert other firefihters to the plight of the trapped
personnel. The fire department in Buffalo, NY equips members of its
interior teams with portable radios that have a "man down" button on
them. When said button is pressed (which isn't hard to do, it happens
very often by accident) it activates an alarm on the MDTs in the rigs.
The drill then is that all other comms stop at once and a headcount is
performed. It doesn't even have to be the MDT on the rig he or she is
assigned to - any MDT in range will initiate the alarm. Other
departments probably use that technology as well, I merely am aware of
this one since I live relatively near Buffalo.
