Really cool! Gotta love seeing the TrueAlert ES in action. Don't see a whole lot of ES TrueAlerts out there nor do I see that many QuickAlerts (The older version of the TrueAlert).
I would never T-tap. In a high-rise building it becomes a nightmare for troubleshooting. Some panels have mapping, and the programmer can see the T-taps with the addresses of each device, but most don't share the location to the installer.
Depends on the type of system. Usually mapped systems can not be T Tapped or if they are they can only be T Tapped in certain areas of the system. Honeywell systems have no issue with T Tapping
