With 2-way radio systems, alarm signals can be verified and acknowledged back at the Supervising Station. With conventional, 1-way radio systems the alarm signals can be verified (1-way), but not acknowledged, hence, there is no way to determine if the alarm signal was received or if anyone was listening at the Supervising Station. This makes 2-way radio systems more reliable.
