Is there an industry standard with regards to how long it should take for the signal from an activated alarm sensor to reach the central monitoring station or command center, 1-2 seconds, a millisecond? This question applies more towards larger sites that may incorporate outlying perimeter sensors in addition to those installed at building entrances. I recognize that the infrastructure will have an influence on the signal (distance, processor efficiency). This question is not about how long it should take for the central station to respond to the alarm notification once received and to dispatch security.
