All residential or commercial intrusion/burglary alarms that have central monitoring must have a central monitoring verification call made to the premises generating the alarm signal, prior to alarm monitor personnel contacting a law enforcement agency for alarm dispatch. The central monitoring station must employ call-verification methods for the premises generating the alarm signal if the first call is not answered. However, if the intrusion/burglary alarms have properly operating visual or auditory sensors that enable the monitoring personnel to verify the alarm signal, verification calling is not required.
