The Alarm Confirmation Technology
- Sequential Confirmation - An activation from two or more independent sensors or detectors, can determine that there is a high probability a genuine or attempted intrusion has occurred.
- Audio Confirmation - An activation confirmed by the Monitoring Centre operator who, after having listened in to the premises, has decided that there is a high probability that a genuine or attempted intrusion has occurred.
- Visual Confirmation - An activation confirmed by the Monitoring Centre operator who, having interpreted a visual image transmitted from the protected premises, has decided that there is a high probability that a genuine or attempted intrusion has occurred.
- Systems Without Confirmed Signalling - This is a single signal and may receive a police response, if its a system in Scotland that has not had police response withdrawn, or in England, Wales or Northern Ireland that has been installed prior to October 2001.
- A System With Confirmed Signalling - A line cut signal followed by a second signal will initiate police response.
