SPC Intrusion Events Reference
This section describes the main intrusion events, according to the category to which they are assigned.
For step-by-step procedures about how to handle intrusion events, see Handle SPC Intrusion Events.
Life Safety
Life Safety events have maximum priority. They signal either:
- Immediate risk to human life, as in the case of duress.
- Potential risk to human life, as in the case of burglary, or signals from seismic detectors.
Such events call for immediate action by the station operators, according to predefined alarm-handling guidelines.
Danger
Danger events signal that a sabotage action is likely to have happened. For example, tampering, unlocking of a zone, or a connection going down.
Such events require station operators to act as soon as possible to prevent further risks.
Fault
Fault events signal hardware problems, such as battery faults or unreachable devices.
Exclusion
Exclusion events may occur if an area is enabled/disabled (see Arm/Disarm an SPC Area) or if a zone is turned off or excluded, for instance due to maintenance activities (see Bypass an SPC Zone).
Anomaly
Anomaly events occur when some unexpected condition, such as a configuration anomaly, prevents the system from being fully operational.
Information
Information events signal the status of the system status occurring during ordinary engineering or working activities. Some examples are: system set to Engineering mode (thus preventing commands from being executed), zones under soak test, conditions that can impede arming the intrusion system (such as a door left open), user-logging and time-setting changes out of the allowed time range.
Note that, due to the wide range of information events, the station operator should evaluate the real meaning of such events, which could involve potential security risks.
