Intruder Alarm Functionality
The SPC system can accommodate 2 distinct modes of intruder alarm operation,
Commercial Mode or Domestic Mode, both of which support multiple areas.
Each area in turn can support 4 different alarm modes. Commercial Mode presents
more programmable alarm types than Domestic Mode. The default zone name and
type settings for each mode is listed in Appendix H: Domestic and Commercial
Mode Default Settings.

Commercial Mode is suitable for business installations with multiple areas and a
large number of alarm zones. Each area defined on the system supports the alarm
