The critical systems of your facility, such as the HVAC, electrical, plumbing, smoke detector, telephone, computer, and sprinkler systems.
With the Space domain's Emergency Preparedness application, you can map dependencies between facility systems, such as noting that the HVAC system is dependent on the electrical system. Thus, if the electrical system is unavailable during an emergency, the HVAC system will likewise be unavailable.
You can graphically document each facility system's zones – that is, you can use a zone to specify a particular area on a given floor that is covered by the electrical system.
