Operating Constraints
Installation of the Aura Fire Alarm ControlPanel must include the operating constraints of the system to maintain
continuous signal monitoring and reporting. Operating constraints are based on the current-driving capability of
the panel while maintaining external loading caused by devices and cabling.
External loading must be selected within the limits of the Aura Fire Alarm ControlPanel to provide continuous
operation. External loading is caused by individual or multiple combinations of Signaling Line Circuits,
Notification Appliance Circuits, and Initiating Devices. It is also caused by the size and length of cabling
connections. Refer to Calculations to determine the appropriate size and length of cabling.
