What is the maximum load that should be placed on an alarm system's resources?

Explanation:
A safety margin is built into how much load you place on an alarm system’s resources. You don’t run the system at its full limit; you plan for about 20% spare capacity so it can handle spikes, multiple tasks, or a fault condition without slowing down or failing. Why 80% is the best choice: keeping the load at 80% of the maximum rating gives enough headroom for peak activity, such as simultaneous sensor polling, event logging, and communicating alerts to a central station. It also accounts for aging, ambient conditions, and any unexpected extra tasks the panel may need to perform during an alarm. Pushing closer to 100% leaves no margin for spikes or faults, and 90% is still quite tight. Using only 60% would underutilize capacity and isn’t necessary. So 80% strikes the right balance between efficient use and reliable operation.
