What changed for the reader

• The source is useful because it keeps reading alarm, egress, backup, and communication details as a system tied to real field language instead of abstract test wording.
• The common exam trap is thinking emergency equipment only matters after an incident starts.
• Candidates should turn the topic into a short timed drill, then explain the rule cue before checking the answer.
