🔍 Key Concepts
• Typical color codes on fire detection panels (normal, alarm, trouble, backup)
• How power status and system faults are usually shown vs. actual fire/smoke alarms
• Difference between main power and emergency/backup power indicators on control units
💭 Think About
• Ask yourself: which condition (normal, trouble, alarm, or backup) would designers want to stand out the MOST and be unmistakable at a glance?
• Think about what colors are commonly used for danger or alarm versus information or status on most safety panels.
• Consider how a mariner could quickly tell the system is running on emergency power during a blackout—what kind of color would be clear but not easily confused with an alarm?
✅ Before You Answer
• Match each option to the most commonly associated color (e.g., red, yellow/amber, green, blue).
• Be sure the color used for actual fire/smoke is the one that would draw immediate attention and likely trigger an emergency response.
• Verify which status (normal power, trouble, alarm, backup) would be most reasonable to assign to a blue indicator instead of red, green, or amber.
