Fire Detection
Multi-Sensor Smoke + Heat + Flame Detection
Multi-sensor fire detection (smoke, heat, UV/IR flame, gas) per ISS heritage with rapid alert and isolation triggers.
Purpose
Multi-sensor fire detection (smoke, heat, UV/IR flame, gas) per ISS heritage with rapid alert and isolation triggers.
Context
Child of L2-HAB-FIRE within the Lunar Ark system
Principles
- ▸Optical smoke detectors per habitat zone
- ▸Thermal sensors for heat rise
- ▸UV/IR flame sensors for fast detection
- ▸CO/HCN gas sensors detect combustion products
- ▸Multi-sensor voting reduces false alarms
Typical implementations
- ▸ISS Fire Detection and Suppression heritage
- ▸NFPA 99 standards
- ▸Aerospace fire safety
Lunar considerations
- ▸Sealed cabin atmosphere flammability differs from Earth
- ▸Lunar-low-flammability material selection
- ▸Rapid response (~10 s)
