Commercial airplane costs can exceed $200 million, while military aircraft can cost exponentially more. High-performance systems that detect heat or flames and actuate fire suppression systems are essential to safeguard assets, hangar structures and human life.

Solutions must address a hangar’s unique challenges:

– Large detection expanse that contains sizable obstacles
– Large hangar doors that create variable conditions
– Radio-frequency interference (RFI) that can create false alarms

Beyond equipment choices, a superior installation takes expertise with standards, codes and optimal placement.



One size does not fit all. A hangar’s unique characteristics require special planning, design and implementation considerations:

1. Placing flame detectors
2. Rejecting of false alarms
3. Building in redundancy
4. Speeding detection and decision making
5. Integrating fire and gas detection and suppression

Det-Tronics provides the site analysis, technologies and controls required. Guidelines on protecting your aircraft hangars with optical flame detectors can be found in FM Global Property Loss Prevention Data Sheets 7-93 (April 2017), Unified Facilities Criteria (UFC) 4-211-01 (13 April 2017) & NFPA 409 and 410.
