AS-24 Fire Detection & Extinguishing Trainer

This fully functional fire detection and extinguishing system incorporates the continuous loop and spot detectors with corresponding controls, indication, and test circuits. This dual sensor simulator features the two predominant systems in the aerospace industry. The extinguisher discharges shop air upon activation of the system. Systems trainer provides a hands-on resource for troubleshooting faults that can be introduced by the instructor to challenge the student.

Typically, the bottle charge is maintained by a breakable seal. We use shop air to discharge from the flexible hose, simulating a bottle discharge.
