Shockbox 45A01776/935SB - Fire Extinguisher/Detection Test Box BeechJet 400 Series

The Shockbox 45A01776/935SB - Fire Extinguisher/Detection Test Box is a dedicated tester for the Beech 400/400A fire extinguisher and fire detection system. It is required to perform the fire detection system functional test described in the Beech 400/400A maintenance manual (Chapter 26-20-00) during C-check and other scheduled inspections, giving technicians a controllable interface to verify detection loops, extinguishing circuits, and cockpit indications.

By replicating the functionality of the OEM test equipment, the 45A01776/935SB lets maintenance facilities bring essential fire detection testing in-house while following the published procedures. Although built with Beechjet 400/400A operators in mind, the box’s approach to testing fire detection and suppression circuitry can also inform test methodologies in other aircraft types and even in ground-based systems that use similar detection and control logic.

Key Features

• Fire extinguisher and detection system test box for Beech 400 and 400A aircraft.
• Supports the fire detection system functional test required during C-check inspections per the maintenance manual.
• Provides an interface to detection loops, control relays, and cockpit indications for comprehensive system verification.
• Built as an OEM-equivalent solution so shops can perform required tests without sourcing scarce factory equipment.
• Enclosed in a robust case for protection and easy transport around the hangar.
• Ideal for Beechjet maintenance organizations and applicable as a reference for similar fire detection test setups in other industries.
