FPV Safe and Arm Switch
The FPV Safe and Arm Switch is engineered for FPV Kinetic Payload Systems requiring controlled arming, pre-arm confirmation, and verified initiation during precision strike operations. It eliminates uncertainty across the full sequence—from power-on through impact—while supporting lethality and enforcing operator safety.
Also referred to as a Safe and Arm Device (SAD) or Electronic Safe and Arm Device (ESAD), this system is designed for FPV and drone payload applications requiring controlled arming, confirmed initiation, and repeatable performance at scale across distributed manufacturing environments.
Safe and Arm Device (SAD) for FPV and Drone Systems
This system introduces a defined pre-arm verification step often missing in FPV applications: confirmation before arming.
Built for real-world deployment, it delivers controlled sequencing, repeatable performance, and adaptability across platforms and payload configurations.
This aligns FPV systems with established ordnance-level Safe and Arm Device architecture while adapting to modern drone payload applications.
Built for Scalable FPV Programs
FPV systems are scaling rapidly across Department of Defense programs, creating demand for standardized, reliable Safe and Arm Devices.
This system is designed to support:
• High-volume FPV production environments
• Standardized integration across multiple drone platforms
• Repeatable performance across distributed manufacturing
• Reduced integration friction for Drone Dominance Program awardees
• Component-level standardization for FPV Safe and Arm Devices
FPV Safe and Arm Switch Key Features
• Safe-to-Arm Indicator for pre-arm confirmation
• Controlled safe-to-arm transition
• Positive confirmation of initiation on impact
• Universal fusing interface for custom contact fuse integration
• Universal output supporting buzzers, squibs, electric matches, and custom devices
• Designed for FPV Kinetic Payload Systems
• Enhances precision strike reliability and lethality
• Reduces risk during system power-on, handling, and initialization
SAS2A (Safe And Arm – Safe To Arm)
This system is built on the SAS2A architecture:
Safe → Confirm → Arm → Impact → Confirm
Unlike traditional approaches, SAS2A introduces a Safe-to-Arm Indicator that provides a clear signal before arming. This reduces the likelihood of unintended detonation during power-on and gives operators a defined go/no-go checkpoint before activation.
Safe-to-Arm Indicator
The integrated Safe-to-Arm Indicator confirms that the system is in the correct state prior to arming.
• Verifies readiness before transition to armed
• Reduces risk during system power-on and handling
• Provides immediate operator feedback
Without this confirmation, arming decisions are based on assumption. This system removes that uncertainty.
Universal Fusing Interface
The FPV Safe and Arm Switch is not locked to a fixed fuse design.
• Integrate your own contact fuse
• Maintain control over payload-specific performance
• Adapt without redesigning the entire system
• Enables rapid adaptation across platforms without redesigning the core Safe and Arm Device
This allows FPV manufacturers to tailor precision strike performance and lethality based on their specific payload requirements.
Universal Output Architecture
Different missions require different outputs. This system supports:
• Buzzers for audible confirmation
• Squibs and electric matches for initiation
• Custom output configurations defined by the builder
• Supports mission-specific configuration without altering the core system architecture
You define the output. The system delivers the sequence.
What Problem This Solves
Many FPV systems operate with gaps in control:
• No confirmation before arming
• Limited flexibility in fuse design
• Restricted output configurations
• Increased risk during power-on
• Lack of standardized Safe and Arm Devices across FPV platforms
• Lack of pre-arm verification in existing FPV trigger systems
This system addresses those gaps by delivering:
• Operator safety through controlled sequencing
• Precision strike through verified initiation
• Lethality through consistent performance
• Flexibility through open architecture design
This system is built under EOD Gear’s New COTS – Custom Off The Shelf approach, allowing configuration based on platform, payload, and mission requirements without starting from zero.
Why The SAS2A System
The SAS2A system operates as a true Safe and Arm Device (SAD), aligning with established ordnance architecture while adapting to FPV and drone payload systems.
Most FPV switch solutions rely on improvised triggering or legacy components adapted to drone use.
The SAS2A system is purpose-built for FPV applications, combining:
• Pre-arm confirmation
• Controlled arming
• Verified impact initiation
• Open architecture integration
This product is manufactured by EOD Gear, a U.S.-based defense manufacturer operating under ISO 9001:2015, CMMC2, ITAR registration, ATF FFL Type 10 / FEL Type 20, and a GSA contract. All systems are designed and produced in-house using CNC machining and additive manufacturing to ensure controlled, repeatable performance.
