AutoEject

AutoEject is a critical safety system that automatically disconnects electrical power cords from emergency vehicles when they start up.

When seconds matter, first responders cannot afford delays caused by manual shore-power lines. This technology ensures fire trucks and ambulances can deploy instantly without damaging equipment or station infrastructure. The Problem with Shore Power

Emergency vehicles require continuous electrical power while parked inside a station bay. This “shore power” keeps specialized onboard equipment ready for immediate operation: Recharging specialized vehicle batteries. Powering sensitive medical equipment. Maintaining engine block heaters for fast starts.

Historically, drivers had to manually unplug these cables before leaving. In high-stress situations, forgetting this step resulted in ripped cords, broken plugs, and severe damage to both the vehicle and the station walls. How AutoEject Works

The system automates the physical disconnection process through a reliable electromechanical mechanism integrated into the vehicle’s side panel.

Connection: The power cord is manually plugged into the flush-mounted vehicle receptacle while parked.

Ignition Trigger: The driver turns the vehicle key or presses the start button to respond to a call.

Internal Mechanism: The starter circuit sends a momentary electrical pulse to an internal solenoid.

Physical Ejection: A spring-loaded mechanism instantly drives the plug out and away from the vehicle.

Weather Protection: A protective cover snaps shut immediately to seal the receptacle against dirt and water. Key Benefits for Emergency Fleets

Implementing automatic ejection systems provides three primary advantages to emergency service stations:

Eliminates Human Error: Drivers focus entirely on driving safely rather than checking physical cords.

Prevents Costly Repairs: It stops structural damage to station walls and expensive vehicle rewiring.

Maximizes Response Times: Vehicles exit the bay instantly without a single second of physical delay. Common Configurations

Most modern emergency fleets utilize specialized variants tailored to their specific technical infrastructure:

Standard AC Units: Designed for traditional 120V or 240V station electrical grids.

Combination Units: Single plugs that simultaneously deliver electrical power and compressed air for air-brake systems.

Smart Delays: Advanced versions that delay ejection for a fraction of a second to ensure power is cut before the plug moves, preventing hazardous electrical arcing.
