Demco 9599006 Stay-IN-Play DUO Supplemental Braking System

Demco 9599006 Stay-IN-Play DUO Supplemental Braking System

The Demco 9599006 Stay-IN-Play DUO Supplemental Braking System is an installed towed-vehicle braking system designed for motorhomes with hydraulic brakes. Its dual-signal design requires both motorhome brake-light activation and sufficient deceleration before applying the towed vehicle's brakes.

Once properly installed, Stay-IN-Play DUO remains in the towed vehicle for convenient flat-towing setup. Its compact operating unit mounts under the hood, while the actuator operates the towed vehicle's brake pedal.

Features & Benefits

• Dual-Signal Activation: Requires both coach brake activation and sufficient deceleration before applying the towed vehicle's brakes.
• Designed for Hydraulic-Brake Motorhomes: Engineered for RVs equipped with hydraulic braking systems.
• Progressive Braking: Applies progressive braking effort to the towed vehicle based on braking conditions.
• Vacuum-Assisted Braking: Creates vacuum to maintain power-brake assist in the towed vehicle during operation.
• Adjustable G-Force Controller: Allows the braking activation threshold to be adjusted for the towing setup.
• Integrated Breakaway: Incorporates a breakaway system into the supplemental braking setup.
• No Pulleys, Catches or Springs: Uses a compact actuator to operate the towed vehicle's brake pedal.
• Installed Design: Remains installed in the towed vehicle instead of requiring a portable braking unit to be positioned for each towing trip.
• Simple Tow Setup: Once properly installed and configured, the system is designed for quick activation before towing.
• 5-Year Warranty: Backed by Demco's five-year braking-system warranty.

Dual-Signal Braking for Hydraulic-Brake Motorhomes

Stay-IN-Play DUO uses two separate signals before activating the towed vehicle's brakes. The motorhome's brakes must be applied and the system must detect sufficient deceleration. Requiring both signals helps prevent unwanted brake activation from conditions such as bumps, grades, or deceleration without coach brake application.

The system combines air pressure with vacuum-assisted power braking. Its compact actuator applies the towed vehicle's brake pedal while the operating system supplies the vacuum needed for consistent power-brake operation.

Installed for Convenient Flat Towing

Unlike a portable supplemental braking unit, Stay-IN-Play DUO is installed in the towed vehicle. After the initial installation and adjustment, the system remains in place for future towing trips.

Important: Demco 9599006 is designed for compatible motorhomes with hydraulic brakes. Motorhomes with air brakes should use an appropriate air-brake supplemental braking system such as Demco Air Force One. Always verify compatibility with your motorhome and towed vehicle and follow current Demco installation and operating instructions.
