DMPR-RS307 Johnson Controls Damper Control Accessory

Overview

The Johnson Controls DMPR-RS307 is a Style A fusible link damper control accessory engineered for critical thermal protection in commercial HVAC systems. It serves as a passive safety component designed to melt and trigger the mechanical closure of damper blades during an extreme temperature event, preventing the spread of fire and smoke through the ductwork.

Features

• Style A configuration designed for precise compatibility with specific Johnson Controls damper assemblies.
• High-temperature thermal trigger calibrated to activate reliably at 285 degrees Fahrenheit.
• Durable design constructed to maintain integrity under normal operational stresses until the temperature threshold is reached.
• Essential safety mechanism for building fire safety compliance and occupant protection.

Specifications

• Model: DMPR-RS307
• Temperature Rating: 285 degrees F
• Link Style: Style A
• Component Type: Fusible Link Damper Accessory
• Manufacturer: Johnson Controls

Applications

• Installed in fire dampers, smoke dampers, and ventilation ductwork within commercial, industrial, and institutional facilities.
• Applied in building automation and HVAC systems where a high-temperature automatic mechanical shutoff is required.
• Ideal for specific zones demanding higher thermal thresholds for passive fire protection.
