Three Hour Rating - Lay-In

PRICE SPD-FR square plaque diffusers are Fire-Rated Assemblies which are UL Listed (Underwriters Laboratories Fire Resistance Directory) and ULC Listed (Underwriters Laboratories of Canada Equipment and Materials Directory). This design meets time versus temperature test criteria and NFPA 90A requirements.

SPD-FR square plaque diffusers satisfy both architectural appeal and engineering performance criteria. Simple, clean and unobtrusive face design is intended to blend with most ceiling systems.

  • Available in both imperial and hard metric module sizes.
  • Non-adjustable, butterfly type ceiling radiation damper.
  • Designed for use in an exposed grid suspension ceiling (T-Bar Lay-in) with a three hour or less restrained or unrestrained assembly rating. Units must be installed in accordance with the instructions that accompany each unit.
  • Thermal blanket is non-asbestos.
  • Standard 165°F (74°C) fusible link, optional 212°F (100°C) fusible link.
  • Face panel has smooth edges and rounded off corners to blend with back cone.
  • Back cone is one piece die-formed with smooth, aerodynamically designed surfaces and no corner joints. Helps prevent ceiling smudging.
  • The back cone shape combines with the face panel to deliver a tight 360° radial horizontal air pattern.
  • Face panel is easily installed and removed without special tools. Provides access to optional volume controller.
  • Maintains true 360° horizontal air pattern even at low air volumes making it a good choice for VAV applications.
