M4000
The Smoke Guard Model 4000 Perimeter (M4000) is a code-compliant fire
+ smoke-rated textile curtain assembly which functions as a
vertically-deploying barrier to prevent transmission of smoke and flames, or to provide a reservoir for smoke on the upper floors of an atrium or other open space. This perimeter curtain can be an effective complement to existing mechanical smoke and fire containment systems or additional fire curtains. The M4000 features a pleated, fire + smoke-rated textile curtain stored in a steel housing, typically installed above a finished ceiling, and deployed by an alarm signal from the local smoke detector or from a fire control panel.
The curtain system may be configured in a closed, box-like, condition or in a multi-faceted open-ended configuration with or without side guides, and it does not require corner support columns or posts. The
curtain panel angles may vary from 30° to 150°, and the curtain
assembly can be equipped with an optional obstruction sensor to detect
impediments to the deployment. The M4000 comes in a standard galvanized
finish, with powder coat options available in any RAL color format.
