CrossingGard® Emergency Response Grille

Model Number: ERG-IBC

Emergency Response Security Grilles

CrossingGard® is an Emergency Response Grille designed to help address both security and safety issues in public areas. CrossingGard® provides the security of a locked, rolling security grille - but immediately responds in an emergency situation to fully open automatically and allow safe escape. Our exclusive egress safety grille is always on duty to provide separation control, yet still allows access to an alternate means of escape.

A secure emergency solution that combines secured roll down gate space separation with emergency egress capability. If notified by alarm, if power fails or if the emergency exit push-button is activated, the rolling security grilles immediately execute a fully open position with no electrical requirements whatsoever. Post-event, it can resume the normally overhead security grille closed and secure position with the touch of a button.

The rugged, open pattern interior gates provide security and visibility with little-to-no maintenance. Manual locking or unlocking is not required. When a forced security grille opening is attempted, AutoLock automatically secures any closed rolling grille (while remaining disengaged during normal and emergency operation).

The CrossingGard® provides excellent security grille corridor protection for flexible space requirements, separation control in facilities where emergency personnel need quick access to secure areas, and containment options for openings requiring a means of egress, such as schools and government facilities.

Overview

CrossingGard® Model ERG-IBC provides the following benefits:

• Safety: CrossingGard’s fail-safe emergency response helps save lives. When an alarm sounds, power is lost or if an emergency exit push-button station is activated, the CrossingGard immediately clears the path by returning the grille to its full open position without requiring an electric or battery power source.

• Security: No manual locking or unlocking required. AutoLock automatically secures a closed grille by engaging upon attempt of forced opening. AutoLock remains disengaged during normal and emergency operation.

• Simplicity: No resetting is necessary to resume normal operation. Following an emergency situation, the CrossingGard can be repositioned to the closed position by activating “close” at the motor control station.

• Speed: If desired, CrossingGard’s early installation option system lets grilles to be mounted on factory supplied tubular members before walls are built and before there is a finished opening.
