Download Product Brochure Visit Supplier SiteCrossingGard® 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.
