CrossingGard^® Emergency Response Grille

Emergency Response Security Grilles

CrossingGard^® is a secure emergency solution that combines secured roll down gate space separation with emergency egress capability. If notified by alarm, power fails or 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, the Link 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.

Operation

The AlarmGard motor operator is supplied as standard to provide daily operation along with fail-safe automatic emergency opening capabilities without the use of batteries or a back-up power source. Operator can be recessed above a ceiling, as no mechanical resetting is required to resume normal operation.

International Building Code Compliance

The following items must be installed as indicated for CrossingGard grilles to meet IBC code requirements:

• Fail-safe emergency response opening capability
• Our unique AutoLock mechanism
• Emergency exit push-button opening device
• Additional "push to exit" signage

Additionally, activation by the emergency exit push-button station can be configured to activate a local horn and strobe alarm. Consult Cornell if other details regarding appropriate applications are required.

Aesthetics

Hood and Operator Covers

Metal cover to protect the coil or operator from exterior weather, debris or to meet OSHA or UL 325 safety requirements.

Trim Package

In applications where exterior aesthetics are important, such as hotels, condominiums, convention centers and parking garages, the addition of a trim package can cover unsightly hardware and contribute to the building's architecture.

Powder Coating Grilles

Powder coat finish in more than 180 colors is available on perimeter components such as the aluminum bottom bar, hoods, wall angles, tubes and fascia. This finish is not available on the grille curtain\.

Performance Upgrades

LED Light Kit

The LED Light Kit provides a high-visible status indication for overhead doors and grilles. Designed for challenging environments like fire and emergency services, parking garages, and warehouses, the effective LED light strips limit downtime, maintenance, and repair costs.

Magic Switch

A touchless activation device designed to open and close doors with the wave of a hand. It's compatible with all operators that have a primary entrapment device and are configured for momentary contact to close. The Magic Switch is easy to retrofit in an existing application and features a clean, stainless steel face plate.

Vibration Isolators

Vibration Isolators effectively reduce the amount of vibration* caused by operation of doors and grilles.

*Vibration was reduced by 14% on doors and grilles with Vibration Isolators installed compared to doors and grilles without the system.

Seismic Performance Validation

We can provide project specific seismic calculations for all coiling doors that are mounted Face of Wall to steel or masonry. Seismic performance validation is per ASCE 7-05.

Safety & Protection

Sensing Edge

Smoother Installation and easy maintenance: Designed with a flexible black rubber TPE material, our new sensing edge has two fins that conform to variations in the floor on both the interior and exterior of your door or grille. This ensures a secure seal without requiring you to overset the bottom door limit. The new sensing edge is easy to clean and remains free from rust and dirt stains, maintaining a fresh uniform appearance.

Edges are tested and listed to UL 10B as a component of the rolling steel fire door assembly.

On-the-go Sensing Edge Repair Kit now available. Contact the Service Department at 1-800-390-8590

Stronger weather protection: Featuring flexible 1" sealing fins, our sensing edges withstand the elements, providing maximum protection.

SmartSync™ Wireless Safety Edge & Wireless Remote Controller

The Smartsync™ Safety Edge Kit is an upgrade for our existing Safety Edge. This allows for wireless communication between the transmitter and the receiver, eliminating the coiling cord in the door opening.

The Smartsync™ Wireless Remote comes equipped with an anti-shock design for industrial handling. This heavy-duty remote is compatible with most motor-operated doors, grilles or counter door.*

*Not compatible with NEMA 7/9 operators

Entrapment Protection Devices

Entrapment protection devices ensure that a motorized door or grille will not close on an object. If an object enters path of closure, the entrapment protection device will stop the door or grille from closing and return it to the fully open position.

Unique Design Solutions

Sloping or Irregular Openings

Our special bottom bar designs can address these conditions.
