The DSC2000EM3 is a counter balanced electromechanical version of Delta's highly successful DSC2000 crash-rated, anti-terrorist vehicle control barricade system to help protect soft targets, such as hotels, throughout the world. The DSC2000EM3 provides a fast 1.5-second emergency fast time and normal operating speed of five to 12 seconds. Each module is individually counter balanced and can be raised manually with one hand. The barricade's power unit simply plugs into a standard 120v/15A wall socket. One, two, three or four modules can be powered with a single self contained motor drive.
