Safety and Protection
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.
An electrical cutout switch to prevent motor operation if locking device is not first disengaged.
A wide variety of locking options are available to meet your security needs.
Monitored Protection, Even at High Speeds l
UL 325-2010 (NEMA 4X) compliant photo eye sensors allow for momentary contact operation – useful in parking garages and other high use openings. Interruption of the photo eye beam before the door fully closes causes the door to immediately halt downward
travel and reverse direction to return to the fully open position. .
SafetyGard Light Curtain Technology
The 6’ tall light curtain is installed within the guide and blends into the guide construction. If the grille is cycling and an object passes through the curtain beams the door will immediately halt downward travel and reverse direction to return
to the open position.
