They feature electro-mechanical operation with anti-vandal design features and reinforced construction such that they comply with the European DIN V ENV 1630 Class II standard security test. This standard relates to the resistance level of doors against force using tools of class WK2, e.g. screwdrivers, pliers and wedges. Two versions are available, one with single lock cylinder and the other with dual cylinders to permit opening with either one of two keys.
Operation requires a power supply to the swinghandle or mechanical activation which may be provided under control of an existing central access management system, so enabling maintenance of an event log and update of access protocols. An LED indicates when the handle is ready to be opened and stays in that condition for 20 seconds with locked/unlocked status displayed on the LED.
