BeLine’s BL540 is a very heavy bodied lock designed to display strength and style. The BL540 is a cylindrical latch lock that adjusts to European and American standard backsets. Use of the keypad provides access with User Codes and temporary access with One Time User Codes. The BL540’s built in keyfob reader provides access without any codes. For high security areas, users can be required to use a code and keyfob to gain entry. All forms of entry can also be controlled by time. The BL540 is the ultimate DIY installation lock for those who want to quickly set up secured areas. The BL540 offers full control and the ease of use without metal keys. There is still a standard metal key override for peace of mind just in case uncontrolled circumstances demand it. The BL540 is a great high tech addition for any property.
