The KP-201 also allows for Two doors to be controlled with a single Handkey II. The first door is controlled by the use of the KP-201 Piezo electronic Keypad. The user enters their ID number into the KP-201 Keypad. If the ID number resides in the HandKey II, the user will be allowed to open the first door. The second door is controlled solely by the HandKey II. The user would follow the normal HandKey II entrance procedure to gain access to the second door.
