XPass 2
Dead bolt /
Door strike
Install a diode at both sides of the door lock wire as shown in the figure to protect the relay from the reverse
current, which occurs when the door lock operates.
Use a separate power supply for XPass 2 and the door lock.
Suprema’s standalone intelligent readers contain internal relays that can directly lock/unlock doors without
external controllers for added convenience. For access control applications in need of security, however,
it is NOT recommended to use the internal relay of a reader to prevent any tampering attacks which can
potentially trigger the door unlock. For such applications, it is highly recommended to use a separate relay
unit for a lock control such as Suprema’s Secure I/O 2, DM-20 or CoreStation installed at a secure side of a
door.
Take caution of the installation direction of the diode. Install the diode close to the door lock.
