SF420 is an IP based fingerprint terminal for access control and time attendance management.
With Wiegand output, SF420 is flexible to connect with ZK or any 3rd party controllers as a slave reader. Wiegand input configures two SF420 units to utilize Master & Slave solution to enable users verification at both entrance and exit. Antipassback function is also enabled to maximize the security level.
Auxiliary input interface allows SF420 to connect with an extra source, for instance, a smoke detector or emergency switch. Once the linkage function is enabled through the machine menu, the device generates an alarm signal and opens doors in case of emergency.
