Keri's B100-SKP-SA Readers provide reliable swipe- Fingerprint reading in attractive and unobtrusive packages. Typically for small and medium installations, these readers can be used in residential areas, homes, offices, gate automations and other applications where high security is needed but simple installation is required. B100-SKP-SA Readers have one integrated relay so you can connect the readers directly to activate devices such as electric locking, alarm systems, etc. For higher security and additional relay needed, the readers could be linked via RS485 to our RU2 din-rail two-remote relays unit in a secured area. The readers can be programmed in a few steps via the Fingerprint sensor via the keypad, running through a simple programming menu provided.
