Gira Keyless in Fingerprint Reader Unit Color Aluminum - Fingerprint module as a professional biometric access control system based on next-generation surface scanning technology. Scanning of the outermost skin layer via high frequency. High recognition rate and tamper resistance. Evaluation of the unique characteristics of a living human finger. Live finger detection. Up to 99 fingers can be managed by the fingerprint reader unit. Reliable recognition of fingers that may have been slightly injured during activities such as gardening (only the outer skin layer was affected). Data protection through encryption methods. Fast response time from placing the finger to unlocking: up to 30 stored fingers in about 1 second, up to 99 stored fingers in about 3 seconds. Night design of the fingerprint area for orientation using white LED lighting. 360° finger placement is possible. Three-color LED status indicator for visual signaling during programming and operation. Master PIN number on the included sealed security card in case the administrator finger is no longer available. The device can be factory reset using the included security card. A confirmation tone for acoustic signaling for users or installers. Alarm sound for unauthorized removal of the fingerprint attachment for sabotage detection. Sabotage circuit with switching actuator in the Gira door communication system. The two integrated changeover relays can be assigned different fingers, for example, thumb: door opening control, index finger: outdoor lighting control. Inputs and outputs: plug strip connection cable for Gira door communication system. Children's fingers can generally only be reliably recognized from the age of 6. Integration into Profile 55 is possible.
