The fingerprint reader enables doors to be unlocked using a fingerprint and a RFID card. It is a two-factor authentication (2FA), both components are always required to open a door. Not only one finger or only the RFID card can be used. It is connected using a SmartRelay and can then be connected to an AccessManager (KXP16) via the master-slave mode. The wall reader is surface mounted.

To use the wall reader, a SmartRelay (KXP-2-RS) is required. Information about the relay and circuit diagrams including examples can be found here: Kentix SmartRelay (KXP-2-RS)

Teach-in Process (Enrolment)

Note: To complete an enrolment process, the same finger must be scanned three times. The process is then repeated with a second finger (3-8).

Starting the enrolment process

  1. The device is in standby mode. Status LED flashes yellow
  2. Hold the enrolment card in front of the RFID reader to start enrolment mode
  3. The fingerprint reader will light up and the status LED will flash red. The first finger must be put on the reader within 5 seconds

Teach-in of the fingers

  1. Place the desired finger on the fingerprint reader surface. The successful scanning process is confirmed with a signal tone
  2. The Status LED flashes red twice
  3. Place your finger again on the fingerprint reader surface until you hear the signal tone
  4. The Status LED flashes red three times
  5. Place your finger on the fingerprint reader surface a third time until you hear signal tone
  6. Repeat the procedure (1-5) with a second finger
  7. A signal sounds and the fingerprint reader is deactivated. The status LED lights yellow. Within 5 seconds the RFID card must be held in front of the RFID reading surface

Storage process on RFID card and completion of the enrolment process

  1. Hold the desired RFID card in front of the RFID reading surface. The status LED lights up blue
  2. Keep the RFID card in the RFID reading range until the writing process is completed
  3. The successful write operation is confirmed by a green status LED and a signal tone
  4. The device returns to standby. Status LED flashes yellow

In the event of an error, the LED lights up red and two signal tones are audible. The device switches to standby mode.

Opening procedure

  1. The device is in standby mode. Status LED flashes yellow
  2. Hold the RFID card in front of the RFID reading surface, the status LED lights up blue during the reading process
  3. The fingerprint reader is activated and the reading surface is illuminated, the status LED flashes yellow. Within 5 seconds one of the taught in finger must be placed on the fingerprint reader (step 4)
  4. Place one of the taught-in finger on the reader. The successful procedure is confirmed by a green light of the status LED and a signal tone. The device now returns to standby mode. Status LED flashes yellow

Errors are indicated by a red status LED and two signal tones. The device then switches back to standby mode. If an error occurs in step 3, place your finger again on the reading surface.

Detailed wiring and terminal diagram for two doors with two fingerprint readers

The following wiring diagram shows the general wiring of the SmartRelay module with two fingerprint readers and two door contacts for monitoring the door status. The readers are connected via a BUS (RS485) with a total cable length of up to approx. 600m. As connection cable we recommend I(ST)Y-2x2x0.8 between SmartRelay and reader. The SmartRelay module is powered via Ethernet PoE. The module supplies two 24VDC voltage outputs as PoE splitters to supply the readers and the lock control. When supplying power to the locks (door opener, motor lock, magnet holder), please note that the splitter can supply a maximum of 10W of power. If more power is required for activation, the locks must be supplied with power via an external power supply unit. The advantage of using the splitter and PoE is the simultaneous emergency power supply of the door control when using a UPS at the PoE supplying switch.

  • The two readers are always supplied with power from the SmartRelay module. Power supply and communication bus (A+B) are routed in one cable.
  • The two relays (Rel1+2) can be set to the required logic NC/NO (Normally Closed/Normally Open) via jumpers.
  • The two door contacts at input 1+2 (DI1+2) require a potential-free contact (e.g. reed contact) for connection to DI1+2.
    *The power supply by the PoE splitter can be replaced by an external power supply. This is necessary if the splitter does not supply the appropriate voltage (24VDC) or the required power (>10W).
