REX handle

Capacitive sensor

Positioned at just the right height, it enables the user to grab the handle, place the finger on the sensor at the same time and unlock the door immediately.

Buttons for programming

The administrator can add and delete fingerprints with a help of two buttons integrated on the handle. Simple, secure and discrete.

Unlocks the door and turns off the alarm

Two relay outputs enable REX handle to unlock the door with the first one and trigger another device with the second (alarm, garage door, etc.).

Many dimensions and design options

REX handle is available in the length of 600 - 1800 mm, in round, square and flat square shape.

Today, stainless steel handles are incorporated in virtually all modern high-standard entrance doors.

REX handle brand is a line of stainless steel door handles with integrated fingerprint readers.

The convenient placement of the capacitive area sensor on the handle enables the user to unlock and open the door at the same time. On the side facing the user there is a LED indicator while the sensor and two buttons for programming face the door. REX handle has two relay outputs, so it can unlock the door and trigger another device (alarm, garage door, etc.).

REX handle R series is an array of round stainless steel handles (ø 30 mm). It consists of three segments, the fingerprint sensor is integrated in the middle one. It is mounted on the door by two or three either 90° or 45° mounting elements (depending on the length of the handle). The exit of the connection cables is through the upper mounting element.

REX handle Q series is an array of square stainless steel handles (30 x 30 mm). It consists of only one piece with the fingerprint sensor integrated on the side facing the door. It is mounted on the door by two mounting elements (either at both ends of the handle or slightly tilted towards the centre). The exit of the connection cables is through the upper mounting element.

REX handle F series is an array of flat square stainless steel handles (30 x 15 mm). It consists of only one piece with the fingerprint sensor integrated on the side facing the door. It is mounted on the door by two or three mounting elements (depending on the length of the handle). The exit of the connection cables is through the upper mounting element.

REX handle consists of two units: the external fingerprint reader, installed inside the handle, and the internal unit with integrated relays. The internal unit is always placed in the safe place (inside the door leaf or the fuse box). Communication between the units is protected by a 256-bit rolling code which makes hacking the device virtually impossible.

  • Sizes: 600-1800 mm
  • Administrator memory slots: 3
  • Fingerprint capacity: 1000
  • Relay outputs: 2
  • Programming: With two integrated buttons
  • Mounting:  On the door leaf
  • Sensor type: Area capacitive with 3D imaging
  • Hacking protection: 256-bit rolling code

Make sure your hands are clean and sufficiently moist. Fingerprint recognition problems are at their peak in winter months, when your skin is very dry.

Fingerprint recognition is a very sophisticated technology, so it is normal to expect small fluctuations even when using best components available. In reality there are 3% to 4% of people which can't use our products but more importantly, 90% of those are either younger than 8 years or older than 75.

Small children have small fingerprints, plus their fingerprints are still developing and changing. A fingerprint matures approximately at the age of eight. Some of our older user's biggest problem on the other side is very dry skin. REX handle can also be unlocked with the remote control, so our older family members can use it instead of the reader.

Our fingerprint readers use 3D imaging technology and they also measure the conductivity of a finger. This makes it extremely difficult to fool them with artificial fingers.
However, when asking about the vulnerability of the fingerprint reader as a threat to your home security, it makes sense to ask a few other questions first:

  • How will the burglar get quality images of your fingerprint?
  • Does the burglar have the technology and know-how to produce high quality artificial fingers?
  • Burglars are mostly opportunists who will find the most vulnerable point to enter the house: they will simply break a window or break in through a balcony.

If you want to protect high value items on your property, we strongly suggest that you consider employing some guards, and if you go for a biometric solution, choose a retina-scan device. They are big and very expensive but highly reliable.

The relay for unlocking the door is integrated on the internal unit which is stored deep in the door leaf or in the fuse box. The communication between the fingerprint reader (the external unit) and the internal unit is encrypted by a 256-bit rolling code. The same level of security is being used in your internet banking service.

If REX handle for any reason does not recognize your fingerprint(s) there should also always be an option to unlock the door with a conventional key.

You can read about possible causes for this situation as well as tips for solving it in the "Troubleshooting" tab.

The sensor must be clean to make good readings. You can gently wipe it with a moist, soft cloth. Never use aggressive and abrasive cleaning solutions or sharp and harsh tools as you may damage the sensor.

  • The finger was pressed on the sensor too harshly or too gently. The finger should be pressed on the surface of the sensor with normal strength.
  • The surface of the fingerprint pressed on the sensor was too small. A larger surface of the fingerprint should be pressed on the sensor.
  • The fingerprint database is full. You will be able to add a new fingerprint after you  delete one of the existing ones.
  • Skin on the finger you're trying to enroll is very dry. Make sure your skin is moist enough.
  • The device is in the sleep mode. Press one of the buttons to wake it up.
  • For troubleshooting regarding children, the elderly and damaged fingerprints see the last tab.
  • The finger has been pressed on the sensor too harshly or too gently. The finger must be pressed on the surface of the sensor with normal strength.
  • A too small surface of the fingerprint has been pressed on the sensor. A larger surface of the fingerprint must be pressed on the sensor.
  • Skin on the finger you're trying to enroll is very dry. Make sure your skin is moist enough.
  • The device is in sleep mode. Press one of the buttons to wake it up.
  • For troubleshooting regarding children, elderly and damaged fingerprints read the last tab.
  • The device is in the sleep mode. Press one of the buttons for 1 second and it will wake up.
  • The device is not connected to the power supply. Check the wiring for possible damage and check the fuse  on which the device is connected. If the device still does not respond, call an authorized repair service.

Device malfunction. Call an authorised repair service.

  • The finger that you used might be programmed to trigger the second relay. Delete the fingerprint first, then enroll it again and assign it to the first relay. The procedure is described in the user manual and in the quick guide.
  • Device or electric lock malfunction. Call an authorised repair service.
  • If a child's fingerprint cannot be enrolled it means that it is either too small or not developed enough. Fingerprints mature around the age of eight.
  • A child's fingerprint was successfully enrolled but after some time it is not recognized anymore. Fingerprints can change a lot in a short time during development phase. Enroll the child's fingerprints again.
  • Elder people can have dry and less elastic skin. This makes fingerprints harder to enroll and to recognize. Users in this group need to moisturize their hands before enrolling and using the device. They can also enroll the same finger more than once. This will make the recognition easier.
  • Manual labour, especially when it involves the use of chemicals and various cleaning liquids, can lead to damaged fingerprints. The quality of fingerprints can be improved by the use moisturizing hand creams and to increase the possibility of success it is recommended to enroll the same fingerprint more than once. In some extreme cases fingerprint are damaged beyond recognition and it makes more sense to use another solution, such as the REX touchpad or the REX bluetooth.
