  Bio-Knob Decorative
Fingerprint Door Lock
 
The tychisystems BioKnob™ is an advance-technology biometric door lock shaped like an elegant doorknob. At the center of the outside knob is a tiny sensor that registers the pattern of users thumb or fingerprint patterns. Up to 1000 users can have their fingerprints enrolled in the BioKnob for entry. Unobtrusive buttons and a small display allow all programming and settings to be done at the lock with no external wiring or computer needed.
Users no longer have to carry keys, or worry about losing or forgetting them. Families do not have to hide keys in the yard, or maintain duplicate sets of keys. Most importantly, there is no danger of strangers finding or stealing keys for unauthorized entry. Temporary visitors can have their fingerprints enrolled, then individually deleted, with no keys to be issued or returned.
Built-in key pad and LCD display for easy operation.
1000 users.
Can be set for always unlocked (passage) mode.
Fits all doors that normally accept a regular knob type latch lock.

Q: How is the BioKnob different from other fingerprint locks?
A: The BioKnob is distinguished from other biometric locks in many ways that are detailed in subsequent FAQs. However, in general: 1) It is designed, developed, assembled and supported in the US (with subcomponents manufactured by a division of the same company in China), 2)it features the latest fingerprint recognition technology, 3) it has a unique, compact form, 4) it features exclusive functions, and 5) it is made of top grade mechanical materials.
Q: How many fingerprints can you store?
A: 1000 people can have their fingerprints enrolled in the standard model BioKnob. Higher capacity units are available on special request.
Q: How many managers can control the BioKnob?
A: Up to 5 Administrators can be designated, and any of them can add or delete fingerprints.
Q: What is the Audit Trail?
A: The latest 1000 entries are recorded by User ID, date and time of day. To retrieve the data, you use the key pad to cycle through the recorded entries which appear on the LCD display.
Q: Can I store fingerprints from several of my fingers?
A: Yes, and enrolling at least two fingers, such as one from each hand, would be useful in case the selected finger is cut and bandaged upbut then you will lessen the number of potential users by each.
Q: What kind of battery does it use?
A: Rechargeable ion lithium batteries.
Q: How long do they last?
A: At least 1000 openings. There will be an alarm to tell you when they are getting weak, at which time there will be about 50 entries more.
Q: How are the batteries charged?
A: You plug in the connector wire from an AC adapter and leave plugged in for about 3
hours.
Q: Can I wire in external power so I don’t have to charge the batteries?
A: Yes, the BioKnob allows permanent connection of power through an external source.
Q: Does the lock come in different colors?
A: We only sell the brass finish.
Q: Can I set up the lock to be unlocked during the day?
A: Yes.
Q: Where are these locks made?
A: In China, like almost everything these days. However, they are made not by anonymous contractors but by the company’s own manufacturing facility set up and controlled by Tychi Systems, Inc. of Salem, New Hampshire.
Q: Can someone break into the lock and steal the fingerprint images?
A: No. There are no fingerprint images in the lock and no way to reconstruct pictures of a fingerprint from the data. The lock senses a thermal pattern from your finger and stores a template of minutia points that cannot be interpreted by anyone else except our lock.
Q: Can someone sneak up to the lock when no one is looking and lift off an image of a fingerprint, then construct a fake finger that can open the lock?
A: Unlike most other fingerprint devices using a small glass window where you impress your finger, the BioKnob has only a sensor strip across which you stroke your finger. The sensor strip senses a thermal pattern. There is no surface to leave a fingerprint. Therefore there is no danger of anyone detecting a fingerprint, duplicating a fingerprint, faking a finger to enter, or even getting an image of your fingerprint.
Q: What is the warranty period?
A: One year against all defects or inability to operate at the premises.
Q: How difficult is the installation?
A: The BioKnob is designed to fit into the standard US door, wood or metal, that has the standard backset of 2 3/8 or 2 ¾ and a standard 2-1/8" diameter hole. For most doors, installation requires only one Phillips screwdriver.
Q: Is the BioKnob weather proof?
A: Yes. It is water resistant against the usual weather elements, such as rain, snow or dust.
Q: Do you lose all the fingerprints if the batteries go dead?
A: No the fingerprint templates are in non-volatile memory.
Q: What kind of sensor does it use?
A: It uses a thermal sensor that is the same one used on IBM’s fingerprint-password keyboard. However, our algorithm is more powerful to handle a much more challenging job: 1) To verify one fingerprint out of a hundred or more fingerprints, 2) to operate within the limitations of a small, battery-operated microprocessor, and 3) to function in an outdoor, weather-prone environment.
Q: What if the battery is totally dead when I come home after a long vacation?
A: The BioKnob has a emergency backup system in such an event. A standard 9 volt is applied to inconspicuous terminals under the lock for temporary powering of the lock.
Q: Can the lock be picked or bumped open like many regular keyed locks?
A: No it can't because there is no key and cylinder.
Q: Can I delete one person at a time?
A: Yes.
Q: Can I delete everything at one time and reset to factory defaults?
Yes.
Q: Can the BioKnob withstand a seaside environment?
A: Yes, the lock has been tested against direct salt water spray for 72 hours.
