This lock uses the touch of a registered fingerprint to unlock the door.


Whenever a new type of security device is introduced, it takes time for that type of device to be generally accepted into the market. Biometric devices have been around in various forms for at least two decades. Hand geometry readers, face and voice recognition systems and retina scanners have all...

After verifying smooth lever operation, reinstall the lower cosmetic screw. If any lever binding occurs, loosen the mounting screws and re-align.

Install the 4 AA alkaline batteries in the holder and replace the battery cover. Since no fingerprint access is allowed without batteries, be sure to keep the emergency keys available for emergency override.

PROGRAMMING

The HFP110 programming kit is required to administer fingerprint management and other programming functions. Twenty programmable time zones provide for timed restriction and free ingress or passage mode operation. (Photo 7)

The HFP110 is specially designed to program the HFD112S. With the kit, the fingerprint templates stored in the lock can be copied and transferred to multiple fingerprint door locks without having to register users individually at each lock.

The kit is also used to program the lock to work in different modes and set the internal clock. The manager can download events logs from up to four different HFD112S units at one time. With each standalone unit having an event log capacity of 8,192, the programmer can hold 32,768 event records. Alternately, the programmer could download 2,000 events each from 16 different locks to reach the 32,000-event level.

All downloaded events can be printed out directly from a printer without the need for a PC, or can be exported to a PC with the optional connection kit (CD-ROM and cable).

The HFP110 uses 2 AA alkaline batteries and has an automatic power shutoff when not in use.

OPERATION

The memory retains the last 8,192 events. Like other audit memory storage, when that limit is reached, the next event causes the oldest event to disappear from memory. Each user can elect to enroll one or two fingerprints.

The door lock must be set up before normal operation. It requires at least one master fingerprint to be registered. To unlock the door, use a registered fingerprint to activate the trigger switch inside the fingerprint capture window. Then place the finger on the sensor. (Photo 8)

If the fingerprint matches one of the registered users, green LED will turn on with a short beep and the door will unlock for five seconds. If the red LED flashes with a long beep, it means the fingerprint is not recognized or is not authorized.

Note: As mentioned above, the lock can only be unlocked with the emergency key when no batteries are installed. With the batteries installed, if there are no user or master fingerprint templates registered in memory, the door lock can be unlocked by pressing the trigger switch without verifying a fingerprint.

If the battery power is low, the red LED will flash three times with three short beeps when the trigger switch is activated. The lock will operate normally for another 300 operations after a low battery status has been identified.

Normal users can be restricted or the lock can be put in passage mode by programming or the use of a master fingerprint. In ‘free ingress’ or passage mode, anyone can push the trigger switch to unlock the lever. A normal five second unlock will occur then the lock will revert to the locked mode.

For cold weather installations, the use of lithium batteries is recommended instead of alkaline. Never mix old and new batteries. Replace all batteries when power is low.

To use the emergency key override, remove the outer key cover with the small spanner wrench. Loosen the cover and unscrew by hand. After using the key to unlock the lever, remove the key and replace the cover. The door will relock when the key is removed. (Photo 9)

CONCLUSION

This is a great alternative for small and medium office use and gives the customer a high-tech security device that they can use to track and control employee movement.

Other Herald biometric products include the HFD101S for residential use - no programming kit required (Photo 10), the HFA200S Fingerprint Access Control Unit (Photo 11) and the HFA300S Fingerprint Time and Attendance System (Photo 12). The HFA220S Access Control Unit with Logger, HFE220 Enrollment Station and the HFP300 Portable Data Bank are all currently under development.
