It releases.
12, antitheft door has a rechargeable battery, automatic charging, and when mains failure, battery can continue to power, and can continuous work
72 hours or more, red indicating light flash for prompting when cell voltage deficiency.
13, emergency key is had, unlatching burglar-proof door when being available in emergency.
Three, the management of fingerprint
1, the storage, deletion of fingerprint management, that is, fingerprint, it is necessary to be carried out in the state that antitheft door is normally-open.In controller
On operation panel, each indicator light represents one piece of fingerprint.Indicator light is in and is always on state, shows the position stored fingerprint,
Otherwise corresponding indicator light flicker.Any fingerprint is not stored when manufacture.
2, the storage and deletion of fingerprint is divided into 1,2,3 three rank using hierarchical approaches management.Controller differentiated control
Schematically as follows：
1st, 2 piece (red indicating light) is 1 grade of user.
3rd, 4,5 piece (yellow indicator lamp) is 2 grades of users.
6th, 7,8 piece (green indicator light) is 3 grades of users.
If 3, you are 1 grade of users, opening anti-theft behind the door, can will be stored in 2 grades of users and 3 grades of users's (the 3-8 pieces)
Fingerprint is deleted or other people fingerprint is stored in 2-3 grades with indoor, and 1 grade of user can manage mutually, 2 grades of users and 3 grades of use
It cannot be managed mutually between family.But if the position of 1 grade of user does not store fingerprint, 2 grades, 3 grades of users can after normally-open
Fingerprint to be stored in the position of 1 grade of user.
If 4, your fingerprint is stored in 2 grades of user locations of antitheft door, you, can be by the fingers of oneself after normally-open
Other people fingerprint is stored as 3 grades of users by line record deletion, but you cannot store, delete 1 grade of user or peer user.
If 5, you only have the right after normally-open opening antitheft door by the finger record deletion of oneself for 3 grades of users.
The storage of fingerprint operates：
1, after antitheft door is normally opened an account.In door opening state, the corresponding function key in controller is pressed, checks that each position refers to
Line storage condition, indicator light, which is always on, indicates the position stored fingerprint, and indicator light flicker indicates that the position does not store fingerprint.
2, selection presses finger on fingerprint collecting window without a position of storage fingerprint, firmly moderate, presses and " deposits
Storage " key, the red indicating light on operation panel is bright, and fingerprint acquisition instrument reads finger print data, and reading terminates, and red indicating light goes out,
It hears prompt tone simultaneously, moves finger at this time, wait a moment, data storage terminates, and can hear prompt tone, and green indicator light is bright,
Repeat the process twice, the corresponding indicator light on controller is bright, shows that storage operates successfully.It such as cannot correctly acquire three pieces of qualifications
Fingerprint, then this piece of fingerprint will not preserve.
It is recommended that：In order to obtain better effect, when acquiring fingerprint three times, the position of appropriate mobile finger.
Locking operation：
Antitheft door is pushed to, electric control lockset is automatic locking, is simultaneously emitted by prompt tone, and system enters electricity-saving state.
Opening operation
1, antitheft door is in off position.
2, the finger of fingerprint will have been stored by fingerprint collecting window, it is firmly moderate.
3, finger contact induction contact can hear prompt tone, while red, green two indicator lights are each glittering primary.
4, then, red indicating light is bright, indicates that fingerprint collecting window is reading in finger print data, finger will be kept not at this time
Dynamic, red indicating light extinguishes, while hearing prompt tone, shows that finger print data has been read and finishes.
5, finger can be removed, and system is comparing, and examine finger print data that can hear prompt if compared successfully
Sound, while green indicator light is bright, lockset automatically turns on, and can open cabinet door at this time.
6, it can see that the corresponding indicator light of controller is bright after opening the door.
Antitheft door does not store fingerprint when 7, dispatching from the factory, and in the case, powers on, finger touches sense contact, lockset
It can automatically turn on.Once storing fingerprint, it is necessary to use fingerprint or emergency key unlatching burglar-proof door.
The deletion of fingerprint：
1, antitheft door is normally-open.
2, door is opened, the key in controller is pressed according to level-right, chooses the fingerprint to be deleted, pressed " deletion " key, listen
To prompt tone, while green indicator light is bright, shows delete operation success.
Emergency opening antitheft door：
1, when antitheft door fingerprint recognition system cisco unity malfunction.
2, when the fingerprint recognition system of antitheft door is by artificial destruction.
3, have the right unlatching burglar-proof door personnel fingerprint it is impaired when.
Occur that dedicated emergency key unlatching burglar-proof door can be used to tighten palladium situation.(see emergency opening operation instruction).
Operation irregularity processing：
1, when break down in system use cannot be opened with fingerprint when, the emergency key provided by factory can be provided
It opens.
2, the emergency key that producer provides grows 30 centimetres, and head is made of special material, has the function of anti-copying.
3, the jack of emergency key holds key at the side of antitheft door, use with the right hand, the magnetism on key head
Fritter is upward, is horizontally inserted into keyhole, when feel there is magnetic force to push out key when, it was demonstrated that key is already inserted into lock core,
Then 90 degree of the shank of the key is rotated clockwise with hand, hears a sound of " clatter ", while key rotation is motionless, is pulled outwardly at this time with hand
Dynamic emergency key pulls out the keeper of safe-guard door lock, and antitheft door is opened.
Pay attention to：This antitheft door emergency key is placed on safe place, is taken care of by special messenger.
Points for attention when use：
1, button prompting：An on ＆ off switch is often pressed, can hear prompt tone.
2, miscue：Operate it is wrong, (such as：Go beyond one's commission management fingerprint, fingerprint verification it is unsuccessful) can hear that continuous three sound carries
Show that sound, red indicating light are bright.
3, position and the angle of finger are paid attention to when user opens every time, are consistent as possible with position when storage, it is firmly moderate.
4, system prompt mistake may occur during storing fingerprint in only a few user, continuous three sound prompt occur
Sound, red indicating light is bright, this is likely due to this piece of fingerprint damage or finger dry and wet is improper caused, can change a finger
Or it is tried again after adjusting finger humidity.
5, it to select fingerprint and compare clearly finger and be acquired storage, and preferably have spare fingerprint, meet finger meaning
It is used when outer damage.
6, special emergency key be not stored in antitheft door, in addition be kept properly.
If 7, the management of antitheft door rank occurs chaotic, it can will be stored in fingerprint all in antitheft door while remove, weight
It is new to determine rank management.While the method for deleting all fingerprints is：After antitheft door is opened, press...with one's finger tight door closing switch, prevents
It steals door electric control lock and is in locking states, pin (storage is deleted) three buttons in controller simultaneously with three fingers, touch refers to
Contact on line acquisition window, is powered on and is worked using system, and all fingerprints can be removed after being kept for three seconds.
8, when there is owing electricity prompt, battery is please charged or is replaced in time, unexpected generation is prevented.
9, the chemical substances such as this product contact paint, alcohol please don't be made, and water is avoided to drench or excessively make moist, to prevent to this product
It damages.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
