Access control Basic common sense
Access control basic common sense
1, Which product does Access control there is in system?
Forbids system contain two most:
( 1) , Generate body argue know: Someone in itself hold some special mark as argue know symbol, Is like lines of the palm, Fingerprint, Face equal to
( 2) , Sign recognitions: By external object's special mark as discern symbol, Is like password, IC card, IC card
2, Which thing does Access control contain in system?
Da about can divide into 3 part
( 1) , Controls host computer: Takes charge of receive signal and discern behind signal, Proceeds open close or transmitt's action
( 2) , Door lock: Locks live door body, Unless break or transmit power, Otherwise normal operates not do should automatic open the door   under situation;
( 3) , Other accessory: Goes out switch, Electric power supply. . . . . Wait for
3, What is " Break close " ( Transmit power open the door) ( Fail- Secure) ?
Normally closes under door situation, Lock body not switch on, But take on " Lock the door " Condition, Passes through outside meet 's control system ( Example: Brushes card machine, Reads card machine ) To locks proceed electrify time, Internal machine experience rise action, But finish " Open the door " 's condition, Is like cathode lock.
4, What is " Break open the door " ( Transmit power close) ( Fail - Safe) ?
Normally closes under door situation, Locks body abidingly electrify, But take on " Lock the door " Condition, Passes through outside meet 's control system ( Example: Brushes card machine, Reads card machine ) To locks proceed power-off time, Internal machine experience rise action, But finish " Open the door " 's condition, Is like magnetic force lock.
5, Does break open the door a meet cut power not door big open?
Can fit UPS UPS, Fors example our company 's RF- 7000XX serieses, Even if have change press, Certains press besides function, Adds battery, Then can become UPS, Prevents break form 's Access control inane.
6, " Break open the door " Ok? Still " Breaks close door " Ok?
Basically on, This is a point of view different problem: " Break open the door " : Fitting is used for fire-fighting law, For the most part fires take place 's reason all are wire go off accidentally, Fire scene's heat can make hardware door lock 's gadget melt but can not open the door flee for one's life, Makes many peoples because door lock can not open flee for one's life but bury generate a sea of fire in the scene of a fire, Breaks open the door 's profit is, Once wire goes off accidentally but initiate power cut time, Channel 's prevents smoke damper will action, Obstructs good smog spread outside, People also can easy open the door flee for one's life. " Breaks close door " : Then fitting is used for treasure house, Waits for some property insurances sex compare high Access control occasion, This moment we can use electron machine lock and cathode lock together fit lock heart usage, Once personnel has danger time, Or can usage rotate twist or key open the door.
7, Why installs finish both-way use after door lock, Can not door all the time normal close?
Door lock install finish behind door can not normal switch, This is the major meet 's problem, But, Real reason for the most part not is lock 's problem ( Maybe few is artificial install 's carelessness ) , Just think, A only takes charge of switch 's lock, How does make door be able to right inerrability 's go back to orientation? Certainly won't work! So, Big many problem all is rise root- - - A field spring's quality. Simple say, Supposes a door heavy 120 Bang, Do should will install many little bang number 's field spring? Maybe you will say, 120 Bang will be bigger bang number, But, Some manufacturer make a point of bang number 's problem, 120 Bang 's door, Maybe install 80 Bang, Even will be bang number low door problems, Then following, At beginning usage, Problem not very, Long usage time, Door can not homing, Door regresses speed then slow, Hanger-on droops serious all is in the future gradually emerge 's problem. Also so, As you fit on cut strength lock, Positive pole locks time, Problem emerge, So, Wants install reversible lock time, First works a heart look once 's orientation, Changes a door's field spring.
8, If not does want spend money change field spring, What replace 's means can there is?
( 1) Adjusts field spring: Say difficult not difficult, But unless profession, Or pleases professional bar
( 2) Fixes open the door direction: Change to one-way open the door, To in pull, Or to outside push open the door, Problem then compares little, But or
There is objective installs factor, For example: Doorframe size, Doorframe spacing very will be big ………. Wait for
9, If I want installation electrically controlled lock, Which matter has should pay attention to?
Direction: One-way ( To in? To outside? ) , Both way, Translation?
Material quality: Metal make ( Aluminium alloy, Stainless steel ) , Wooden, Casement door ( There is has not doorframe, Has door have not frame? )
Spacing: Door band goes doorframe's spacing, Can opens close time whether card go doorframe?
Size: Door's size?
Quantity: Single, Or pair of?
Purpose: Does prevent fire door? Godown door? Channel door?
Speciality: Have whethers have not special request? Door a signal output? Time delays. . . . . Wait for?
10, Do what be meant by incomplete magnet?
Simply, Exactly locks body at break behind still remain magnetic force, Result in lock body still adsorb but can not open the door, This is very dangerous matter, Once takes place calamity incident ( For example: Fire. . . . . ) But results in prevent smoke damper can not close also or flee for one's life door can not open. . . ! ! ! A simple deformity magnet defection, But results in life property's loss, This right and wrong always dangerous problem.
