I have a damaged lock type AD2000-M, at which the 50 programmed keys. Is it
possible these keys used on the locks of the same type, without
programming? Is there a possibility that in the damaged locks Transfer data
to a new lock?

you need to back up with 12v battery

...ist auch keine Sicherheit: - zum einen muss die Zeitkonstante so gewählt
werden das der Türöffner noch ausreichend Zeit zum öffnen hat und - wenn
man die Spannungsversorgung mehrmals ein- und ausschaltet oder man eine
Stromschwankung hat öffnet sich ebenfalls die Tür... ...hier hat der
Hersteller schlichtweg gepfuscht!

thank you for this info, I can see that there is a spot to connect a jumper
right behind the relay that is labeled NO and NC

The way I fixed this was to connect pins 2 & 3 on J2 (NOT the NC/NO which
is J1. That is for the lock. It's a feature that can be turned off, not a
mistake!

the one I got has a back up rechargeable 12v battery that came with it. no
problems with power loss unless you drained the battery dead.

Автор alfie ga (1 год)
That's what I use and if the power is out for over 6 hours it switches to 5
12v batteries.

Автор Pedro Costa (1 год)
and you can do that having a 12V 2Ah battery??

for a fail safe system it doesn't matter any way and as mrevilmax said ups
for fail secure. What do you expect for $10 any way

The answer is "Uninterruptible power supply"....;-)

I was trying to find one of those cheap RFID access control that don't have
that bug, but it's hard to guess by the specs. I see lots of "AD2000-M"
systems (at least in photo) selling on ebay but not all have same specs,
some say 250 users, some 500 users, some 800, and some 1000, there is also
V2000-A and V2000-C but how can I be sure that bug is fixed in other
systems? does any one have positive feedback of other similar models?

this is a great product review but now tell me... how can u fix this...

If it was a magnetic door retainer then it would be open as soon as you
killed the power anyway. Any sensible system would have battery backup.
Besides, if you really wanted in then you could just pop the cover off that
unit and bridge wires. Sure the tamper alarm would trip, but who cares.
Alternatively an RF device or piezo spark generator would probably crash
the processor and cause it to reboot, opening the door while it did so.

I think it is set to "Fail safe" mode also known as NC. It is supposed to
do this in case of fire or whatever. For some uses this isnt required
because you can still open the door manually from the inside independently
of the lock. If this is the case for you, I think you can change the
setting on the panel to "Fail secure" mode or NO. Amongst the electrical
components on the back of the panel there is a small switch which you just
change over to NO I think it is about the top right corner.

Problem? Door access possible for 3 seconds or so after power
is broken and then restored? Hardly a concernable porblem, bub.

Автор Joven Jumantoc (1 месяц)
you might wired it mistakenly... where did you put your led?? it should be
put in NO or NC donnector not 12 volts directly as you said in you video
