LIBO Electric Drop Bolt Lock DC 12V Fail Safe NC Mode Electronic Door Lock for Access Control Security System with Time Delay

This is very sturdy and good . Once lined up properly , it can be used any where and will always work . The best thing about it is if its a door , it will auto close if activated once it detects the door is back due to the magnet positioning themselves correctly

This is a good little lock with just one small issue. The issue is the power with which the small bolt comes out. If you have everything lined up perfectly then you will have no issue. However if the door you are fitting it to, has any movement on its own latch when closed. Meaning the door could be in a slightly different position each time it is closed, then the alignment of the bolt and hole on this unit may not align. The bolt has no chamfer on the leading edge to guide it into slightly misaligned hole. Therefore it won't engage. I fitted this to a door which has a metal frame and is panelled inside with wood (my own creation) but like most doors when shut if you push and pull the door there was maybe 3mm of movement. This is enough for this unit to push the bolt out but not go into the hole on the opposite part of the unit, thus not locking the door even though the green "locked" indicator lights up. To get around this, I was able to attach a magnet I had, to the metal frame of the door ensuring the door was in exactly the same closed position every time. Obviously this wouldn't be possible on a wooden door. So before buying this. I would just see how much play your door has in it when closed. Be prepared to have to play about and adjust your normal catch to eliminate any movement if you are going to install this lock. As a side note for my installation I purchased a 12v power supply (looks rather like a phone charger) and a 12v led indicator, I wired these directly to the lock using the red and black wire. (The yellow and white wire were not needed) I then plugged this into a spare remote control socket I had and hey presto I can lock the door without crossing the yard which is where my door is located or more honestly... The wife doesn't have to cross the yard in her dressing gown to lock up at night when I'm at work. The reason for the additional led indicator light? This lock has a light on the unit itself to show when locked, but what if like me you are on the opposite side of the door to the lock? So I positioned the led where it can be seen from the house. If you wanted to and you had an Alexa enabled plug/socket, you could use Alexa to power it on and off (lock/open) rather than using the remote that I have set up. I have Alexa so this maybe something I do in the future but for now unlocking in a morning and locking at night. I'm happy with the remote switch. Once locked it does appear it would take a lot of pressure to break it open. Remember this lock will unlock in the event of a power failure for safety reasons. So if you are going on holiday or are wanting to protect something very valuable then I would suggest using a normal lock in conjunction with this lock .

Used on a smart plug via 12vdc psu to lock a porch door for deliveries Works perfect once items are delivered can now secure door via an app

Personally I don’t think it’s suitable for commercial applications as it failed after less then 4 months m but in a low use environment it will be fine

I just bought it, so, I didn't install it yet but, I checked it and it works fine. I am going to use it for an inside door. The lock came nicely packed, there are 4 wires coming out of it, 2 for power supply and 2(yellow and white) that I don't know what they are for. When tested I didn't use the white and yellow and it worked fine. I hope to find out what they are for and update my review.

Wasn’t suitable for what I was after, but I’m sure that’d be perfectly fine for a lighter project.

Built in release time is great

Aufgrund der fehlenden Funktionsbeschreibung erstmal ein großes Fragezeichen. Es werden nur 2 der 4 Anschlüsse belegt und das ist die 12V Spannungsversorgung (Rot und Schwarz). Die anderen beiden Kabel kann man abtrennen. Liegen die 12V an, leuchtet die Status-LED erst rot und wenn der Bolzen rauskommt dann grün. Der Bolzen kommt nur raus, wenn man dass Gegenstück richtig positioniert. In diesem ist ein Magnet, der den Bolzen über einen Reedkontakt schaltet. Will man das Gegenstück nicht montieren, muss ein Magnet an entsprechender Position an der Gegenseite eingebaut werden. Geöffnet wird durch Wegschalten der Spannungsversorgung (stromlos offen). Das kann man sehr gut mit einer elektronischen Zugangskontrolle machen, die ein Relais mit Öffner-Kontakt hat. Habe ich so gemacht und funktioniert einwandfrei. Geht der Bolzen nicht ganz raus, weil etwas z.B. die Tür am vollständigen Schließen hindert, versucht der Bolzen im Sekundentakt immer wieder zu schließen. "Klack - klack - klack..." Erst dachte ich, das Ding wäre defekt, doch in meinem Fall war nur etwas Schmutz zwischen Tür und Rahmen, so dass die Tür nicht ganz schloss und der Bolzen sein "Loch" nicht ganz getroffen hat. Muss man erstmal wissen. Seitlich befindet sich noch ein Schiebeschalter, mit dem man eine Verzögerung einstellen kann. Je nach Einstellung blinkt die grüne LED nach dem Schließen z.B. der Tür im Sekundentakt in der Anzahl nach der Einstellung und der Bolzen verriegelt dann nach der eingestellten Zeit. Ist praktisch bei z.B. Türschließern, wenn die Tür im letzten Stück ganz langsam schließt, damit der Bolzen nicht zu früh rauskommt. Ansonsten habe ich das Teil schon einige Monate in Gebrauch und es funktioniert tadellos. Für den Preis kann man nicht klagen. Wäre nur schön, wenn da eine vollständige Funktionsbeschreibung dabei wäre, dann bräuchte man nicht rum zu probieren.

たいへんよかったです 商品も早く届きました

Geel en wit zijn een controle contact. Wanneer de slotplaat weggenomen (opengebroken) wordt werken ze als schakelcontact. Dus ook wanneer het slot niet geactiveerd is kun je de deur beveiligen. Slot en slotplaat gescheiden van elkaar is een actief contact. Een ideal slot, ik ben er blij mee

Ottima qualità,facile da installare,

Lo compre para poner en un unifi acces con su ua-pro y funciona de maravilla, ahora el problema es el propio unifi ua-pro se me ha roto en 6 meses, calidad mala, pero esto si va bien, perfecto
