Review: Must Be Near the Door Unit To Operate! - I tried to test this thing when I first opened the box, and had some trouble because the instructions are very limited. For my purposes, I want the unit to be unlocked when unpowered, and locked when powered. I was happy to see the unit had the bolt retracted in the box, so that seemed likely that it would do what I need. But I didn't know what I was going to do with four wires! So I started experimenting, and no matter what wire(s) I hooked up to which end of the 12V battery I was testing with, or which ones I touched together, I couldn't get the lock to operate. All I saw was a red light come on (when the red wire was attached to positive and the black to negative). I was beginning to think I've already fried the thing from hooking it up wrong when I finally found another review that mentioned a magnetic reed switch. It turns out red to + and black to - is all you need for wiring, but you ALSO need the other unwired box nearby. Then the lock bolt will deploy. This is a nice feature, but I wish I had known to expect it. Once I figured that out, it operates great from my 12V battery. I haven't mounted it to the door yet, but I don't expect any issues. I bought it for a door that has a dart board mounted to it. I have a dedicated spotlight for the dart board, turned on by a light switch, so I figured I might as well use the same switch to power a 12V DC adapter that will drive this latch. Turn on light to play darts, door locks automatically. If it saves one person from taking a dart to the face, it will be worth the little bit of time and money it took to install it.
Review: Great solution for difficult door - This magnetic bolt system is exactly what I needed for a steel door that I had magnet based (magloc) door lock. With a few good pulls the door could overcome the magnetic lock due to the mass of the door and the lower power magnets. This system physically holds the door with a steel pin that drops into a receiver screwed to the door. All we needed to do is power the lock from our access control panel and it worked flawlessly. It even has a magnetic reed switch in the powered head so that power will not return to the unit unless the lower receiver is aligned under the unit. We'll get a few more of these now that we see how they perform.

## Questions & Answers

**Q: there is no wiring diagram how do I wire it?**
A: The wiring come with the product in the box. At least it did with mine. They are pretty reliable.

**Q: Is it water resistant?**
A: Yes, but not fully waterproof, you'd better install it indoor.

**Q: how  do you lock it?**
A: When powered on, due to electromagnetic force, the lock tongue pops out and locks.
When the door release switch is pressed, the access control circuit will be temporarily powered off. At this time, due to the disappearance of the electromagnetic force, the lock tongue is retracted and the lock is unlocked.

**Q: Could two sets of these be installed at the top and bottom of door for extra security?**
A: Yes, you can install two sets together for extra security. We generally only install one set one the top of the door, but if your door has enough gap at the bottom for another one's installation, you can try it.
