Simplex Unican 904 Mechanical Combination

Hi guys. My name is Darrel, and I'm head of the tech team here at LocksOnline.co.uk. Thanks for taking some time to tune in and have a look at one of our product review videos. The product that we have here with us today is the Simplex Unican. It's the 904 product model in the 900 series range of Simplex Unican combination locks. This is the deadlocking version, guys, so this one needs to be mechanically interacted with from either the outside and the inside in which to secure the door. So that's really important we do.

The 900 series has another range also of latch operations, where when you close the door, it will automatically lock. And they also have ones that have a key override facility as well, should you need to. This particular one that we have here in front of us today is the deadbolt, or the deadlocking, version.

From the inside here, it's quite simple. What you would do is, if you wanted to engage the lock, all you'd do is you'd throw the bolt over there like that. This little turn, there. And that's more what you're doing is you're basically throwing the bolt over there like that. All right, that's the actual operation. So to close the door, you close the door behind you, and you would need to manually throw the bolt over to lock it. All right? It doesn't automatically lock. It's advantageous, that, for obvious reasons.

It comes with this solid little keep here, as you can see. And that would actually sit there, then, like that there. And that would actually secure and keep the actual bolt then in its frame there like that, nice and sweet there like so. Beautiful, well-built, well-engineered keep there, which is quite important. As you can see, it's got three fixing holes as well, knowing how important the security is on this particular range of locks.

Now, the actual operation, from the outside, is a combination of buttons here, as you can see there. The factory default, if my memory serves me right, is two and four together, and then three. And if I've got that right, that should operate the bolt. There you go. And that's operating the bolt there. Now, to lock it again, you just throw it back the other way. All right?

So when you go out, you open the door. You then close the door behind you, and then you use this turn there in which to throw the bolt into the frame, and that's it. Then it's locked. To get back in again, then, you would have to put in the code, and then you can then throw the bolt back there like that. So that's the operation. That's how it works.

This is obviously the rim version here, as you can see. But they do do some flush keeps as well, if your type or style of frame is such that you need to have a flush keep instead of a surface rim version like that as well. It comes with a range of fixings. The standard, obviously, are to fix it to a wooden door is standard.

To change the combination, I'm not going to go through how to change the combination. But if you're scratching your head and you want to know how to change the combination, you get the Allen key there, and you undo that little bolt there. And that allows you then to get at the combination chamber, and then you would go through the sequence of commands then in how to change the code.

One of the benefits of the Simplex Unican is it's not necessarily numbers. Even though it's got numbers here, it's for you to remind yourself what the code is. It's more of a sequence of events that this particular type of combination chamber works. So if you wanted to have 23575123, whatever, whatever the code is, obviously, for five. Excuse me, I think I said seven there. It's the sequence of events that's important with this particular type of combination lock.

Some types of combination locks, if the code is 1234, that would work. Three, two, four, one would work. Or 1324 would work. With this, it has to be in the right sequence, which makes it a lot more secure. And also, you'll find this particular type of lock in solutions on many sure defence buildings and so forth. The governments of the world like this type of lock. It's a lot more secure than most.

So there you go guys, that's the 904. As I've said, there is a complete different range available as well, latching and deadlocking and key hold variety etcetera. So it depends on what your application is as to whether or not this is the one for you or one of the other range that we have on our website.

If there is more information that you need or you're not 100% sure and you're saying, "Oh, I could do with this" Or, "I need to know that" etcetera, pop us over an email. We'd love to hear from you. We'd love for you to engage with us and hopefully you may become a customer of ours. But one thing I will do now whilst you're here is I'll get one little measurement quickly, because I think it's an important measurement.

If you're thinking of fitting this on to the door, one of the most critical measurements is how far this particular lock will sit in the door as standard. So that's what we call in the industry a back set measurement. The back set there is 65mm. That's from the centre of the combination chamber to the leading edge there is 65mm. So depends on your locking style set up. You might want to check that to make sure that this particular lock will fit on your door.

So once again, thank you very much for tuning in. I hope it's been informative. So for me Darrel, and all of us here at the LocksOnline team, thanks for tuning in and catch up with you real soon. Take care. Bye-bye now.
