Hi, guys. My name's 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. And today we've got a range of receivers and transmitters from a company called Sentry. These are very, very basic sort of transmitters and receivers. They are designed that if you press a button, it changes the stage of relays and allows you to control whatever you want to control. Whether or not it be a garage door, you press a button and the garage door would operate. Whether or not it be an access control solution, to say your back door or your front door or an office or even your shop where you turn around and say to yourself, I want press a button and I want to lock or I want to do something by pressing a button remotely.
So the way that this can used, to be honest with you, is only limited by your imagination. It's a fantastic tool that has a degree of universal dexterity depending on your application. We use it primarily and we sell it primarily as an access control solution to allow you to press a button to open a door but you could also press that button to raise an alarm or use it to disable an alarm that you can sound a bell. It's just incredible the diverse choice on uses that this could particularly have if you want to consider going down that road. So the manufacturers have done well. They haven't got it all complex. It's not finicky in any way. It has loads of functions and facilities and features. Has a couple of basic ones, but in the access world and so forth it just does what it says on the tin.
Here's the actual receiver itself. If I was to take the cover off, obviously, this comes with a screw fixing. But if I were to take the cover off, if you could zoom in there for us, Lee, and what I want to try and do is I give you some sort of indication as to what some of the indicated [SP] markers and so forth are. Across the bottom here you've got a row of contacts. I don't know if you can zoom in you might be able to see they're normally open and normally closed and C. Which is the termination for you to actually connect your third-party source whether or not that be an alarm, an access control solution. The NC and NO, etc., stands in our lingo for normally open, normally closed.
Now what would happen in effect is when you press the button that would actually change state from normally open to normally closed and vice-versa allowing you to have the cause and effect that you're doing by pressing the button on the actual transmitter. Now this particular device will work on 12 volts and 24 volts DC so you've got a complete range of diversity there with regards to voltages. Most access control is 12 volts so it's ideal for that particular application.
What you'll also find is it's actually upside down. If I was to show you there as well there's a little link jumper that sits in there. I don't know if you can actually zoom in there enough, but that little link jumper there has pulse and latch on it. Now what that means is that when you press the button, do you want it to pulse? In other words, it will create the result that you're looking for and then go back to its normal state. Or do you want it to latch? In other words, like switching a light on. Press the button, switch the lights on. Press the button, switch the lights off. That's what we would call that latching mode. But you decide what you want to do.
I have a transmitter here as well, this is the single button transmitter. And what you would effectively do is you run your code across there as to what you want your dip switches to be. Now once you've done that you would then go back to this device when it's powered up. You press that button there, this puts this into learning mode, and within a meter of this unit you press the button now and then this unit here will learn this transponder, this transmitter for this particular receiver. And that's basically how it works and you can up to a few of these should you want to work in the same device. So it's a universal tool and it can be used for a whole range of applications. Like I've said before, it's totally limited to your own imagination. Of course, if the power in the relay is designed for roughly about around about an amp worth of switching capacity. Maybe a little bit more. If you need to switch bigger stuff or even get into 240 volts and up into mains equipment and so forth, you'd obviously put in a bigger relay on line then. And this would then control that relay, etc.
So there you go, guys. Like I say, it's totally limited. Sorry, unlimited, depends on your imagination what you want to do with it. It's here as an access control solution. It's available on our website, LocksOnline. Listen, if you got a little information or you need a little bit more advice, or you're thinking, "I got an application for this but I just want to check this or want to confirm that," why don't you, by all means, pop us over an email or use our live chat on our website, or by all means, pick up the phone and give us a call and we'd be more than willing to want to hear from you. Either way, we love to hear from you and more importantly, we love to see you as a customer. Thank you. From me, Darrel, and all of us here at the team, take care and we'll catch up with you soon. Bye, bye now.
