The first model will cost about six thousand rubles, and the second - about two and a half thousand. The range is quite large, but there is a reason to overpay for that. Functionality and efficiency, which has "Astra-812", an order of magnitude higher than that of "Astra-713". But what does the buyer get for this kind of money? What features and modes does this device have? About this below.

"Astra-812": user's manual

So, along with the box and the device itself comes the instruction manual. It describes in detail the entire functionality and principle of operation. In addition, the book describes all the buttons and designations of the device "Astra-812", namely - what is responsible for this or that button. From the instruction it is possible to learn that the device has a special magazine, where the entire operation of the device is clearly described.

Modes of operation of the device

As already mentioned above, there are several modes of operation of the device "Astra-812". The instruction manual lists them all and explains the principle of working with them. In this part of the article the reader will also be able to learn more about them.

Basic

Considering the regimes, it is necessary to clarify that it will be more correct to speak not about the nature of the device operation, but about the operating mode of the relay that are installed there. There are two such relays. There are three systems of work:

1. The first mode is "Sound". If this mode is enabled, the first relay will be open, if the alarm loops (AL) of the so-called guard type are normal. And this relay will be closed if there is at least one AL going beyond the established limits. The second relay is also capable of operating in this mode. It will be opened if the fire alarm system is normal. And it will be closed only when there is a way out of the established limits of one of the AL.
2. The next mode is "Alarm". The first relay will be closed, if everything is normal, and is open in case of exceeding one of the AL limits. The second fire type relay works exactly the same way.
3. The last, the third mode - "Control lamp". The principle of operation of the two relays is similar to the principle of operation in the second mode.

These are all modes of operation of the Astra-812. The instruction describes them in more detail.

Appearance of the device

On the modes everything is told, about the configuration too. And what is this device? Its size is somewhat like a doorphone installed on the door of the entrance. On the front side of it is a small screen. It is quite informative. It reflects the time, date, mode of operation of the device. The screen is liquid crystal, does not shine. Another thing that pleases him is the ability to adjust the backlight level. In other words, it can be made either brighter or darker.

Under the screen, on the left side, you can see four arrow keys in a different direction. These arrows are used to navigate the menu of the device "Astra-812". The center keys are the number keys from 0 to 9. On the right there are four more buttons: "OK", "C", "*" and "#". The buttons are of medium size, so it's quite convenient to use them. On other models, these keys are much smaller, and clicking them is not as convenient as here.

On the back of the device you can see the USB connector, fasteners to hang the device on the wall, a rather large hole for connecting the necessary wires to the device. Interestingly, the back cover of this device opens. Usually there is either a hole or some kind of tongue to open the lid. There is neither one nor the other here. But there is a convenient button on the back of the case. It should be lightly pressed, and everything - the lid is open.

Let's talk a little about installing this device. First you need to make the necessary holes in the wall. Next, you need to open the cover of the device itself and push out in any convenient way the plugs that initially cover the hole for inputting the wires.
