Fortunately, fire safety devices have long been invented. Thanks to them, even at an early stage, it is possible to determine a fire and call firefighters on time. This article will introduce its readers to one of these devices. So, the device that will be considered here is Astra-812. This article will tell you about all the nuances of working with this device: what is the equipment, how to manage this acquisition. And now, first things first.
Reception and control device "Astra-812": price
First of all, I would like to talk about the cost of this device. "Astra-812" is not the only model of devices manufactured by the manufacturer. If we consider this model along with others of the same company, then we can say that it is the most expensive. To confirm these words, one can compare the Astra-812 device with the Astra-713 model.
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 something to overpay for. The functionality and performance that Astra-812 has is an order of magnitude higher than that of Astra-713. But what does the buyer get for that kind of money? What functions and modes does this device have? About it below.
"Astra-812": instruction manual
So, together with the box and the device itself, the instruction manual is included. It describes in detail the full functionality and principle of operation. In addition, the book describes all the buttons and designations of the Astra-812 device, namely, what this or that button is responsible for. From the instructions you can find out that the device has a special logbook that clearly describes the entire operation of the device.
Also, using the menu, you can check the operating status of the device, and if there are any malfunctions or errors, the program will immediately let you know about it. In addition, the device is able to work in several modes.
Device Modes
As mentioned above, there are several modes of operation of the Astra-812 device. 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.
The main
Considering the modes, it is necessary to clarify that it will be more correct to talk not about the nature of the device, but about the mode of operation of the relays that are installed there. There are two such relays. Work systems - three:
- The first mode is “Sound”. If this mode is activated, the first relay will be opened if the alarm loops (ALs) of the so-called security type are normal. And this relay will be closed if at least one alarm loop goes beyond the set limits. The second relay is also able to work in this mode. It will be open if the fire alarm is normal. And it will be closed only when going beyond the set limits of one of the ALs.
- The next mode is "Alarm". The first relay will be closed if everything is normal, and open if at least one of the ALs goes beyond the set limits. The second fire-type relay works exactly the same way.
- The last, third mode - "Warning lamp". The principle of operation of two relays is similar to the principle of operation in the second mode.
These are all the operating modes of the Astra-812 device. The instruction describes them in more detail.
Appearance of the device
Everything is told about the modes, about the configuration too. And what is this device? In its dimensions, it is somewhat reminiscent of a doorphone installed on the porch door. On its front side 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 glare. Another thing that pleases him is the ability to control 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 different directions. These arrows are used to move around the menu of the Astra-812 device. In the center are the number keys from 0 to nine. On the right are four more buttons: "OK", "C", "*" and "#". The buttons are medium in size, so it's pretty convenient to use them. On other models, these keys are much smaller, and pressing 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 cover. There is neither one nor the other here. But there is a convenient button on the back of the case. It is necessary to press lightly on it, and that's it - the lid is open.
How to install the device
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 any plugs that originally cover the wire entry hole in any convenient way. After this, it is necessary to carry out all the wires necessary for connecting and fix the base of the device. Further installation is carried out strictly according to the schemes indicated in the operating instructions. When installation is complete, you can close the lid.
Manufacturer's Warranties
The manufacturer of the Astra-812 device says that within three years, buyers can count on free repair. And the life of the device itself is from five to six years. As with any other device, the manufacturer has the full right to refuse to repair if the device has mechanical damage that was caused by the buyer himself. The second possible reason for the failure is improper use of the device or improper connection.
That is why it is necessary to carefully study all the points in the instruction.
Total
Safety comes first. And the Astra-812 device will help ensure this safety. For little money, a person can purchase a guard who will provide reliable protection against fire for many years.
It is important to remember that it is necessary to study the instructions before connecting and starting to work with this device. Only this will help to use the Astra-812 device safely and effectively.
