Lens Sensor Choices

In this case the infrared sensors APD-100 allows you to select one of three variants of sensitivity (low, medium, high), while in the model APMD-150 separately given 1 of 4 options for sensitivity to IR-channel and 1 in 8 channel options for the microwave. Due to the large consumption of microwave-head most of the motion sensors combined with infrared and microwave sensor considered ineffective. But unlike them, APMD-150 supports two-way communication, allowing the microwave head turns only when the controller triggers infrared motion sensor. Moreover, if the microwave sensor does not confirm alarm, infrared sensor will regard this event as false, and the system returns to normal operation. Another distinctive feature of new products is the possibility of replacing the lens to increase their range. The standard Infrared sensors APD-100 is equipped with ultra wide-angle lens (EWA) with a viewing angle of 141,2 and a range of 15 m. If required, this sensor can be placed one of two lenses with vertical blinds (range 22.5 m, width 2.2 m ) or a lens with a range of of 30 m and a width of 3m principal ray.

When choosing a lens sensor we recommend that the following rule: the amount of space on the main direction of motion detection should not be less than one third of the distance IR sensor. As a source of supply for APD-100, and 150 are used APMD-CR123A 3V lithium batteries in that ensure stable operation over three years, provided that part-time infrared sensors are not active, but their frequency Poll controller is less than 1 every 12 seconds. Install motion sensors is recommended within the zone of visibility ACU-100 controller. To minimize the risk of accidental masking people, all the sensors and detectors Alarm ABAX recommended to install as possible. To register, radiant heat infrared sensors use a dual pyroelectric element, capable of detecting the difference in temperature between the body and temperature of the background of a few tenths of a degree. Reciprocal subtraction of signals from the two pyroelectric element sensor to filter out noise when convection or air movement coming from the electrical and heat sources. In addition, motion sensors serve two-factor analysis of the signal: the value and quantity, and the thresholds of IR sensors are floating and change synchronously with the signal interference.

New wireless infrared sensors already on the Russian market, and the retail price of APD-100 and APMD-150 is $ 65 and $ 88 respectively.

Boiler room can be located in the basement, if it provided the project can be located at attic, or placed outside the home, in a separate room. (The latter is common in Europe). The first Choose the boiler business. Its capacity is determined based on the calculated data on heat loss at home. For example, if the heat loss amounted to 60 kW, the boiler must be at least 60 kW. This is followed by selection of a boiler. It is chosen based on the average water consumption of the building's residents.

For the boiler must be installed and bolylera expansion tanks, they are purchased from the amount of circulating water supply system. Then, based on the force and pressure of hydraulic losses, pumping equipment is selected. This is followed by reinforcement (valves, filters, a security group kotelnog equipment, cranes, etc.) The choice of a radiator Further, heated for each project selected areas of the house sink, in common battery. The main parameters of the choice of the radiator – this is life, design, heat transfer and price. Click Wells Fargo Bank to learn more. Just choose the radiator will be depend on the design capacity, and the concept of home design. Radiator myriad variations. These vary in size, shape and power, are made of different materials.

Manufacturers of radiators You can find many. The most famous and radiators running brands such as KERMI (Germany), PURMO (Finland) GLOBAL (Italy). By the way on the radiators in the company KERMI LAiN Technology, often held shares, now they can be purchased at a favorable conditions. Contact (495) 620-59-37, learn the details. Summary of a wooden house most of us today live in large cities. Far no secret that long, bezvylazno residence in a city such as Moscow, causing serious damage to health and human nervous system. This is linked with adverse environment, and with the rapid pace of life, followed by harder and harder to keep up. And most importantly, in the city, we live in multi-story reinforced concrete or brick houses. Logically comes to mind is whether to build a stone house out of town, if you live in the city, in fact, in the same. Everybody knows that they come to nature, you feel like in another world – so easy to breathe, so quiet, calm, beautiful, perfectly round. A wooden house surrounded by a garden, where everything is natural, as intended by nature itself, makes it possible to plunge fully with the head in this atmosphere, to merge with her resting body and soul. Of course, in a stone cottage with every convenience and also get a good rest, but his wooden house surrounded by trees, which contains in the very spirit of nature, nor give the incomparable feeling saturate the life force, restore worn in the nervous system. No wonder that in this house wants to come back again and again, and perhaps someday to move there permanently. Eugene Ocean
