Installation of motion sensors to turn on the lighting device characteristics and

Among the various security equipment and alarm systems, which are installed in buildings and adjacent territory, motion sensors are distinguished by their versatility.In fact, they were created as part of an integrated system and is intended to inform about unauthorized access to "controlled by" their territory or premises.Is an electronic device operating in the spectrum of infrared radiation.

As the production of various devices that are used to improve the comfort of living, they were mounted not only in the security schemes, but also used in systems that combine general concept of "smart home".In particular, for automatic switching of lighting at the place where there is a moving object and having a predetermined temperature.To better understand how to select the optimal model for the light sensor switching his home and his (or their) right to install, you should know in general terms the principle of his actions.

When triggered

motion sensor installed device "scans" all the space, entering a sector of its review.What is the size of land "sees" a particular sensor model depends on its performance and the place of installation.It continuously records the level of infrared radiation in the "zone of responsibility", and if there is no change, then the signal at the output does not change.

When in the controlled sector there is an object (person, animal), the temperature of which exceeds the established in the premises (on site), there is a change of the output voltage.Formed a series of pulses which are fed to a control circuit.Depending on how the configured parameter "sensitivity" of a certain number (usually 2 - 3) leads to the circuit chain and thereby causes include lighting devices.

This makes the use of such devices is very convenient for any room, since they provide a non-contact switch is lighting.No need to switch seek the dark, especially when both hands anything loaded.

application features

of the sensors name suggests, it captures only the moving objects.Therefore, it is advisable to install it where the person is short.For the apartment is a corridor (hallway), for private homes - and even the stairs, paths in the territory, and so on.

In addition, they are well suited for installation in crowded places - the corridors and stairwells of administrative, industrial and residential buildings.According to some experts, only for the operation of such equipment energy savings can reach 65%.

It makes no sense to put these products in high temperature environments (such as laundry, sauna) and the vicinity of equipment and pipes of the heating system - the sensors simply do not work.

What to consider when buying

Fastening and characteristics.It should be understood that all devices are different, including the review and sector.For example, it makes no sense to buy a more expensive model, which scans the space for 1800, if the sensor is expected to put in a corner.

should take into account the possibility of working sensors in combination with one or another kind of lighting.For example, depending on its total capacity.Otherwise the product contacts can simply "burn".

Design.Some models have special hinges that enable as necessary to change the position of the device, thereby shifting the field of view in either direction (both in vertical and horizontal direction).

Products can be designed for both outdoor and in-wall installation.It is necessary to pay attention to the degree of protection - against moisture and dust.

Some sensors are supplied from the circuit 12, there is a direct connection model - 220 V.

opportunities for setting up parameters and their limits regulation

Hours before disconnecting light fixtures.What this interval is more, the convenient operation of the sensor.But in order to organize the sequential switching on and off by a person along the line of lamps, for example, along the corridor, this time should be minimized.Such sensors can significantly save on electricity consumption.

limit trigger level for illumination.This feature allows you to adjust the sensor so that it does not include lighting products in good visibility (in the afternoon).

sensitivity.From this setting determines whether false positives, and therefore the unauthorized inclusion of lighting.For example, if a person in a dream turned from side to side.

For example, the sensor 1100 'Control-Suite. "The range "detection" of a moving object -. 12 m It can be installed both inside and outside the house.Adjusting the time before the trip - in the range from 3 seconds to 12 minutes, it can be used indoors for any purpose.Connected load (lighting) - up to 1 kW.Operating current - up to 16 A. The degree of protection involves the installation even under conditions of excessive moisture.Price - 585 rubles.

Model «LX-2000" will cost 1100 rubles.Also during actuation motion, and it responds to sound.This allows you to turn on lights, even from outside the premises.

Installation recommendations

In some cases it is advisable to install in parallel with the sensor supply chain luminaire ordinary switch.If you see a need for long-term stay in the room, then to provide illumination will always have to make any movement, otherwise the sensor "default" is simply turned off the light.

example, going into the living room to sit and read a book, or going down to the basement, so there is something to find.Options like a lot of situations.

must take into account that the installation of the sensor must be carried out at the level of not less than 1 m from the floor.Otherwise, it will operate even when a cat or dog in the room in which the light is known, and is not particularly needed.But on the movement of the child, he should respond.Otherwise, it always have to include the light, for example, in the toilet.

If you plan to put the sensor with a viewing angle of 1800, the best place for him - on the ceiling or wall of the room.Models with a specific review of the sector is set where it is more convenient, but their field of vision must get entry / exit doors.With this arrangement, the sensor light will turn on when they are opened.

When installing the product in a room with several doors need to take into account their location and characteristics of the device.Perhaps that would have to put in one room and 2 sensors that they "see" all the inputs / outputs.In this case, they are connected in parallel.

The field of view should be no objects that would have complicated the viewing space.For example, furniture items.Otherwise, there will be "blind spots", and the sensor will not respond.

As a rule, the housing products (and accompanying documentation - required), there is a diagram of its connection.When choosing a model, you need to pay attention to its features.

Consider whether the parallel is expected to include more coverage of any system?For example, ventilation.
