The NA 16-2P standard demand switch from BIOLOGA convinces in terms of building biology with the latest groundbreaking technology. Despite the double pole disconnection, the design remains unexpectedly narrow with only one PDU TE.
With this demand switch, packed with the latest technology, low-frequency alternating electric fields are effectively banished from the bedroom. Installed in the fuse box, the NA 16-2P Standard keeps an eye on the power requirements of the “bedroom” 24 hours a day and disconnects this circuit from the mains as soon as all loads are switched off. Despite its very compact design, the NA 16-2P Standard is a very robust device.
Demand switch NA 16-2P Standard learns by itself!
The usually one-time adjustment after installation is no longer necessary with this demand switch – a self-learning system is integrated in the NA 16-2P standard mains disconnector. This is very convenient and can be considered a luxury, but this special feature is also reflected in the price (among others).
Another important advantage is the high sensitivity. Biologa has managed to integrate the automatic detection of even the smallest loads >1.5 watts (6mA) into this demand switch. These include LED lamps, bedside lamps, dimmers, refrigerators with bi-metal switch, water beds and hospital beds with digital control and their own power supply as well as all other ohmic loads such as high-voltage halogen lamps (G9), incandescent lamps, etc..
Further details on the NA 16-2P Standard demand switch
Narrow here means half the width of a conventional demand switch with 35 mm. The NA 16-2P Standard presents itself with a width of 17 mm, i.e. there is space in almost every distributor and fuse box. A further advantage is the simple operation and display. The automatic self-learning unit, the operating elements as well as the display elements (single micro button and multi-colour display via “RGB-LED”) make this mains disconnection switch 16-2P Standard particularly user-friendly.
This demand switch also comes as a set with additional external function test in the form of an LED indicator lamp. Plugged directly into the switched room, this allows convenient recognition of the switch-off: light goes out = disconnection has been completed.
We recommend a separate demand switch for each circuit and room. Simultaneous disconnection of several circuits is also possible, taking into account the maximum rated power. However, we would like to point out that all consumers must always be switched off for the disconnection to take place. With several circuits per demand switch, the number of consumers connected to them also increases.
Convincing performance of the NA 16-2P Standard at a glance
- 2-pole disconnection phase/neutral conductor (L1/N)
- mains isolator for automatic monitoring in narrow design, usually for one circuit/room
- self-learning system
- unstabilized test DC voltage for precise detection of the consumers 100 VoltThe volt defines the tension of an electric line. The tension in the power line (copper) defines the number of amperes that can be transported and almost builds the framework for transmission. More DC
- short-circuit and overvoltage-proof according to IEC
- very robust device with 2 years warranty
- incl. mini indicator lamp KO-L for function monitoring directly in the switched circuit/room.
2 turnkeys for double decoupling and DIRTY ELECTRICITY. Another special feature of this mains disconnector!
An active mains cut-off switch is the basis for any electro-biological renovation of a bedroom and serves to protect and relax people. Modern man is literally “under power”, as we have successfully managed to electrify our lives. However, not with the natural direct current but with the unnatural and therefore very stressful 220 volt alternating current at 16 ampereThe ampere is the base unit of electrical current. The electric current indicates how many electrical loads are moved in a certain amount of time. More current strength. Since the entire communication in the body (from the brain to the cell) also functions electrically, this low-frequency electric alternating field clearly disturbs essential functions in the human organism. The associated symptoms are dramatic and belong to the common or civilisation diseases.
Even though the demand switch is the basis, there are also striking technical differences. In addition to the advantages already mentioned, the two-pole disconnection from the NA 16-2P Standard demand switch is another huge difference. With these 2 turnkeys contacts, both phase and neutral conductors are disconnected. This 2-pole disconnection works against the inevitable effect of alternating current, this DIRTY ELECTRICITY, which is actively combated if not prevented.
Building Biology Conclusion on the NA 16-2P Standard demand switch from Biologa
Taken as a whole, this device represents the technological pinnacle of all mains cut-off switches known to us. We ourselves have other good models in our range and have already had the opportunity to get to know numerous other models and brands in our building biology practice at the customer’s premises. No alternative demand switch will be able to compete with the NA 16-2P in the near future, we think. Of course, this powerhouse of performance has its unique price.
GENERAL TOPICS ON THE USE OF DEMAND SWITCHES
Switching off the correct, load-bearing circuits is a prerequisite!
Only when all influencing circuits have been found, the installation of a demand switch is sensible and effective. Proceeding here only according to the circuit diagram is a big mistake. Without checking the walls and searching for the cause, only the electrical circuit of the room will be disconnected and thus usually miss the target. Each wall has two sides and the alternating electric field always radiates in all directions, up to 2 meters. If this is not taken into account, the mains isolator is installed technically correctly by the electrician, but does not achieve the desired result – this is the case in 95% of households with an active mains isolator.
Checking the mains cut-off is essential!
Our experience shows time and again a problem in connection with the control of the actual grid disconnection. Very often we experience patient situations in which the built-in demand switches are broken or have even NEVER switched on. A simple and effective check of the actual disconnection is therefore essential.
With the LED control lamp included in the set, plugged into the room with the switched power circuit, this possibility is created. Only when this lamp goes out does the mains cut-off function work and this only happens when there is no more power consumption, i.e. when all power has been switched off. So check appliances with standby, clock radios and lamps with power cord and yes, sometimes it is also the electric toothbrush in the bathroom.
Important note: Many appliances are permanent consumers, without standby. Check the position of the on/off switch. If it is between the power plug and the transformer, the disconnection from the power works. However, if the on/off switch is mounted after the transformer (mains plug > transformer > switch > unit), disconnection is not possible due to the constant consumption by the transformer. In this case, the only solution is to replace the cable or a socket strip.
Demand switch, energy saving lamps and LED – a problem of the base load!
Don’t be surprised if the energy-saving lamp and LED lighting no longer switch on when a demand switch is installed. The reason for this is the low current needed to “ignite” the energy saving lamp and LED. This switching on may not be registered by the mains disconnection switch alone and the room will remain dark. It may therefore be necessary to help the mains disconnector to “reach under the arms”, i.e. to help it.
For this case, a base load element is available in the shop, which contributes to increasing the base resistance. This ensures that the ignition process of the lamp requires sufficient current, so that the mains cut-off switch registers this. The same applies to LED lamps up to 4 watts. Luminaires of 1.5 wattThe watt (W) is the unit of power that it used to determine output. More (6mA) or more are automatically registered by the mains cut-off switch even without an additional base load resistor. Think of this as a safety net to ensure that the disconnection works in any case.
The power consumption does not increase due to the load resistance. There is no temperature problem as the load resistor only becomes approx. hand warm for a few seconds (during the switch-on process).
One load resistor is required per on/off switch on the wall, unless the load resistor is installed directly at the consumer.
Alternative to demand switch: Shielded cables or shielding materials
With shielded power cables the general problem of alternating electric fields does not arise at all. However, the possibility of this is usually only possible in the case of large-scale renovation or house construction. The subsequent replacement of electrical cables is usually much more complex and also very expensive. An effective alternative to shielded electrical cables are shieldingShielding is the protection from the effects of external fault zones and environmental influences (on a person's health most of the time). More materials. This can also be used to prevent alternating electric fields of the current from being generated within the room or reaching into the room.
Attention to metal in bed – an essential factor
The mattress, duvet cover and bed linen must be taken into account in case of electrical fields. Especially when using spring mattresses or bed pads with silver threads, people literally draw electricity into bed. It is the wrong way to invest in a mains cut-off switch and at the same time sleep on a mattress or bed cover with silver threads, which in turn can effectively attract electrosmogElectrosmog is a colloquial term for all emissions from electric, magnetic, and electromagnetic fields. More as a powerful antenna!
