Our guide to measuring and fitting electric curtain motors. Here at M-Systems we understand the challenges with integrating technology into every day life. However, as the world moves into the realms of home automation and IoT (Internet of Things) these changes will soon become the norm. So, in order to help we have compiled some bits of information below that are designed to make life as easy as possible;
Length – How long does your curtain track need to be? That will depend on the style you want, but as a standard its recommended that you measure for the width of the window plus and additional 30/40cm, this will ensure your curtains will comfortably cover your window. Also your track should be approximately 15cm above your window.
Using the below diagram as an example the window opening itself is 145cm, so the curtain track is measured at 185cm and the curtain box around gives 5cm gap at each end.
When it comes to brackets, we will supply based on the following calculation, starting a 1 meter we will supply 2 brackets and then an additional bracket for every additional meter, Also depending on your chosen option it is possible to hang our tracks against the wall or on the ceiling. the images below depict how this is done.
Multiple Tracks – Good news for those who wish to automate both a netting along with an over curtain, with the use of our multi channel wall controls and remotes its possible to have two layers of curtains within the same windows and control them both with the single remote or wall control, to ensure that you have the available space needed to hang both tracks please review the below guide.
Angles – As all windows are not the same we are able to supply angles at both 90 and 135 degrees in order to fit the most common bay and recessed windows. However, measuring for these can be a complex task, so in order to ensure that you have the correct measurements by reviewing the below guide.
In order to measure the correct length for a Bay or Corner window obtain the lengths of A and B for a Corner Window or A, B and C for a Bay Window (for Bay Windows also gather measurement D so that we can validate that the measurements and angles are correct) . After, add the lengths (A+B or A+B+C) together and purchase from the sizes available including the number of bends needed. Please note that tracks for Corner and Bay windows will be reduced in size by 3cm to allow for the wall/ceiling brackets to be fitted.
Example 1 – A= 128cm B= 171cm , Total= 299cm, for this you would purchase the 300cm track and one 90 degree bend.
Example 2 – A= 89cm B= 91cm C= 89cm, Total= 269m, for this you would purchase the 300cm track and two 135 degree bends.
The below table is a guideline of the supported weights for each track configuration
|Track type||2m Track||3m Track||4m Track||5m Track||6m Track||8m Track||12m Track|
M-Systems recommends that only competent and certified professionals should work with electrics. However, our curtain motors consist of a simple 240v 3 wire and 4 wire system,
3 Wire Systems are used within our RF motors and consist of a single power, neutral and earth, controlling the operation of the motor is done via the remote or an RF bridge/transmitter. For more detail see the below schematic.4 Wire Systems are used within out standard motors, these utilities two power connections (one for Open and the other for Close operations), neutral and earth. For more detail see the below schematic.
Home Automation allows you to control many aspects of your home or office environment, from your heating/cooling, lights, Audio Visual systems, security, the power for home appliances and now with the onset of IoT (internet of things) this control is expanding tremendously into actually controlling the smaller aspects and functions of these appliances!
Now this is where things get interesting, ever wanted to automatically have your curtains open in the morning and close in the evening based on a schedule or even sunset and sunrise? Or how about increasing your properties security by having your curtains open and close at different times each day when you are away? Well, there are multiple possibilities of integrating your curtain motors into home automation, from the simple to the not so simple. Below we have gathered some information to help simplify this as much as possible.
Remote Controlled Motors
The Remote Controlled Motors in our shop come with RF remotes, this will allow you to control your curtains with ease and simplicity. the RF controls work on a 433.92 frequency and can be replaced or supplemented by the various options below;
Also available in our shop are Single Channel with Timer remotes, these remotes allow you to set a simple time for Open and Close each day of the week. once set, the remote will send the signal to the curtain motor initiating the open or close operation, this is a cost effective solution for a single curtain motor that allows automation whilst still having a manual control over the curtains.
There are various RF transmitters on the market that will allow you to control your remote controlled curtain motors, essentially these ‘hubs’ operate with the same RF frequency as our remotes and are usually a static device with no buttons, these hubs bring multiple advantages such as being able to control the curtains from a mobile phone application, operation scheduling and the ability to control multiple devices within the same unit, additionally they are also able to use the same interface to control various IR devices. Some small disadvantages come into play in the fact that they are not a quick ‘to hand’ operation as you would get with the supplied remote (even opening applications on your phone takes time) also some frequencies may not travel to through multiple walls to other rooms depending on the build of your home.
Home Automation Controllers
Similar to ZWave (which we will cover shortly) there are various controllers on the market that utilize the RF frequency these controllers are similar to RF hubs except they are more developed and come with a lot more features. This is truly stepping into the world of Home Automation, even some of the Home Automation Controllers that do not have built-in compatibility for RF are able to use RF Bridges, for Example Vera Plus (Which predominantly uses ZWave) can be integrated with the RFXtrx433 Kit, this allows you to control both ZWave and RF devices which will broaden your home automation control as long as you can learn and re-emit RF commands.
Initially, the standard motors are controlled by using a wall switches, however the common usage for these motors is to be integrated into a Home Automation system, this can be done with the use of a Z-Wave Roller Shutter or Curtain Module, although we do not personally supply these modules (Yet!) they can be purchased from various online retailers, some examples of these relays are;
Wall Switch with Timer
Another product that we are also looking to develop into our offering is a wall mounted switch which offers a timer functionality, this work in the same fashion as the remote timer but is contained within a wall switch with a display. This switch will also be able to control two layers of curtains (mesh and fabric) – coming soon.
Z-Wave Shutter/Curtain Modules
Z-Wave Modules are small devices which can be wired into your electrics and communicate with a ZWave gateway. The gateways often have a mobile application that is used to interface with the devices, set them up to timers or trigger the actions based on events plus control the various other home automation devices that you may have in your home or office. Examples of ZWave modules are the ‘Fibaro FGR-222 Roller Shutter’ 2 or ‘Qubino Flush Shutter DC’.
Optional ZWave Remote
Although Z-Wave gateways provide scheduling and triggers, if you want to control your curtains quickly and dont want to reach for the phone or tablet, there are various Z-Wave remotes on the market that will operate in the same way as out RF Remotes, these can be programmed and used to operate the ZWave module.
ZWave or RF?
So now I hear you ask ‘What Does ZWave Control give me that RF Control Doesn’t?’. Well that was quite a bit of information to take in, now its about deciding which technology you would like to use, are there any benefits to ZWave over RF? Well yes, some! ZWave allows for status reporting from the ZWave Modules, so not only can you trigger a module to perform an action, but you can also get it to report back the power consumption being drawn by the device, also get the module to report the current status and tell you if your curtains are open or closed, this can then be used in scenes and triggers, for instance if the curtains are closed and your motion sensors in your bedroom detect that you have got up before your usual alarm then it can trigger the curtains to open at that point. Sounds amazing right? It is… but like everything there are disadvantages, for instance ZWave is a little more expensive than using RF (LightWaveRF) and ZWave Modules require a ZWave Gateway, where as an RF Hub can work independently with your phone, so ZWave certainly has a bigger investment but can of course achieve greater results.
