+ Electric window controls - what happens if there is a power cut?

Electric window openers are supplied with battery powered back up in case there is a power failure.

+ Electric window openers - what happens in the event of a fire?

Electric window controls can be set up and connected to smoke detectors, so, in the event of a fire, the electric window openers will be operated automatically.

+ High level vent electric window controls - what happens if it rains?

Electric window controls can be connected to rain sensors so, if the weather turns, the windows will close once the rain sensors detect rain.

+ How do electric window openers know when to stop opening or closing the window?

Small sensors set at the extremity of the open or closed window will cut the power when contact is made, thereby negating the risk of damage to the windows or the opener.

+ How do manual window controls differ from electric window controls?

In manual window controls, a handle is turned by hand which drives a helical cable which terminates with a connection to the window or vent. The cable typically runs through a steel conduit which is attached to the wall. Electric window controls are operated from a panel, perhaps with a remote control, without the need for the connecting helical cable which is replaced by electrical cabling.

+ How long does it take to install manual window controls and manual window openers?

Depending on the number of windows to be operated, where they are located and where the operator handle will be installed, it can take anything from one day to a few days – or more, if the installation is in a large building or structure.

+ What are manual window openers?

Manual window openers enable easy operation of vents or windows by remote control, by way of a handle and geared cabling or rods, the handle being in an easily accessible location.

+ What is a window actuator?

A window actuator is another name for an electric windows control.

+ What is the difference between an electric window opener and an actuator?

Both are one and the same, both are frequently used and are interchangeable when referring to the components which are responsible for controlling the movement of the window opening system or mechanism.

+ What type of window opener would be best suited to my high level vents and windows?

There are several potential solutions for remote electric window controls and openers, the best way to define which are most suitable is to have a window controls specialist undertake a survey of the property.

+ Which electric window controls are best for buildings?

There are many solutions for electric window controls and electric window openers, so not an easy question to answer. Depending on the number of windows or vents, where they are located and where they will be operated from will dictate the logistics of the best system for your building. Contact our team today for more detailed information and solutions based on your specific requirements.

+ Why are manual window openers less expensive to install than electric window openers?

There are fewer manufactured components to install, there is no electric cabling, switches, sensors or motors to install, hence the lower installation costs.

+ Why choose manual window openers?

If you have windows or vents positioned within a building or structure and they are not easily accessible, remote manual window openers enable simple operation from a single remote position which is more easily accessible.
