Add-on actuator: this actuator can be added to our kits when you need to open more than 1 window. This is an adjustable stroke, unobtrusive 12 volt electric window opener for controlling windows and vents. It can be controlled by a simple DPDT switch, or with our wired wall switch. The lift capacity is 20 lb.
You've seen how handy our window blind and shade systems are, now you can use the same safe, low voltage technology to open and close your windows. It is simple to adapt this unit to most types of windows and skylights because it does not need to rotate in any way like hinged units do.
The flex link direct push stroke is also adjustable: 4" (100mm), 8" (200mm), 10" (250mm), 12" (300mm).
The opening/closing force before obstruction is sensed is approximately 20 lbs (9 kg), current consumption is ~1.5 A, protection class is IP32. These units have been stress tested to over 3,000 openings.
If you are planning to use this for a skylight opener, note that you can check the force required to open the skylight by standing on a bathroom scale and pushing up on the skylight with a long broom handle or other suitable pole. If your skylight is heavier than the actuator capacity, you can offset the extra weight with gas shocks, torsion springs or external counterweights.
PLEASE NOTE: Window and skylight openers can be dangerous to children and adults as they normally have a considerable amount of force that is used to draw the window closed and provide security. There is more than enough force to crush fingers of small children and/or cause injury to adults, pets, or other animals.
Dimensions:
Length: 38.2 cm (15 1/16")
Sill Width: 50mm (2.0")
Sill Width including chain nose: 76mm (3")
Height: 34mm (1 3/8")
The linear chain actuator pushes straight out from the fixed housing which lines up unobtrusively with your window frame, fastened in place with mounting screws. Attach the end of the chain actuator to the window with two screws and you're done!
Use it to control the motion of anything you want, including windows, greenhouse vents, skylights, etc. The stroke is also adjustable: 4" (100mm), 8" (200mm), 10" (250mm), 12" (300mm)
If used with our wired wall switch, it can also be interfaced to a home automation system using 2 relays (up/down).
Care should be exercised when these units are installed where adults or children could get fingers caught in a closing window - serious injury could result. Use of insect screens can help eliminate this possibility.
PLEASE NOTE: Whether it is blind motors or window/skylight openers, you do not need to be concerned with high voltage shocks because these units are operated on a low voltage of 12v DC (no shock hazard), using an AC/DC power supply (or 12v DC battery). It is good practice to connect your AC line as close to the 12v DC motor as possible, and to keep the DC line as short as possible, using at least lamp cord (16 gauge) wire for the 12v DC line. You can also use your car battery to test them.
