Well, after much trial and error (and some time.. :oops:) I have finally finished the garage door lockout when the screen is anywhere except in its' closed position. I tried interrupting the electric eye circuit with a reed switch (attached to the screen frame and the screen) but that only...

2) good insulation will also help keep IN air conditioning. 9) I painted my ceiling black at one point and ended up repainting it white. The black REALLY sucked the light out of the area and showed off any dust, grit and spider webs that eventually showed up. Anything that sits or lives on the...

Just a couple of small things but easy to overlook or forget. Make sure your speaker wires are rated for in-wall (they are not really much more expensive, and easy to run) and keep any media or data wiring away from any A/C 120 volt wiring as much as possible. If you have to cross, cross at 90...

Oh, wow. That might just work. Let me try and wrap my brain around that for a second... Yes, that's very elegant. Intercept +DC from either one of the electric eyes, send it to the COM on the magnetic reed switch attached to the closed position of the screen/housing, out of the reed switch NC...

I'll probably end up at least trying this, in-line, like you say so if either the tension switch or reed switch is interrupted the door won't move. I'm not sure if the logic board will need a restart/reset or have a time-out if it detects the power cut in the circuit since its' job is to...

This is my backup plan. This is good for when the screen is fully deployed (all the way down); all I would need to do is move the electric eye sensors up and out a bit. I also use the screen as a blind to block the row of windows at the top of the door at night time. The screen in this mode...

This is all I could find...

I have added a motorized projector screen to my garage above the garage door which has a LiftMaster 3800PC attached to it. I would like to attach a magnetic reed switch to the projector screen/housing to disable the door from opening when the screen is deployed. When the reed switch is apart...
