Think one near a cluster of three bedrooms could pick up glass breakage in any room if the sensor were in the hallway within 20ft radius?

I do not have first hand experience with actual glass breaking but the Fortress customer service is amazing, so I would call them! They even answered my call on New Year's Day! If I had to guess, I would say "no" because when testing/programming ours, I had to have direct line of sight to the glass. Unless, of course, you have the ability to position it so it would be facing the glass of all three bedrooms, keeping in mind it needs an outlet. They do have a radius but I don't believe around a corner would work.

My experience is that the sensor must be very close to the transmitted signal. My opinion is it would not work for cable behind wallboard, etc. Could be a help in sorting out cables you can touch.

I think they consider 4 feet away to be ideal. You should also note the detector will only work on panel doors (you mount it on the top panel) and not solid one piece doors the swing upwards or carriage style.

Yes unless room temperature could go below 32F. Sensors are not reliable if subject to freezing temperatures, generally.

Hey Ben, i put this unit in my hallway and i gotto say its pretty sensitive. I actually had to put a matte scotch tape over it because the light would turn on every time i would get up off my couch. I can't really say that it would work behind glass but i dont see why it wouldnt. Cheers

I don't know about that situation, however it is very sensitive and should detect sense that unless the sensor is infrared and may be reflected.

My unit is mounted at about 9' off the floor in room with 10' ceilings and it detected a CO build up in the middle of the night that could have easily saved our lives. We live in the middle of the forest and during a power outage our back up generators exhaust came into our bedroom through a slightly open window.

Brian I don't think it will work as the sensor will be too far away from the receiver.

it will works through a thin wall if the remote is very close to the sensor

The other answer is just wrong. He only has the illusion of it working some of the time. The fact is motion sensors (of this type) do not function through glass.

It's a cascaded wireless system, so it depends on distance between alarms and walls between.

Yes. I do. The door sensor transmits an open signal and can be read by as many detector/indicators as you want. The range however is limited. My second detector won't work in our bedroom which is at the opposite end of the house, about 50 feet away. So I located it in a spot I would see in the evening a little closer to the doors. If I were you I'd start with one and try it in the places you might want. If it works fine buy another. I like the system. I really thought it was going to be so so because the price was so resonable. It has been completely reliable I the past 6 months.

I put the sensor inside a utility closet at the side of my house. It works great. I would think it would work just fine between a window and screen. Also, there is a round attachment on the back of the sensor that you could put a string around and hang it from that.

Amanda, I have the sensor above a door at the end of my hallway so that it monitors all doors connected to it. I keep the remote in my bedroom that is about 60ft away and it has worked fine. Hope this helps.

yes! It willl also detect fans, stereo speakers,refrigerators, other normal household items. But it's biggest advantage is to identify much smaller and less powerful electo-madnetic anomalies such as insects from another sector the light sprectrum - for instance, creatures from the infra-red and ultra-violet sectors and the less powerful energy left behind from ghosts.\Good luck with your meter and have a lot of fun identifying objects other than by the naked eye.

Not sure what the maximum distance would be, but I put the main panel in the middle of my house and the sensors are locate up to about 30' feet away. Not problem. Also, the sensor are separated by up to 2 walls (plasterboard interior walls) from the panel. Hope this helps.

The further away you are, the wider area the ir sensorfocus is, so if youare looking at a wide area avg for your catedral ceiling it will prob do the job, if specific to a duct then it will have a tough time oroviding an accurate reading
