I noticed the sensor has a little removable door. Is this used to improve sensitivity by removing it? Or does the little door/cover need to stay on?

The little door can stay on or off. If its off the detection angle will become wider causing the unit to be tripped at a wider peripheral.

Remove door for initial set up and then reinstall upon mounting unit permanently.

I don't believe the sensitivity would be improved by removing it, it is plenty sensitive as it is. If anything, removing the door would be an invitation for insects to occupy it and you do not want that.

No, but if you put something over the sensor like electrical tape or something it would stay on

Not sure what you mean. It is very sensitive...it will go off with the slightest pressing on the top...from either side of the door.

No, there is no on/off at the sensor. If she tries to take it off or anything like that it will seperate at set it off. It works like a charm. Use the alert channel #4

Yes it is removable. It is not meant to be removable but you simply pop it out. There is a YouTube that shows someone doing it. I kept it and haven't noticed any problem with sensitivity.

You will need to cut a small piece of wood and place behind the sensor to make them flush. It is also recommended that the sensor be stationary and the magnet be on the door, to prevent unnecessary wear on the device.

I think the reason the sensor is on the bottom, is that the unit is usually mounted under an eave or ledge, and this allows the daylight that turns the unit off better access to the sensor. My main grip with this type of unit isthat it usually turns on in the evening well before it is even remotely dark, and stays on well after it becomesreally light in the morning. The problem you mention of the unit cycling on and off can happen. It is usuallycaused by bad positioning of the unit. The light from the unit can reflect off the building causing the unit tocycle on and off. It can usually be taken care of by repositioning the unit, or by providing some sort of shield-ing.

Hi Bob, there are two sensors on this model; 1) there are electric eye sensors that are mounted on the bottom of the door rails. These sensors are designed to cause the door to reverse when something interrupts the light path (like a child) so the object is not squashed. Interestingly, my dog just tripped this one about 10 minutes ago. The door reversed as it was designed and both dog and door are ok. 2) There is an obstruction sensor that detects if there is something that will prevent the door from fully closing. If the door meets resistance as it is closing in other than the full down position it interprets the resistance as an obstruction and reverses motion. So if you inadvertently left a 2x4 laying across the threshold, the door would hit the 2x4 and interpret it as an obstruction and then reverse motion and return to the full up position.

Make sure you have the door installed securely. It's very thin and can appear secure when in fact it's not. Do you remove the cover frequently?

I have found, that if you do not adhere to the clearances in the manual, that the sensor is so sensitive, it will affect the on, off, operation. Also, keeping the filters cleaned pretty much weekly is positively necessary for the same reason. Other than that, it's a hell of a good heater.

There is no sensor, it is on until you turn it off. I usually let mine run al the time.

The two sensors that are on the far right of the unit might be crusted with deposits.I would fill the base full with 1/2 water and 1/2 vinegar (if it's real full it will cover thesensors) or you can chip it off but be careful about damaging the sensor).

I put a small stainless steel plate beside mine and turned down the sensitivity//works great,went off the other night..i looked out,and nobodyon my property,,so I unplugged it,,,,found out in the morning ,,some one ,broke in to the car,next door and cut my locks on my bike trailer,,,but must have left,,because of the barking,,real lat

The sensor is located inside the unit so location is important. I placed mine in the same opening as the original detector. It should be as close to the floor as possible since propane is heavier then air.

the sensor is easy to install. just lead the wire along your dash and the window and out the door onto the the very corner of your window frame at bottom left. It is simply a sticker that you peal off, and once you stick the sensor on, it stays there good. Mine has never moved. you put it there on frame so that if you live in snowing country, it won't remove itself when you broom away the snow. I even do broom over it and has stayed through out first winter. the weather results are pretty accurate.

Yes, you can set the sensitivity to your preference.... In fact, it can be so high that it will go off if someone slams a door in the house!

It manually triggers the sensor. Makes it easier to configure and test the sensor without opening and closing the door.
