Re: Keyless entry for residential property?
I have plenty of objects in my house that are battery powered, my smoke alarm iirc is wired into the mains with battery backup, same with the CO2 detector, by my front door is a set of double doors leading into a tiny closet where the fuse box is contained, a fuse box which is designed that in case of fire it will contain it as long as possible. As well as the double doors giving secondary protection against a fire on the fuse box.
In the passage way leading to the front door there is a light switch and a light (naturally) and nothing else. If there was an object on my front door which could catch fire, the door itself is made of metal so is again, designed to prevent the spread of fire quickly.
If my 18650 battery was to catch fire then they would catch fire in an area where I could say "oh dear, a fire, I best go through the front door and smash the fire alarm button to warn everyone", if my electronic lock caught fire then the fire would be, you know, at the fire escape. In fact, if anything in my house was to catch fire I would be able to escape through the front door, except in the case of the front door being on fire.
Not really sure what part of "best not to put something which could catch fire infront of the fire escape" went over your head, was it that you have no spatial awareness so are unable to comprehend that having a fire in the kitchen is very different to having a fire at the point of egress? Heck, I could even quote the old adverts "get out, get the fire brigade out, stay out", the "get out" part is really important here, you get out via the part thats currently on fire because of a fault in an electronic item which is attached to the object you use to escape in case of a fire.
I could go on all night with with this, I really didn't think I would have to explain to a reader on this site the potential danger from a fire at the fire escape.
Oh, and if my smoke detector caught fire, I would leave through the fire escape as the second smoke detector would start making a horrible noise.
