Need an alarm to sound when the front door is left open

[jp1986]

Hi

A few times now I've got home to my flat and found the door slightly ajar because my boyfriend has come home a few hours earlier and left it open behind him. I am really concerned about this and am desperately trying to find an alarm that sounds when it is left open for too long. I've seen lots of burglar alarms that sound as soon as the door is opened, or even ones where you can set a time delay, but these you also have to arm whenever you go out and come back which I don't want.

Does anybody have anything like this in their home?

why not just tell boyfriend to grow up? What an idiot.

I'm not sure how an alarm would help if you are out. It would surely alert other people to the fact that your door is open.

Tell your bf not to be a dick. And take his key away so he can't pop round.

i think lemon is right. others would come to know that the alarm means the door is open. it would also be bad because if your boyfriend is actually home potential burglars would come and think the house is empty and there could be an unexpected dangerous confrontation

The alarm would sound, he would hear it and quickly close the door.

It would work in the same way that modern fridges/freezers sound an alarm when the door is left open too long...

How about a self-closing front door?

But why doesn't he just check he has shut it properly

Do you mean that the alarm would go off when your boyfriend left the flat?

So hearing it would prompt him to close the door?

You do get Contact Alarms for doors and windows that sound an alarm/siren when the contact is broken.

I don't have any to recommend but have seen them somewhere. I don't think they're expensive iirc.

so maybe Google contact door alarms.

These are cheap, and don't need to be set, but will sound every time - for as long as - the door is open. I don't think there's a delay setting.

you could secure a personal attack alarm to the door, with the the pin attached to the frame. When the door is opened the pin will be pulled out and it will make a very loud sound which will only cease when he closes the door and puts the pin back in. it will be annoying that it happens every time he comes home but then you can take it away and tell him if he goes back to bad habits you will reinstate the alarm.

at some of the responses. I don't think it's a daft suggestion at all and I have looked for something similar in the past to alert me if the garage door gets left open. Obviously it's a bit stupid of someone if they do but it's better to be safe. My fridge warns me if its left open and my car warns me if leave the lights on, it's the same thing surely

your fridge and your car have in built electrical circuits and it is easy to add this functionality.

your front door does not. Your boyfriend should have some electrical activity between his ears. Why is this so difficult?

Is this during the day and he is in the house?

Surely if he's present and awake then he is risking only himself getting into a confrontation situation by doing this. Maybe he likes living on the edge.But if hes an adult surely he knows he needs to ensure the house is safe himself rather than rely on technology .

If you want to teach him a lesson though sneak in through the open door and take something precious he has left lying around. He'll learn fast enough if his actions cost him money.

It is possible, in the USA]. I think strain ng the boyfriend would be better, as an alarm when out could be problematic.

Or, could you add a door closer so it automatically shuts behind everyone?
