## Questions & Answers

**Q: Does the remote have to be next to the alarm to switch it off, or can it be on the other side of a door and work?**
A: You can be a short distance away. You activate it while door is closed. Then deactivate it before entering. They are a little extra security and very loud when alarm goes off

**Q: what is the width of the magnet ? My door frame is very narrow.**
A: Thank you for your question.
The alarm host size is 85mm*40mm*15mm.the magnet box size is 50mm*11mm*10mm,the distance between the two screw holes is 40mm.Generally do not need screw installation, use self-adhesive(included) will do.

**Q: Will the alarm stop sounding once the door is closed? Looking to buy something for a fire exit that people keep leaving open.**
A: Thank you for your interest.
Yes, it will stop making the sound when the door is closed. Of course you can turn off the sound at any time with the remote control.

**Q: Do the remote's control multiple alarms or is it only one remote for each alarm? If I was to order 3/4 pack could all remotes be linked to all alarms?**
A: No they can’t be linked. It’s a kit with the door magnets and the remote as a set.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great little addition for peace of mind.
*by A***N on 31 July 2025*

Had these on about a year now and really impressed, they are SO loud! We use them on our front and back door for extra peace of mind. Easy enough to put on and they've stayed on for a year and still going strong. Really impressed and definitely recommend for extra precaution, especailly becasue we have pets so we can't turn our alarm on at night so this is just nice to have and we know it will wake us up!
