## Questions & Answers

**Q: Will they work on double glazed conservatory doors**
A: Assuming you have an ERA Wireless Alarm system, I don't see why not in principle. I have a bit of a problem on the french doors in my lounge as they have rather large bevelled edges where they join and this means that in order for both parts to be close enough, the narrower part has to sit on the bevelled edge and the wider part has to protrude from the flat surface of the opposite door making it potentially vunerable to being torn off the door when the doors are partially open.

**Q: Are you able to use screws to fit this**
A: Yes, I did use small screws to fit some and the self adhesive pads for others.  Screw holes are there, no modifications required.

**Q: Does this work with the older Miguard AV1 alarm system?**
A: Don't Know. Mine is working with a ERA Home Guard Pro

**Q: Hi, will these work with a different wireless system? E.G Cürv**
A: No only work with the ERA home guard systems
