💡 How does a normally closed magnetic detector improve wired home security networks?
- Standard alarm control boards rely on closed loops to verify panel integrity across every entry point
- Separating the magnet from the receiver instantly cuts current flow to send a verified breach alert
- Low voltage tolerance matches commercial and residential circuits without damaging sensitive transceivers
- Hidden wall mounts save surface mounting hassle while surviving daily traffic in busy corridors
