01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Loud, simple security for every doorway
This unassuming black device sits quietly on your window frame or refrigerator handle, a discreet sentinel that only speaks when needed. It transforms an open gap into a clear signal, keeping your space orderly without the clutter of complex wiring.
Designed for homes, offices and garages, it alerts you to an ajar door or an open medicine cabinet. The loud chime ensures no one leaves unnoticed, making it ideal for families, travellers or anyone who values a well-kept environment.


02SOUND
A voice that commands attention
At 130 decibels, this alarm is engineered to be heard over traffic, appliances and conversation. Whether set to an immediate burst or a rhythmic Di-Di pattern, the sound is sharp and distinct. It does not merely whisper; it announces, ensuring that an open door in a busy house or a quiet study is impossible to miss.

04INSTALLATION
Tape it on, no tools required
Setup requires no drilling, screws or electrical work. Simply peel the backing off the double-sided tape and press the sensor onto a flat surface. The magnetic nature of the sensor means it adheres securely to wood, metal or glass. This frictionless installation makes it perfect for renters or those who prefer a minimalist approach to home security.
SENSING
Precision in the smallest gap
The dual-sided magnetic sensor detects separation from just 0.59 inches away. This sensitivity ensures that even a slightly cracked window or a loosely closed cupboard triggers the alert. Unlike single-side sensors, this design works effectively on flat doors and frames, providing reliable coverage for windows, refrigerators and storage boxes alike.
