How it works

🔊 Sound modes

Pick from four volume profiles to suit kitchens, garages, or basements.

🧰 Quick install
  1. Power on and pair with the mini sensor.
  2. Dry-fit, align level, keep a small gap between parts.
  3. Peel, stick, and test by opening/closing the door.

FAQ

How loud is it?

Loud enough to notice from another room (select the mode that fits your space).

Does it beep immediately?

You’ll hear a tiny confirmation beep on open; reminders follow if left open.

What about low battery?

Soft beeps indicate it’s time to replace the LR44 cells.

Where to place the sensor?

Align the alarm and mini sensor level with a small gap for reliable detection.
