Set a 10-second delay to come and go freely while still getting alerts if someone else enters or leaves the door ajar.

Great for baby gates, lab doors, and restricted access areas. Mode B (2 beeps confirmation) — Alerts after 10 seconds, repeats every 15 seconds. Works well for frequently used doors by Kids, pets... Mode D (4 beeps confirmation) — Alerts after 60 seconds, repeats every 30 seconds. Perfect for laundry rooms, basements, and storage areas. Mode E (5 beeps confirmation) — Instant alert, repeats every 5 seconds. Use as an entry chime or for immediate alerts. Mode F (6 beeps confirmation) — Alerts after 2 minutes, repeats every 2 minutes.

Installation Use the bottom-right button to set Zero Delay (Mode E – 5 beeps) and test installation. Keep the triangle markers aligned with a distance of ≤ 1 cm (0.4 in). If the gap is > 1 cm (0.4 in), slightly overhang the door edge (on some fridges or freezers). Mount on a clean, flat surface using the included adhesive. Low Battery When the batteries are running low, the FRIDGGI 3in1 Alarm will emit continuous low beeps, indicating that it's time to replace them. Review: Not obnoxious but effective door alarm - Got this door alarm to alert me that door is open, originally for preventing dog from escaping. Alarm goes off after door open for a few seconds. It is not an obnoxious sound but is a persistent sound alert. Easy to install, sticks with included mastic tape. Can be made inactive easily using the switch. Review: Works just like it says - perfect solution - Last mini fridge had a built in door alarm so we knew when the kids accidentally left it open - moved to a new house, bought a new mini fridge that we thought was exactly the same… nope, no door alarm. This item works like a charm! You can set how long it will wait before alerting you (so it doesn’t go off when you’re just getting a drink or filling the fridge) and how loud it is and it even has a few different tones so you can choose the one you like best.
