Make a Quiet Opening Hard to Miss
Give a door or window its own audible alert, with a response you can choose for the way you use it.
For the Door or Window You Check Twice
Start with the entry you pay the most attention to, whether that’s the door to your apartment or a window in a quiet room. The battery-powered unit works without wiring or a hub.
A simple way to give one entry point a voice.
Mount, Align, and Test
Close the door or window first so you can see how the two pieces will sit.
-
Prep the Surfaces
Clean and dry the spots where the alarm and magnet will sit.
-
Match the Markers
Line up the triangular marks and check that the gap is within 10 mm when closed.
-
Secure Both Pieces
Use the supplied 3M adhesive to mount the alarm and magnet in their aligned positions.
-
Try an Opening
Turn the unit on, select an opening-response mode, then open the door or window to check the sound.
What the Sensors Pick Up
The alarm can respond to movement at the entry and to vibration while it’s still closed.
Opening Detection
The magnetic sensor detects when the alarm and magnet separate.
Vibration Detection
The vibration sensor responds to impacts when vibration detection is active.
Combined Detection
A combined setting lets either type of activity trigger a response.
High-Pitched Alarm
The alarm can reach up to 130 dB when triggered.
Three Ways to Use the Alert
Choose the event you want to hear at the spot you’ve set up.
Hear Regular Coming and Going
Set a chime on a patio door that opens often during the day.
Listen for an Overnight Opening
Use an opening alarm on a window you plan to keep closed overnight.
Listen for a Knock or Impact
Choose vibration-only warning when you want an alert for vibration at a closed entry.
Set It Up the Way You’ll Use It
Make adjustments at the alarm itself.

💡
Physical ON/OFF Slider
Check the slider position at a glance before leaving the room.
Set It When You Need It
Build the alarm into a routine you already have.
During the Evening Check
After closing the bedroom window for the night, turn the alarm on while you’re still at the frame.
While You’re Using the Patio
Switch the unit off while you’re making trips in and out, then turn it back on once the door is closed for the evening.
Three Places to Start
Pick the opening that matters most in the space you’re setting up.
A New Apartment
Start with the door you’ll use every day as you get settled.
An Off-Campus Rental
Set up an alert at the bedroom window during move-in.
A Room You’re Putting Back to Use
Check the window frame for a mounting spot as you get the room ready.
Check the Frame and the Listening Spot
Look at the opening itself, then consider where you’ll usually be when it’s in use.
Check the Mounting Layout
Look for two spots that line up when closed. The magnet can sit on either side of the main unit.
Think About Where You’ll Hear It
Choose an entry close enough to your usual spot for a local sound to be useful, then listen from there during your test.
For Everyday Entry Awareness
Consider what you need from the alert and how you’d like to control it.
Renters Avoiding Drill Holes
Use adhesive where the alarm and magnet can line up on your door or window.
Households With a Busy Patio Door
Give a frequently used entry an audible cue while you’re nearby.
People Who Prefer Physical Controls
Switch the unit on or off and select a mode at the door or window.
Rooms Beyond Reliable Wi-Fi
The local alert works independently of your wireless network.

Before You Mount It
Do I need an app to set it up?
The physical controls handle power and mode selection, and the unit sounds its alerts locally.
Can it react while the door is still closed?
Yes. With vibration detection active, an impact can trigger a warning while the magnet and main unit are still aligned.
Can I set it to chime when the door opens?
Yes. Select the chime option for a door you want to hear during ordinary use.
What if the magnet fits better on the left?
Either side works. Align the triangular marks on the side you choose and check the gap with the door closed.
Do volume and sensitivity change the same thing?
Volume changes how loud the alert sounds. Vibration sensitivity changes how readily vibration triggers it.
What should I check if opening the window makes no sound?
Check that the unit is on, the selected mode responds to opening, and the pieces line up within 10 mm when the window is closed. Then test it again.
Start With One Door or Window
Pick the opening you’d like to hear, check the mounting space, and choose a response that suits how you use it.
