Door Stop Alarm — Loud Intruder Deterrent

If that door opens at 3am, you'll know before they're inside.

A lock can be picked. A keycard can be copied. But nobody gets past a 120-decibel siren without waking you — and everyone else on the floor.

This wedge does two jobs at once: it physically blocks the door from swinging open, and the moment pressure hits it, it screams. Pair it with your portable door lock and the door is blocked, jammed, and alarmed — three layers, ten seconds of setup.

Why travelers pack it

• 120dB alarm — roughly as loud as a siren, triggered by pressure on the door
• Physical wedge — anti-slip base grips the floor and resists the door opening
• Adjustable sensitivity — set how much pressure triggers the siren
• Zero installation — drop it behind the door, flip the switch, done
• Works anywhere — hotels, Airbnbs, dorms, apartments, ground-floor rooms

How it works

1. Slide the wedge behind the closed door, alarm side up.
2. Flip the arm switch.
3. If the door opens against it, the siren fires instantly.

FAQ

Will it work on carpet? Yes — the anti-slip base grips carpet and hard floors; it wedges tighter as the door pushes.
What battery does it take? A standard 9V battery, not included — available at any grocery or convenience store.
Can I use it without the alarm? Yes, switch off and it's a regular door stop.
How loud is 120dB? About as loud as an ambulance siren — you will not sleep through it, and neither will they.
