SKU#: 100US-0001
  • Motion Sensor Function: Equipped with an advanced pressure sensor technology. Simply place the alarm behind any door and, when opened, the pressure on the doorstopper will activate the +90db Alarm.
  • Compatible with all 1byone alarm receivers: The door stopper can be configured to send out signals to a distant receiver.
  • On/off switch to toggle activation: The on/off switch will prevent the alarm from accidental sounding.
  • Low-battery indicator light: Light indicator flashes if the battery is low. Without batteries it can also work as a wedge to prevent the door from opening or closing.
  • Battery powered: No wiring or complicated installation. Requires only 3x 1.5V AAA batteries (not included).

Setting up the door stopper alarm is as easy as sliding the power switch to the "On" position and placing the alarm at the foot of the door you want to monitor. If an intruder attempts to open the door, the wedge -shaped design will prevent it from opening and activate an above 90dB alarm. The alarm will scare off would-be intruders and alert you at the same time. With secure gripping ability, the alarm can function as a door stopper that prevents a door from being opened.

Dual Function: Alarm & Door Stopper.

This product is designed as a simple door stopper but can also function as an alarm system.

Keeps Intruders Out.

The +90dB alarm will sound for 2 seconds and repeats itself three times. Any sneaking intruder should be effectively shocked!

No Installation Required.

The easiest setup ever. Add batteries (3x 1.5V AAA, not included) and switch on the door stopper. Done!

Usable Anywhere!

Main door, your college dorm, your office; this door stopper can hold any door or secure passage through the door. All you need is a general door in its common habitat.


The LED indicator silently warns you when the battery is nearly drained. The flashing LED will remind you once the battery is running low.

Can you program the transmitters so they won't conflict with the other units in the apartment building

If they have a similar model you might have an issue. If not you should be fine. I am next to other offices with door bells and nothing happens. I can check later today if it is programmable.

Can you purchase additional transmitters - we need 2....

My thought would be yes in theory but if the supplier will only sell the complete units then you may be out of luck.

If the alarm is activated by someone pushing the door in and you are not home, does it keep sounding off or is there a time limit?

Yes the sound would Continue,until you turn off the button. It would be better if the door close back it would stop it the sound by itself,but it does not. I don't know if I just happen to get a defective one that I have to return m Mine.
