Door Stopper Alarm – 120dB Portable Security Wedge | Idiello

Portable Door Stopper Alarm for Home and Travel

Add a simple, portable layer to your personal-security routine with this 120dB door stopper alarm from Idiello.com. Designed for inward-opening hinged doors with a floor gap between 1cm and 3.5cm, the wedge activates when door movement places pressure on its upper sensor plate.

Its vibration-sensor system, three sensitivity settings and compact design make it suitable for homes, offices, hotel rooms and dormitories. No permanent installation, drilling or wiring is required.

This product is a supplementary alert device. It cannot guarantee that forced entry, theft or other incidents will be prevented.

Key Features of the Door Stopper Alarm

This compact security accessory combines a wedge-shaped door blocker with a loud battery-operated alarm.

Loud 120dB Siren

When the alarm is switched on and correctly positioned, inward door movement presses against the sensor plate and activates the stated 120dB siren.

The loud sound is designed to:

• Alert room occupants
• Draw attention to door movement
• Discourage an unexpected entrant
• Provide time to respond appropriately

Actual perceived volume can vary according to battery condition, room acoustics, flooring and distance from the device.

Vibration and Pressure Activation

The alarm operates through a vibration or pressure-sensitive mechanism. When the door moves against the wedge, pressure on the upper plate triggers the siren.

Correct placement beneath the door is essential for dependable activation.

Three Sensitivity Levels

Choose between three available sensitivity settings:

• High
• Medium
• Low

High sensitivity is intended to respond more readily to vibration. Medium and low settings may be useful in environments where minor movement could otherwise produce unwanted activation.

Test the selected sensitivity after every placement.

Wedge-Shaped Doorstop Design

The tapered body fits beneath a compatible inward-opening hinged door. In addition to supporting the alarm mechanism, its wedge shape helps resist door movement.

Effectiveness depends on:

• Door direction
• Floor surface
• Door weight
• Bottom-door gap
• Wedge placement
• Condition of the non-skid surface

Non-Skid Base

The underside is designed to grip the floor when pressure is applied. For the best contact, place it on a clean, dry and level surface.

Very smooth, wet, dusty or uneven floors may reduce grip.

Alarm and Standard Doorstop Modes

The product provides two practical uses:

• Alarm mode: Switch the power on to activate the siren when the door presses the sensor.
• Doorstop mode: Switch the power off to use it as a standard wedge without the alarm.

It should not be relied upon as a substitute for an approved door lock.

No Permanent Installation

No drilling, screws, adhesive or permanent wiring is required. Simply insert the required battery, select the sensitivity and position the alarm beneath a compatible door.

Compact Travel Design

At approximately 14 × 4.5 × 4cm, the alarm is compact enough for:

• Suitcases
• Backpacks
• Hand luggage
• Office drawers
• Bedside storage
• Emergency kits

Check airline and destination rules before travelling with batteries.

Door Compatibility Requirements

The alarm is designed for doors that meet both of the following conditions:

• The door opens inward towards the protected room
• The gap between the bottom of the door and floor is approximately 1–3.5cm

It may not work correctly with:

• Outward-opening doors
• Sliding doors
• Doors with less than a 1cm gap
• Doors with more than a 3.5cm gap
• Uneven thresholds
• Thick rugs beneath the door
• Wet, dusty or highly slippery floors
• Doors that do not contact the sensor plate

Measure the gap before ordering.

How to Install the Door Stopper Alarm

1. Measure the gap beneath the door.
2. Confirm that the gap is between 1cm and 3.5cm.
3. Check that the door opens inward.
4. Open the battery compartment.
5. Insert the correct battery according to the product markings.
6. Close the battery-compartment cover securely.
7. Place the wedge beneath the inside edge of the closed or nearly closed door.
8. Position the upper plate where door movement will apply pressure.
9. Select high, medium or low sensitivity.
10. Switch on the alarm.
11. Test it carefully before depending on it.

Battery type and inclusion have not been specified in the supplied product information.

How to Test the Alarm Safely

1. Notify everyone nearby before testing.
2. Keep children and animals away from the device.
3. Do not place your ear near the alarm.
4. Stand at a safe distance.
5. Gently move the door against the sensor plate.
6. Confirm that the alarm activates.
7. Switch off or reset the device according to its controls.
8. Reposition it if activation is inconsistent.
9. Repeat the test after changing the sensitivity or moving the alarm.

Because the siren is rated at 120dB, avoid unnecessary or prolonged testing.

How to Use It as a Standard Doorstop

1. Move the power switch to the off position.
2. Place the wedge beneath a compatible inward-opening door.
3. Push it gently into position.
4. Confirm that the non-skid base contacts the floor.
5. Remove it carefully when the door needs to move.

Using it in standard doorstop mode disables the audible alarm.
