Door Stopper Alarm – 120dB Portable Security Wedge | Idiello

Portable Door Stopper Alarm for Home and Travel

Add a portable audible alert to your home or travel security setup with this 120dB door stopper alarm from Idiello.com. Designed for compatible inward-opening hinged doors with an approximately 1–3.5cm gap beneath them, the wedge activates its alarm when door movement applies pressure to the upper sensor plate.

The battery-operated design offers three sensitivity settings and requires no drilling, permanent wiring or fixed installation. Its compact size makes it suitable for homes, offices, hotel rooms, dormitories and travel.

Important: This product is a supplementary alert device. It is not a replacement for a proper door lock and cannot guarantee prevention of forced entry, theft or other security incidents.

Key Features of the Door Stopper Alarm

This compact security accessory combines a wedge-shaped doorstop with a battery-operated audible alarm.

Stated 120dB Alarm

When the alarm is switched on and correctly positioned, movement of a compatible inward-opening door applies pressure to the sensor plate and activates the stated 120dB alarm.

The audible alert is designed to:

• Alert occupants to door movement
• Draw attention to activity at the door
• Provide an audible warning
• Allow occupants to respond appropriately

Actual perceived volume can vary depending on room acoustics, distance, battery condition and surrounding conditions.

Vibration and Pressure Activation

The alarm uses a vibration and pressure-sensitive activation mechanism.

When an inward-opening door moves against the wedge and applies sufficient pressure to the upper plate, the alarm is triggered.

Correct positioning is important. Test the device after every placement before relying on its alert function.

Three Sensitivity Levels

The door alarm provides three sensitivity settings:

• High
• Medium
• Low

High sensitivity is intended to respond more readily to movement or vibration, while lower settings may help reduce unwanted activation in some environments.

Test the selected setting after positioning the alarm.

Wedge-Shaped Doorstop Design

The tapered body is designed to sit beneath a compatible inward-opening hinged door.

Its wedge shape can also help resist door movement when correctly positioned.

Performance can depend on factors including:

• Door direction
• Floor surface
• Door weight
• Gap beneath the door
• Device positioning
• Contact between the base and floor

The product should not be treated as a replacement for a proper locking system.

Non-Skid Base

The wedge features a non-skid base designed to maintain contact with the floor when pressure is applied.

For suitable placement, use the alarm on a clean, dry and level surface.

Wet, dusty, uneven or particularly slippery flooring may reduce grip.

Alarm and Doorstop Modes

The product can be used in two ways:

Alarm Mode: Switch the device on and position it beneath a compatible door so movement against the sensor can activate the audible alarm.

Doorstop Mode: Switch the alarm off and use the wedge as a standard doorstop.

Using the device with the power switched off disables the audible alarm function.

No Permanent Installation Required

The portable alarm does not require:

• Drilling
• Screws
• Adhesive installation
• Permanent wiring

Insert the appropriate battery, select the required sensitivity level and position the device beneath a compatible door.

Compact Travel Design

At approximately 14 × 4.5 × 4cm, the door stopper alarm is compact enough for storage in:

• Suitcases
• Backpacks
• Hand luggage
• Office drawers
• Bedside storage
• Travel-security kits

When travelling with batteries, check applicable airline and destination requirements.

2. Keep children and animals away from the alarm.
3. Keep your ears away from the speaker.
4. Stand at an appropriate distance.
5. Gently move the door against the sensor plate.
6. Confirm that the alarm activates.

Avoid unnecessary or prolonged alarm activation.

How to Use It as a Standard Doorstop
