9V Battery Powered 360 Degree Human Body Induction Anti-Theft Alarm Door Handle Contact Induction Touch Alarm for Wooden Door Metal Lock Black
9V Human Body Induction Anti-Theft Alarm with 360-Degree Contact Detection for Wooden Doors

This anti-theft alarm offers a straightforward solution for securing entry points by detecting human contact with door handles or locks. Operating on a 9V battery, it triggers a 100mA alarm current when a person touches the handle, providing an immediate audible deterrent. The 360-degree detection angle covers a full surround area up to 0.1 metres, making it suitable for narrow door spaces. Designed specifically for wooden doors with metal locks, this alarm installs via a simple hanging method without drilling or wiring. The model 902 door handle black finish blends discreetly with most door hardware.
Features and Construction

The alarm combines basic electronic detection with easy installation for practical home security use. Its compact housing contains the necessary circuitry to sense human body induction through contact.
Material and Build
The unit is constructed from standard plastic and metal components common to budget alarm devices. It includes metal contact points that connect to the door handle or lock to complete the detection circuit. The black finish helps it remain unobtrusive when hung on a door.
Size and Practical Fit
The alarm has a detection distance of 0.1 metres (approximately 10 centimetres), meaning it activates only when someone physically touches or comes very close to the handle. This focused range reduces false alarms from passing movement or pets while ensuring the door itself remains protected.
Uses and Placement

This alarm is intended for use on wooden doors fitted with metal locks, where hanging installation is possible. Its compact design makes it suitable for internal doors, storage rooms, or as a supplementary alert on main entrances.
Event or Professional Use
For temporary setups such as event rooms, exhibition stands, or rented spaces, the hanging installation allows quick deployment and removal without damaging surfaces. The 9V battery operation means no mains power is required, adding flexibility for portable use.
Everyday Home Use
At home, the alarm can be placed on a back door, garage entrance, or workshop door to alert occupants when someone attempts to open or touch the handle. The 360-degree detection ensures the alarm is not directional, so it works regardless of which side the handle is approached from.
Benefits and Buying Value

This device offers a basic but functional security layer for doors that lack built-in alarms. Its simple installation and contact sensing provide peace of mind without complex wiring or smart home integration.
Reuse and Low Maintenance
Once installed, the alarm requires minimal maintenance—only periodic battery changes when the sound output declines. The unit can be moved between doors as needed, making it a reusable security accessory. No software updates or app pairing is required.
Why Choose This Product
For users needing an affordable, no-fuss alarm that activates on physical contact with a door handle, this model delivers the core function without unnecessary features. The 360-degree detection and hanging installation make it easy to deploy in multiple locations, while the 9V battery keeps operation independent of power outlets.
