Human Body Induction Door Handle Alarm 9V 360 Degree Anti-Theft Security Device Black

This anti-theft alarm is designed for straightforward installation on wooden doors with metal locks, providing a practical deterrent against unauthorised access. Operating at 9V, it uses human body induction to detect movement within 0.1 metres and triggers a 100mA alarm current for a clear alert. The 360-degree detection angle means no approach direction is missed, making it a useful addition to home or office security. With its hanging installation method, it can be placed on existing door handles without permanent fixtures, and the black finish of model 902 ensures it blends with most door hardware.

Features and Construction

This alarm offers a focused set of features for basic perimeter security. Its construction is simple and functional, relying on reliable electronic components for daily use.

Detection and Triggering

The alarm employs human body induction to sense nearby movement at a distance of 0.1 metres. Once triggered, it activates a 100mA alarm current, providing a loud enough sound to deter casual intrusion. The 360-degree coverage ensures that someone approaching from any side will be detected.

Power and Operation

Powered by a 9V battery (not included), the alarm maintains a simple one-switch operation. There are no wires or complex settings; once installed, it is ready to use. The low power draw means the battery should last for several weeks under normal use.

Uses and Placement

This alarm is intended for residential or light commercial security. Its compact size and hanging design make it versatile for various door types that have a metal lock and a wooden door surface.

Home Door Security

Place the alarm on the internal handle of a front door, back door, or hallway door that leads to a private area. It provides an immediate alert if someone approaches the door from inside or outside, giving you time to respond.

Office or Workshop Use

In a professional environment, this alarm can be used on doors to storage rooms, tool sheds, or filing areas. The 360-degree detection and simple installation make it a no-fuss security addition that does not require professional fitting.

Benefits and Buying Value

This product offers a straightforward way to improve security on existing doors without drilling or wiring. Its practical design focuses on ease of use and reliable detection.

Simple Installation and Reusability

The hanging installation means you can move the alarm from one door to another as needed. There is no permanent mounting, so it remains fully reusable if you relocate. This flexibility adds practical value for tenants or those who prefer non-permanent solutions.

Consistent Alert Performance

With the 100mA alarm current and 360-degree sensor, the alarm delivers repeatable response to human approach. The 9V battery is widely available, making replacement straightforward. This maintains the device's usefulness over time without specialised maintenance.
