Key Features & Benefits
Reliable Multi-Zone Detection
From single-zone basics to 18-zone precision detection, the GHT Classic Series provides clear alarm indication with LED bar displays showing exactly where on the body a detected item is located — reducing unnecessary secondary screening.
Simple Setup & Operation
Both models feature intuitive controls, fast power-on readiness, and minimal calibration requirements. Security staff can operate and manage settings without technical expertise.
Audible & Visual Alarm System
All models feature built-in buzzers and LED indicators for immediate alarm notifications. Configurable alarm sensitivity reduces false alarms caused by common items such as belt buckles, keys, and coins.
Fixed Deployment Ready
Both the GS900B and GS900D are designed for fixed frame installation, making them ideal for permanent entry points at schools, government buildings, courthouses, and corporate facilities.
Detection Zones
GS900B operates as a single detection zone for fast, simple screening. The GS900D supports 6 to 18 selectable detection zones, enabling pinpoint body-zone alarm location to reduce unnecessary secondary screening and speed up throughput.
Power & Installation
Both models operate on AC 110–220V and are designed for fixed frame installation. A standard setup typically takes under two hours with no specialist tools required, making them ready for rapid permanent deployment at any entry point.
Certifications & Compliance
Both the GS900B and GS900D carry CE and ISO certifications, meeting international safety and performance standards. Solid-state electronics and robust frame construction are built for continuous operation with minimal downtime across all deployment environments.

Frequently Asked Questions
What is the difference between GS900B and GS900D?
The GS900B is a single-zone model ideal for basic screening needs, while the GS900D supports 6 to 18 detection zones with a small LCD display, providing more precise alarm location data to target secondary screening efficiently.
Can sensitivity be adjusted to ignore small items like belt buckles?
Yes. Both models support sensitivity adjustment to reduce false alarms triggered by common everyday items such as keys, coins, and belt buckles — allowing security staff to calibrate the detector to their specific deployment environment.
Do these detectors interfere with medical implants such as pacemakers?
The detectors emit low electromagnetic fields compliant with CE standards. However, it is recommended that individuals with pacemakers or metal implants notify security staff prior to screening so that alternative screening procedures can be arranged.
How long does installation take?
Both models are designed for fast fixed installation. A standard setup typically takes under two hours with no specialist tools required, minimising disruption to your facility operations.
