GJD D-TECT 3 (GJD310) is a wired, triple-technology external motion detector for perimeter and external intruder detection. Combining a quad-element PIR module, microwave sensor and advanced optics/signal processing, it offers reliable detection up to a programmable 30 m range while reducing false alarms. Housed in a robust zinc-alloy enclosure with front and rear tamper switches, the unit provides multiple outputs for alarm panels, cameras and lighting controllers.

• Triple-tech sensing: quad-element PIR + microwave for reliable detection and false-alarm reduction.
• Programmable detection range: up to 30 m (coverage approx. 30 m × 30 m).
• Multiple outputs: 2 × volt-free and 2 × negative-switched outputs plus common tamper.
• Engineer-friendly: selectable pulse count, timer options, walk-test LEDs and EOL resistor selection.
• Adjustable optics: pan (~180°) and tilt (~90°) for precise alignment.
• Robust construction: zinc-alloy metal housing suitable for external installation.

Use cases: perimeter protection, external intruder detection, CCTV/lighting integration, commercial and high-security domestic installations. Suitable for use by installers and security professionals; also appropriate for end-customer retail when installed by qualified personnel.

Safety & compliance: Follow the manufacturer datasheet and installation instructions for safe and correct wiring. Check the official datasheet for exact regulatory approvals (CE / UKCA) and regional microwave frequency variants prior to installation.
