Overview
The GJD D-TECT 60 (GJD320) is a long-range wired external motion detector using dual‑pyro (dual PIR) technology and custom optics to deliver a long, narrow detection beam for reliable perimeter protection. The unit is housed in a robust zinc‑alloy IP65 enclosure and is manufacturer‑stated BS8418‑compliant.

• Dual PIR (dual‑pyro) sensors for improved detection and false‑alarm resistance.
• Programmable detection range: 40 m or 60 m for flexible perimeter coverage.
• Detection coverage up to 60 m × 6 m (long, narrow beam).
• Alignment adjustment: 180° pan and 90° tilt for precise beam aiming.
• Volt‑free silent solid‑state outputs, tamper switch and engineer‑friendly walk‑test mode.
• Robust zinc‑alloy housing rated to IP65 for outdoor use; operating −20 °C to +55 °C.

Use cases
Designed for perimeter detection on commercial and high‑security sites where long, narrow beam coverage is required. Suitable for contractors and installers requiring engineer features such as walk‑test, easy cable termination and alignment. Installation should follow the official manual and local wiring regulations; recommended mounting height is approximately 2.6–3.0 m.

Compliance & safety
Manufacturer states BS8418 compliance. Installers should verify local compliance (CE/UKCA where applicable) and follow the supplied installation manual for EMC, cable runs and safe working practices.
