The GJD D‑TECT 50 (GJD350) is a long‑range external quad‑element PIR motion detector engineered for perimeter and large‑area protection. It provides a narrow, programmable detection beam (25–50 m) with advanced signal processing and custom optics to reduce boundary overspill. The robust zinc‑alloy housing (IP55) and conformally coated electronics make it suitable for exposed outdoor installations.

• Programmable detection range: 25–50 m for perimeter runs and long approach detection.
• Narrow, long‑range beam with quad‑element PIR and 12 detection zones per pyro pair.
• Coverage up to 50 × 10 m; optimum mounting height ≈ 3 m; 180° pan and 90° tilt for precise aiming.
• 2 × volt‑free solid‑state alarm outputs, front & rear tamper, configurable light sensing (dusk–24h) and timer (2–60 s).
• Wide input: 9–24 VAC/DC; low current draw (~12 mA at 12 V). Durable zinc‑alloy construction, IP55 rated.

Use cases: ideal for perimeter fencing, industrial perimeters, warehouses and large external areas where a long‑range, narrow detection beam is required. Suitable for professional installation; integrates with wired intruder alarm systems via volt‑free outputs.

Installation & safety: mount at the recommended height (~3 m), use the adjustable pan/tilt for accurate alignment and follow GJD installation guidelines and wiring best practice. Do not attempt installation without isolating supply; use a qualified installer for mains wiring and system integration.

Compliance: check with your supplier for current CE / UKCA conformity and the latest datasheet before installation. Accessories (conduit adaptor GJD304, D‑Guard GJD308, walk tester GJD380, PMB1 pole bracket) available separately.
