Overview
The PB-100FA is a long-range quad (4‑beam) outdoor photoelectric perimeter sensor designed for reliable perimeter intrusion detection to 100 m (330 ft). The PB‑FA series uses synchronised beams (AND gating), double‑modulation and auto‑gain circuitry to reduce nuisance alarms from small animals, debris and strong light sources.

• Quad synchronised infrared beams with AND gating for improved false alarm resistance.
• Double‑modulation and phase‑locked loop tuning amplifier for high light immunity (50,000 lux tolerance).
• Auto‑gain control (AGC) and auto‑gain lock, audible alignment tone and monitor jack for setup.
• Protection distance: 100 m (330 ft) outdoor. Wide beam alignment: ±90° horizontal, ±10° vertical.
• Power: 12–30 V DC (non‑polarity). Dry‑contact alarm (selectable NO/NC) and tamper outputs.
• Weatherproof IP55 enclosure with polycarbonate cover; suitable for outdoor installation.

Use cases: perimeter security for commercial sites, warehouses, utilities and other outdoor perimeters where reliable long‑range detection and low nuisance alarm rates are required. Suitable for installers and systems integrators; typically supplied as transmitter/receiver pairs and mounted on posts or walls.

Installation & safety: Installation should be performed by a qualified technician to ensure correct alignment, wiring and compliance with local regulations. Observe recommended mounting heights and alignment procedures in the manufacturer datasheet. Power wiring must respect local electrical codes.

Certifications / Notes: Manufacturer datasheet is the authoritative source for full specifications and available variants. Certifications (CE/UKCA) and included accessories vary by region and SKU: INSUFFICIENT DATA.
