Overview

The FX-40 Series Passive Infrared (PIR) Detectors by OPTEX are designed for residential, commercial, and light industrial security applications. They detect intruder movement and activate alarm control panels as part of a complete security system. The product complies with EMC Directive 89/336 EEC and emphasizes reliability, ease of installation, and environmental compensation.

Detection Patterns and Coverage

• Wide Angle Models (FX-40, FX-40D): Coverage of 12m x 12m (40ft x 40ft) with 85° wide angle and 72 detection zones.
• Long Range Models (FX-40L, FX-40DL): Coverage of 18m x 1.8m (60ft x 6ft) with 20 detection zones, designed for extremely dense multi-layer curtain detection.
• Optional Lens (FL-60N): Enhances long-range detection with a dense multi-layer curtain pattern.

Key Specifications

Design and Technology Features

• Multi-Focus Optics and Spherical Lens Design: Provides high vertical zone density (2-3 times conventional PIRs), capturing full body mass and minimizing dead zones caused by furniture or partitions.
• Temperature Compensation Circuit: Automatically adjusts sensitivity to maintain detection accuracy and reduce false alarms in high temperature environments where background temperature is close to human body temperature.
• Double Conductive Shielding: Protects the pyroelectric element from radio frequency interference (RFI) and visible light, reducing false alarms from external electromagnetic sources and sunlight reflections.
• Sealed Optics and Pyroelectric Element: Prevents false alarms caused by drafts and small insects by sealing the pyro element within the housing molding.
• Durability: Spherical lens design offers superior shock resistance compared to flat Fresnel lenses. The PC board is protected by a dedicated wall to prevent damage during installation.

Installation and User Features

• Easy wiring knockouts and wide wiring space facilitate installation.
• Selectable pulse count (2 or 4) to adjust detection sensitivity.
• LED indicator with on/off switch for alarm status visibility.
• Tamper switch to detect cover removal (models FX-40/40L/40D/40DL).
• Selectable alarm memory polarity (positive or negative) on FX-40L/40DL models.
• Wall and ceiling mount bracket with horizontal adjustment of 45° and vertical adjustment from 0° to 15° downward.

Performance and Reliability

• False alarm protection against RFI up to 20-30V/m and temperature changes from 20°C to 50°C.
• High immunity to environmental disturbances through OPTEX's ECO technology, which discriminates and adjusts for temperature changes and reduces false alarms.
• Reliable detection maintained even in high temperature or low contrast environments.

Dimensions and Accessories

• Compact dimensions approximately 66mm x 46mm x 112mm (2.60" x 1.81" x 4.41").
• Weight around 90g (3.2 oz).
• Accessories include two mounting screws.

Compliance and Certifications

• Conforms to EMC Directive 89/336 EEC for residential, commercial, and light industry use.
• ISO 9001 and ISO 14001 certifications for manufacturing quality and environmental management.
• Listed models: FX-40VdS (G196623), FX-45VdS (G196625).
