Overview

The FX-40 Series Passive Infrared (PIR) Detectors by OPTEX are designed for residential, commercial, and light industrial intrusion detection. They detect intruder movement and activate an alarm control panel as part of a complete security system. The product complies with EMC Directive 89/336 EEC.

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, featuring an optional FL-60N lens for extremely dense multi-layer curtain detection.

Key Specifications

• Detection Method: Passive infrared.
• Mounting Height: Normal range 1.5m to 2.4m (5 to 8 ft).
• Sensitivity: Detects temperature difference of 1.6°C at 0.6 m/sec (3°F at 2 ft/sec).
• Detectable Speed: 0.3 to 1.5 m/sec (1 to 5 ft/sec).
• Alarm Output: Normally closed (N.C.), 28V DC max 0.2A.
• Power Supply: 9.5 to 16V DC.
• Current Consumption: Max 17mA (FX-40/40D), 18mA normal and 25mA max (FX-40L/40DL).
• Operating Temperature: 20°C to 50°C (4°F to 122°F).
• Operating Humidity: Up to 95% max.
• RF Interference Immunity: No alarm at 20V/m (FX-40/40L) and 30V/m (FX-40D/40DL) from 100MHz to 1GHz.

Design and Technology Features

• Multi-Focus Optics and Spherical Lens Design: Provides high vertical zone density, capturing entire body mass for precise detection even in low contrast or high temperature environments.
• Temperature Compensation Circuit: Automatically adjusts sensitivity to maintain detection accuracy and reduce false alarms in varying temperature conditions.
• Double Conductive Shielding: Protects the pyroelectric element from radio frequency interference (RFI) and visible light, enhancing false alarm immunity.
• Sealed Optics and Pyroelectric Element: Prevents false alarms caused by drafts or small insects.
• Durability: Hard spherical lens and PC board protection wall improve shock resistance and prevent damage during installation.

Installation and User Features

• Easy wiring knockouts and wide wiring space facilitate installation.
• Selectable pulse count (2 or 4) and LED on/off switch for alarm indication.
• Tamper switch included (FX-40/40L/40D/40DL) to detect cover removal.
• Alarm memory polarity selectable (positive or negative) on FX-40L/40DL models.
• Wall and ceiling mount bracket with horizontal and vertical angle adjustments.

Environmental and Reliability Considerations

• Designed to minimize false alarms from environmental disturbances such as temperature changes, RFI, drafts, and insects.
• Complies with EMC standards for residential and commercial use.
• ISO 9001 and ISO 14001 certified manufacturing.

Accessories and Options

• Two mounting screws included.
• Optional FL-60N lens available for long-range extremely dense multi-layer curtain detection (sold in packs of 5).

Summary

The OPTEX FX-40 Series PIR detectors combine advanced optical technology, environmental compensation, and robust design to provide reliable intrusion detection with minimal false alarms. Their flexible installation features and compliance with industry standards make them suitable for a wide range of security applications.
