Understanding Optex Detection Technologies
Optex detectors are built around three core detection technologies, each suited to different environments and threat profiles. Passive infrared (PIR) sensors detect changes in infrared energy caused by a moving person - they are cost-effective, reliable, and widely used in both indoor and outdoor applications. Dual-technology (PIR + microwave) detectors require both technologies to trigger simultaneously, dramatically reducing false alarms in challenging environments such as industrial sites, areas with HVAC airflow, or locations exposed to direct sunlight. Photoelectric beam detectors use an active infrared beam between a transmitter and receiver - ideal for perimeter protection across driveways, gates, and open boundaries where a physical beam break is the most reliable detection method.
Across all three technologies, Optex incorporates their proprietary CORE Platform digital signal processing, Digital Quad Zone Logic (requiring 4+ detection zones to be crossed before triggering an alarm), and double conductive shielding to block RFI and visible light interference. These features combine to deliver high detection accuracy with low false alarm rates - a critical requirement for Grade 2 and Grade 3 compliant installations.
---Optex Indoor PIR Detectors
Optex indoor PIR detectors are designed for residential and commercial intrusion detection, offering a range of coverage patterns, mounting options, and compliance grades to suit most panel configurations.
OPT-CX-702 - Passive Infrared Indoor Detector
The CX-702 features a unique spherical lens design that allows the installer to switch between wide-angle and long-range detection patterns by simply rotating the lens - no additional hardware required. It includes multi-focus technology, double conductive shielding, temperature compensation, and sealed optics. The CX-702MKII variant adds a twin pyro element, doubling the detection zones for enhanced accuracy. View our product.
OPT-RXC-ST - Pet Friendly Passive Infrared Detector
Built on Optex's proven RX and CX series platform, the RXC-ST uses Digital Quad Zone Logic with 78 dense zones and advanced temperature compensation to maintain reliable detection even as ambient temperatures approach body temperature. Pet immunity is achieved through high-density zone coverage and digital target recognition, making it suitable for Grade 2 residential, commercial, and industrial applications. View our product.
OPT-FX-360 - 360° Ceiling Mount PIR Detector
The FX-360 is a compact ceiling-mount PIR providing a 12m diameter detection area, ideal for lobbies, open-plan offices, and retail spaces. It features a hard spherical lens for precise 360-degree coverage, false alarm protection, and a warm-up indicator. PD6662:2010 compliant at Grade 2. View our product.
OPT-SX-360Z - 360° Ceiling Mount PIR with Zoom Function
The SX-360Z extends the ceiling-mount PIR concept with a patented zoom system that maintains a consistent 18m (60ft) diameter detection area at any ceiling height from 2.4m to 5m (8 to 16ft).

Optex Indoor Dual-Technology (PIR + Microwave) Detectors
Dual-technology detectors require both PIR and microwave channels to trigger simultaneously before generating an alarm. This makes them the preferred choice for high-risk or environmentally challenging indoor locations where false alarms from a single-technology sensor would be unacceptable.
OPT-FMX-DT-X5 - Combination PIR and Microwave Detector
The FMX-DT is an EN50131-2-2 compliant dual-tech detector covering 15m x 15m at 85 degrees wide, with 78 detection zones.

Optex Outdoor PIR Detectors
Optex outdoor PIR detectors are weatherproofed and engineered to handle the environmental variables that cause false alarms in standard indoor sensors - wind, rain, temperature swings, and small animals. IP ratings, SMDA logic, and pet immunity are key differentiators across this range.
OPT-LX-402 - Outdoor Passive Infrared Detector IP54
The LX-402 is a versatile outdoor PIR covering 12m x 15m in standard mode, with a selectable pet alley mode (mounted at 1.2m) that allows animals to pass underneath without triggering an alarm. Day/night functionality, double conductive shielding, three sensitivity levels, and IP54 weatherproofing make it a practical choice for residential and light commercial perimeter, garden, and driveway applications. View our product.
OPT-WXI-ST - 180° Panoramic Outdoor Detector IP55
The WXI-ST provides a 12m, 180-degree field of view with SMDA (Super Multi Dimension Analysis) digital logic for enhanced environmental adaptation. Two independent left and right detection areas make it ideal for triggering CCTV camera presets, allowing the camera to pan to the specific zone where motion was detected. Selectable pulse count reduces false alarms from environmental interference. View our product.
OPT-QXI-ST - Wide Angle Passive Infrared Outdoor Detector
The QXI-ST is a wide-angle outdoor PIR suited to broad perimeter coverage applications. View our product.
OPT-BXS-ST - Outdoor Boundary Detector with Quad PIR Sensors
The BXS-ST (BX Shield) is a curtain outdoor PIR with up to 12m detection range per side, featuring four PIR elements - two on each side. Each side operates completely independently, with adjustable detection distances (2.5m, 3.5m, 6m, 8.5m, or 12m) and sensitivity settings. The dual-beam design on each side (one pointing toward the floor, one pointing away) ensures small to medium animals are ignored while people are reliably detected. Easily connected to fixed dome CCTV cameras for visual alarm confirmation. View our product.
OPT-FTN-ST - Compact Outdoor Curtain PIR
The FTN-ST is a compact hardwired outdoor curtain PIR with switchable lenses providing either 2m or 5m short-range detection - ideal for protecting front doors, windows, and balconies.

The HX-40 is designed for high-mount outdoor applications where standard mounting heights are not achievable, offering PIR or combination detection options to suit the installation environment. View our product.
---Optex Photoelectric Beam Detectors
Photoelectric beam detectors use an active infrared beam between a transmitter and receiver unit. When the beam is broken, an alarm is triggered. This makes them ideal for perimeter protection across open boundaries - driveways, gates, rooflines, and garden perimeters - where a physical beam break is more reliable than PIR motion detection in open outdoor environments.
OPT-SL-200QN - Outdoor 60m Photoelectric Detector IP65
The SL-200QN provides up to 60m (200ft) outdoor detection range with quad beam detection to dramatically reduce false alarms from birds and falling leaves. A Sniper Viewfinder with x2 magnification and an alignment dial simplify installation and optical alignment. IP65 rated. Compatible with the BAU-4 beam alignment unit for single-technician alignment. Applications include perimeter, roof/ceiling, garden, and driveway. View our product.
OPT-SL-650QN - Outdoor 200m Photoelectric Detector IP65
The SL-650QN extends the SL series to 200m (650ft) outdoor detection range, making it suitable for large perimeter applications including industrial sites, warehouses, and open boundary protection. High-grade aspherical lenses, two easy-alignment tools, and IP65-rated UV-resistant polycarbonate housing with frost-prevention hoods ensure reliable long-term performance. Can be connected to an IP network via the optional PIE-1 IP/POE module. View our product.

---Choosing the Right Optex Detector for Your Application
Selecting the correct detector depends on three primary factors: environment (indoor vs. outdoor), required detection technology (PIR, dual-tech, or photoelectric), and compliance grade. For standard residential and light commercial indoor applications, the CX-702, RXC-ST, or FX-360/SX-360Z ceiling models cover most scenarios. Where false alarm immunity is critical - industrial sites, high-traffic areas, or locations with HVAC - the FMX-DT-X5 or CDX-DAM-X5 dual-tech models are the appropriate choice. For outdoor perimeter protection, the LX-402 and WXI-ST handle most residential and commercial boundary applications, while the BXS-ST and FTN-ST address specific curtain detection needs at entry points. Long-range perimeter protection across open boundaries is best served by the SL-200QN or SL-650QN photoelectric beam detectors.
