Optex FTN-RAMI Wireless Pir Curtain Anti-masking Sensor

Product Description

The OPTEX FTN-RAMI is a wireless passive infrared curtain sensor with integrated anti-masking detection, designed for indoor wall-mount security applications. This unit functions as a terminal node in a wireless PIR sensor network, generating a narrow curtain-style detection zone suited for doorways, windows, and perimeter entry points. The anti-masking feature alerts the system when the sensor face is deliberately obstructed or blocked, a critical capability in commercial and high-security residential installations. Security technicians and licensed alarm installers are the primary trades that specify and deploy this device.

The FTN-RAMI is intended for indoor wall-mount installations where a curtain-pattern detection zone is required rather than a broad wide-angle field. Typical applications include retail entryways, corridors, server rooms, and interior perimeter zones in commercial buildings. As a wireless terminal unit, it communicates back to a compatible OPTEX receiver or panel hub, eliminating the need to run detection wiring through finished walls. This makes it well suited for retrofit security upgrades in existing structures.

Key Features

• Curtain-pattern PIR detection zone for precise coverage of doorways and window openings
• Integrated anti-masking detection alerts the panel when the sensor lens is blocked or obstructed
• Wireless terminal design eliminates detection wiring runs in finished or retrofit installations
• Indoor wall-mount form factor for clean, low-profile deployment
• Sold individually as a single unit

Compatibility

Designed for use within compatible OPTEX wireless PIR sensor systems requiring a curtain-pattern terminal node with anti-masking capability. Consult the OPTEX system documentation to confirm receiver and hub compatibility before installation.

Installation Notes

Installation should be performed by a licensed alarm or low-voltage security technician in accordance with applicable local codes and the manufacturer's installation manual. Power down or disarm the associated security panel before adding or replacing wireless sensor nodes. Mount the sensor at the manufacturer-specified height and angle to achieve the intended curtain detection pattern. Do not install in locations with direct sunlight exposure, heat vents, or other infrared sources that could cause false triggers.
