Optex FTN-RAM Outdoor Wireless Pir Detector Anti-masking

Product Description

The OPTEX FTN-RAM is a compact outdoor passive infrared (PIR) detector designed for wireless security installations where anti-masking capability is required. It monitors an exterior zone for motion and transmits alerts without hardwired signal runs, reducing installation time on retrofit and new-construction projects alike. The anti-masking function detects attempts to obstruct or defeat the sensor lens, providing an additional layer of tamper resistance. Security integrators and alarm technicians install this unit on building exteriors where perimeter detection is needed and wiring runs are impractical or cost-prohibitive.

This detector is suited for residential and light-commercial perimeter security applications. It is mounted on exterior walls or structural surfaces covering entry points such as doorways, gates, and covered walkways. The wireless design makes it a practical choice for installations where conduit or cable runs would be disruptive or structurally difficult. Its compact housing allows for discreet placement in areas where a low-profile sensor profile is preferred.

Key Features

• Passive infrared detection for reliable outdoor motion sensing
• Wireless transmission eliminates hardwired signal cabling
• Anti-masking technology detects lens obstruction or defeat attempts
• Compact form factor supports discreet exterior mounting
• Designed for perimeter security on residential and light-commercial properties

Compatibility

Designed as an OEM-style replacement or addition for wireless outdoor PIR security systems requiring anti-masking capability. Refer to system documentation to confirm receiver and panel compatibility before installation.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm systems technician familiar with applicable local codes and NFPA 731 guidelines for premises security equipment. Power down or disarm the associated wireless receiver and control panel before mounting or pairing the device. Mount the unit to a stable exterior surface using appropriate fasteners for the substrate, keeping the detection zone free of obstructions such as vegetation or HVAC equipment that could cause false triggers. Do not paint over or apply film to the sensor lens, as this may impair detection performance and trigger anti-masking alerts.
