Paradox 2661000908-P2C Curtain Fresnel Lens 1 (CU-1)

The Paradox 2661000908-P2C (CU-1 / Curtain 1 Lens) is an official replacement optical curtain Fresnel lens designed specifically for Paradox indoor motion detectors (including DG55, DG65, 525D, DM50, DM60, and PMD2P). Replacing the standard wide-angle lens with the CU-1 transforms the motion detector into a barrier curtain sensor, creating a precise vertical detection wall spanning 10.5 meters (35 feet) across windows, glass doors, and entryway perimeters.

Key System Features & Functionality

• Curtain Barrier Pattern: Converts wide PIR coverage into a tight 10.5m x 1.5m (35ft x 5ft) vertical coverage plane, protecting doors and windows while allowing free movement inside the room.

• Perimeter Intrusion Detection: Ideal for wall-skirting applications and guarding glass storefronts or sliding balcony doors against unauthorized entry.

• Universal Paradox Compatibility: Precision-molded to fit directly into Paradox DG55, DG65, 525D, DM50, DM60, and PMD2P motion detector enclosures.

• UV-Stabilized Polyethylene: Durable optical polymer engineered to maintain full infrared transparency without yellowing or cracking over time.
