Lens for SATEL motion detectors LR — replacement optical lens for detector modules

Replacement optical lens compatible with SATEL motion detectors, model LR. This lens is designed to shape and focus infrared detection zones in detector modules, allowing precise restoration or modification of coverage patterns for PIR and combined motion detectors. Intended for maintenance, repair, or customization of alarm and security sensor installations, it fits into the detector's optical assembly to influence detection range and zone segmentation.

Advantages

The LR lens provides consistent optical performance to maintain the original detection geometry of SATEL motion detectors. It offers repeatable focusing characteristics to ensure reliable sensor responses after replacement or adjustment. The lens is made to integrate with detector modules without requiring major mechanical changes, simplifying maintenance and reducing downtime during installation or servicing.

Suitable for

• Repairing or replacing damaged detector optics in SATEL motion detectors
• Restoring original detection patterns after sensor servicing
• Customizing or adjusting coverage zones for specific installation layouts
• Maintenance tasks in alarm and security sensor systems

Key specifications

• Optical type: molded lens for infrared motion detection
• Compatibility: designed for SATEL motion detector modules (LR model)
• Function: shapes and focuses PIR detection zones
• Material: optical-grade polymer suitable for sensor housings
• Mounting: snap-fit or press-fit into detector optical assembly

How to use

Power down the detector and follow the manufacturer's service instructions to access the optical assembly. Remove the damaged or existing lens carefully, avoiding contact with the detector's sensor surface. Install the replacement LR lens by aligning it with the detector's lens seat and applying gentle pressure until it secures in place. After reassembly, restore power and verify detection coverage and sensitivity in the intended zone, adjusting detector position or settings if required.

Usage recommendations

Handle the lens by its edges and avoid fingerprints on optical surfaces. Test the detector after installation to confirm correct coverage and perform any fine adjustments to detector orientation or sensitivity settings according to the installation environment.
