    Specification sheet for the SECO-LARM ENFORCER E-960/E-964 Series Twin Photobeam Detectors — outdoor perimeter beam detectors available in ranges from 90ft to 390ft, with built-in laser alignment for quick installation.

    Overview

    The Twin Photobeam Detectors provide reliable outdoor perimeter security by using twin beams, which minimize false alarms caused by falling leaves, birds, and other minor obstructions. Lensed optics reinforce beam strength and provide excellent immunity to false alarms from rain, snow, and mist. Built-in laser beam alignment makes installation quick and easy.

    Models & Range

    • E-960-D90Q — Outdoor range: up to 90ft (30m)
    • E-960-D190Q — Outdoor range: up to 190ft (60m)
    • E-960-D290Q — Outdoor range: up to 290ft (90m)
    • E-964-D390Q* — Outdoor range: up to 390ft (120m)

    *The E-964-D390Q also features four selectable beam frequencies.
