Seco-Larm - E-9655-8S328DA - Curtain Barrier Sensor – 8 Beams
Product Overview
ENFORCER Long-Range Curtain/Barrier Sensors are designed for indoor and outdoor perimeter security in areas such as windows, doorways, skylights, fence tops, walls, and other confined spaces. They use multiple photobeam sensors with programmable trigger options, long-range detection, and weatherproof construction for reliable barrier protection.
Key Configuration
Long-range curtain/barrier sensor available with 4, 6, or 8 photobeam sensors; 9~30 VDC operating voltage; supports synchronous range up to 328 ft. / 100 m and asynchronous range from 33 to 262 ft. / 10 to 80 m.
Key Features
• Programmable trigger activates by breaking two adjacent beams or any single beam
• Two selectable frequencies help avoid interference from nearby sensors
• Optional synchronization wire helps prevent crosstalk in close-proximity applications
• Four adjustable sensitivity levels support range-specific tuning
• IP65 weatherproof aluminum alloy construction supports outdoor use
Technical Context
The sensor supports both synchronous and asynchronous operating modes, allowing installers to select the best configuration for range and interference control. It includes NO/NC relay output and an N.C. tamper alarm output for integration with security and access monitoring systems.
Installation Notes
A buzzer alignment indicator with up to 180° horizontal rotation helps simplify beam alignment during installation. The rugged housing uses aluminum alloy construction with a polycarbonate lens tube and end caps, and mounting hardware is included.
