Seco-Larm - E-9643-6S328DA - Curtain Barrier Sensor – 6 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 behavior, long-range detection, and rugged weatherproof construction.
Key Configuration
Long-range curtain/barrier sensor available with 4, 6, or 8 separate 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 simultaneous breaking of 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 tuning for different ranges
• IP65 weatherproof aluminum alloy housing supports outdoor installation
Technical Context
The sensor supports synchronous and asynchronous operating modes, allowing installers to select the best configuration for distance and interference control. It includes NO/NC relay output and an N.C. tamper alarm output for integration with security monitoring systems.
Installation Notes
A buzzer alignment indicator with up to 180° horizontal rotation helps with setup and beam alignment. The sensor includes a rugged aluminum alloy housing, polycarbonate lens tube and end caps, and mounting hardware for installation.
