Seco-Larm - E-964-S65TB - Mini Photobeam Sensor
Product Overview
ENFORCER Mini Photobeam Sensors are compact perimeter security sensors designed for indoor and outdoor alarm applications. They provide sensing range up to 65 ft. / 20 m, selectable frequencies to reduce interference, and IR signal processing to help maintain reliable operation in challenging environmental conditions.
Key Configuration
Mini photobeam sensor with sensing range up to 65 ft. / 20 m; flexible power input of 12~24 VDC or 12~20 VAC; switchable NO/NC output for compatibility with various alarm control systems.
Key Features
• Four selectable frequencies help reduce interference in multi-pair installations
• Built-in IR signal secondary processing filters lighting disturbances
• Small size supports less conspicuous installation
• Signal strength indicator helps simplify alignment
• IP55 weatherproof rating supports indoor and outdoor use
Technical Context
The wide-voltage input range helps reduce issues related to voltage drop on longer wiring runs. LED indicators for power, signal strength, and alarm trigger provide clear status feedback during setup and operation.
Installation Notes
The sensors are designed for simple installation and include mounting hardware. Selectable frequencies allow multiple sensor pairs to be installed nearby while minimizing interference between units.
