• Multi-frequency: Four selectable beam frequencies to eliminate interference between multiple units for flexible perimeter protection.
• Automatic input power filtering with special noise rejection circuitry.
• Environmental Output: Signal is sent if a degradation in environmental conditions is detected such as thickening fog to prevent false alarms.
• Audible beam alignment (buzzer), beam strength indicator, and laser alignment make transmitter and receiver alignment faster.
• Voltage testing points for fine tuning the beam alignment. Input voltage: 12-24 VDC/VAC (non polarized).
• Delay time adjustable for nearly all applications.
