Description
The advanced SL-200QDM offers enhanced features to minimize false and missed alarms due to misalignment and environmental factors. With a 200ft outdoor detection range and 4-channel beam frequency selection, the QDM model is ideal for high-security perimeter applications. Key features include:
– **Dual Modulation**: Improves signal discrimination to counteract potential interference.
– **Quad Beam Technology**: Significantly reduces false alarms triggered by birds and falling leaves.
– **Sniper ViewFinder and Alignment Sound Assist**: The enhanced telescope lens provides excellent visibility for optical alignment, ensuring precise installation and stable performance, even at 350ft.
– **Sunshine Protection Technology**: Features triple-layer construction for superior performance against external light sources such as the sun, vehicle headlights, mercury-vapor lamps, and fluorescent lighting.
– **Beam Power Control Selector**: Offers manual adjustment of beam power to prevent crosstalk from reflection, interference from unstable signals, or noise when deploying multiple beams over long distances, and enables usage at shorter-than-rated distances.
– **Automatic Transmit Power Control (A.T.P.C.)**: Automatically regulates beam power for optimal operation, decreasing false and missed alarms due to conditions like fog, frost, cross talk, and signal saturation.
– **BAU-4 Compatibility**: The BAU-4 beam alignment unit ensures precise optical alignment, enabling a single technician to accurately align the SL detector over distances of 200ft, 350ft, or 650ft.
