Confirm the detector voltage, alarm-unit voltage, detection range, mounting method and linkage version before ordering. Professional installation and grounding are required, and the laser detection path must remain clear.
Check the capabilities that matter before you choose a configuration.
The features that most directly affect how this model works and where it fits.
The laser detector continuously monitors the configured clearance zone. When a vehicle, person or obstacle enters the restricted height range, the system automatically activates the alarm output until the target leaves.
The linked alarm unit provides adjustable sound output from 0–120dB together with visual warning. Alarm voice files can also be updated through an external USB cable.
The system supports passive dry-contact output for connected alarms, warning lights, displays, gates or other equipment. RS485 is available for distance adjustment, with optional 433MHz wireless alarm linkage.
Quick technical checks before ordering.
The YASONG SLA-PT8020 is a laser-triggered overheight alarm siren system designed to automatically detect vehicles or obstacles that enter a restricted clearance zone and activate a high-output sound and light warning. It is suitable for tunnels, bridges, factory entrances, loading areas and other height-restricted access points.
The laser detector continuously monitors the preset clearance zone. When a target enters the configured detection range, the alarm output remains active until the obstruction leaves. Choose between 0.5–10m or 0.5–20m detection versions, with automatic calibration, passive dry-contact output and optional 433MHz alarm linkage.
Confirm the detector voltage, alarm-unit voltage, detection range, mounting method and linkage version before ordering. Professional installation, wiring and grounding are required, and the laser path must remain clear of obstructions.
