    VESDA VLQ Product Guide VESDA by Xtralis Features The VESDA VLQ detector provides the following features: Laser-based absolute smoke detection Clean air barriers for optics protection Up to 100 m² (1000 ft²)coverage Up to 2 x 6m (2 x 20ft) pipes (straight), up to 2 x 9m (2 x 30ft) pipes (branched)

  • Page 11: Product Information

    Product Information How it Works The VESDA VLQ detector continually samples air from the protected environment via two pipe inlets for the sampling pipes on each side of the pipe inlets (A1, A2). Upon entering the detector, the air passes through respective inlet manifolds (B1, B2) and the aspirators (C1, C2).
