VLC-800MX VESDA LASERCOMPACT

3.24.1GENERAL

The VLC800 is a derivative of the standard VESDA LaserCOMPACT product family, with the primary difference that it communicates directly on the MX loop.

VESDA LaserCOMPACT detectors provide very early warning of potential fire conditions by drawing air samples through 25mm pipe up to 80m long. Smoke is sampled through holes in the pipe and transported to the detector by an integrated aspirator or fan. Holes are positioned according to the application and often follow the spacing of standard conventional point detectors. Where necessary, sampling points can be constructed using capillary extensions.

The VLC800 alarm sensitivity can be set to between 0.005% obscuration / m and 20% obscuration / m. A PC plugged into the VLC800 is required to set the sensitivity, to normalise the airflow, and perform other setup functions. The sensitivity is NOT controlled at the MX4428.

Refer to Tyco Safety Products UK publication 17A-03-VLC for further details on installing, commissioning and servicing the VLC-800.
