GS-AQ911 Datasheet | Sontay

Overview The GS-AQ911 is wall-mounting air quality transmitter designed for use for the control of fresh air for ventilation purposes. The GS-AQ911 measures the level of contaminant gases in an air sample, and is sensitive to most heavy odours, smoke, solvent gases etc., providing an output proportional to the mixed gas concentration. This signal can be used to control fresh air fans and dampers according to the ventilation load. Where the primary contaminant load is human respiration, it is remended that a Carbon Dioxide transmitter is used.

Undo the tamperproof screw at the bottom of the housing and gently pull the front panel from the base. Using the base as a template mark the hole centres and fix to the wall with suitable screws. Alternatively the base plate can be mounted on to a conduit box or a standard recessed back box. Feed cable through the 22mm knockout in the base of the housing and terminate the cores at the terminal block. Leaving some slack inside...
