Connections
1.
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 termi-
nal block. Leaving some slack inside the unit.
Replace the housing to the base plate.
Fit the tamperproof screw (if required) through the
lug at the bottom of the base plate.
Power the unit with 24Vac/dc and after a stabilising
period of 2-3 minutes functionality checks can be
made.
Pre-commissioning checks are made after approxi-
mately 30 minutes. Final commissioning should only
be carried out after the unit has been running for a
minimum of seven days.

Operation
The
GS-AQ911
space air quality transmitter is most suited
to areas such as common rooms, canteens, office spaces
and other areas where pollutants given off by occupants are
of concern.
The typical pollutants of which the
GS-AQ911
would monitor
are body odours, methane, solvent gases, cigarette smoke,
carbon monoxide, alcohol, perfume and most other heavy
odours related to high occupancy.
The normal operation of the
GS-AQ911
is to set the damp-
ers to minimum fresh air at below 2Vdc. As the signal in-
creases, dampers should be modulated to fully open at 8-
10Vdc.
Trend Scaling
Typically, the output could be scaled for 0 to 100% contami-
nation.
