GENERAL INFORMATION

VOCs are emitted as gases from certain solids or 
liquids, such as building materials and furnishings, 
office equipment, cleaners and disinfectants, etc. 
These types of contaminants directly affect indoor air 
quality and occupant comfort. Measuring and 
communicating VOC levels back to the BAS will help 
users adjust ventilation to maintain proper IAQ 
levels. These units utilize a high-performance metal 
oxide sensor and will output TVOC levels in a range 
from 0-1000 ppb. All units come equipped with both 
analog and RS485 Modbus RTU outputs easily 
interface into existing BAS systems. 

IMPORTANT PRECAUTIONS

Read the following instructions carefully before 

using the indoor air quality sensor described in 

this document to avoid erroneous readings and 

to prevent the device from permanent damage.

•  The sensor must not be exposed to high 

concentrations of organic solvents, 

ammonia, silicone vapour or cigarette-smoke 

in order to avoid poisoning the sensitive 

layer.

MOUNTING INSTRUCTIONS

For optimal temperature readings, follow these 

tips:  

Do not install on external walls. 

Avoid air registers, diffusers, vents, and windows 

Avoid confined areas such as shelves, closed cabinets, 

closets, and behind curtains.

Eliminate and seal all wall and conduit penetrations. 

Air migration from wall cavities may alter 
temperature readings. 

Do not install near heat sources. eg: lamps, radiators, 

direct sunlight, copiers, chimney walls, walls 
concealing hot-water pipes

OPENING COVER

Separate the cover from the base by inserting a 
flat head screwdriver into the top slot marked 
“OPEN”. Pry the cover forward. 

Attach the base directly to the wall or to a 
standard 2” x 4” junction box using (2) #6-32 x 1” 
screws.
