## Replacement Smart Sensor **Assembly for Q5/B5, Q6/B6 Sensors** 

## **Description** 

The smart sensor assembly is a factory calibrated replacement module for the Q5/B5 or Q6/B6 series of toxic, combustible or IR gas detection to make maintenance quick and easy. The boards are easily replaced in the field by removing two screws on the previous module and the replacement board installed. All units should be checked for proper functionality and calibration once the replacement sensor module is reinstalled and has had a chance to warm up. 

See Q5/B5 or Q6/B6 data sheets for technical specs. 

## **Warranty** 

The Q5/B5 Series Gas Transmitters are covered by ACI’s Two (2) Year Limited Warranty against defects in material and workmanship from the date of shipment with the exception of the Sensor Modules (Electrochemical/Toxic: Six Months and Catalytic/Combustible: One Year). The warranty can be found in the front of ACI’s Sensors & Transmitters catalog, as well as on ACI’s website, workaci.com.
