GAS | Q8 / B8 SERIES GAS | ## Call: 1-888-967-5224 | Web: www.workaci.com Q8 / B8 SERIES Combustible Gas Transmitter The Q8/B8 Series of Explosion Proof Gas Detectors are used in applications that require a rugged enclosure that meets the Class 1 Division 2 requirements. Each unit comes standard with an integral clock, digital display of concentration, relay status, STEL, TWA, and peak daily values of the gas being detected. A three color backlight will ash depending on the level of alarm for operator safety. Setup and calibration is accomplished through non-intrusive magnetic switches that allow for programming of all parameters. A remote sensor option is available for toxic and combustible gases and should be used in applications where the main unit can be mounted at 3 to 6 feet o of the oor with the remote sensor being at the ceiling or oor levels to monitor the gas concentrations depending on the gas being monitored. Sensor types include electrochemical and catalytic bead sensors to meet the demand and performance requirements for particular industries. The Q8 uses Optomux and Modbus RS-485 protocol, 4-20 mA, 1-5 or 2-10 VDC while the B8 uses BACnet™ MSTP(RS485) protocol to communicate directly with a BAS. The Q8/B8 also has three (3) SPDT Form 1C relays that are user adjustable. Calibration gases and 0.2 to 1 liter/minute ow limiting gas regulators are not available through ACI and should be purchased through your local gas supply company or companies such as Portagas® (Praxair®, Inc.) or Mesa Specialty Gases®. Refer to all applicable Federal, State, Provincial and Local Health and Safety laws and regulations before using these products. The Q8/B8-GENL can be ordered to monitor speci c combustible gases such as Gasoline, Ethanol, Diesel or Jet fuel. Contact ACI for speci c gases. Applications: Mechanical Rooms, Warehouses, Refrigeration Plants, Industrial Plants, Process Monitoring, Leak Detection, Parking Garages, Auto/Truck Maintenance Facilities, Oil and Gas Industry The Q8/B8 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, www.workaci.com.
