QIRF-0R11X-0 | ACI: FREON, R11, N4, LCD, 3 X SPDT
OVERVIEW | ACI: FREON, R11, N4, LCD, 3 X SPDT
QIRF Refrigerant Gas Detectors from ACI are the second generation of a proprietary designed gas detector that is easily configured to meet International Mechanical Code, ASHRAE 15 and B52 requirements. These transmitters are engineered to address the deficiencies inherent with solid-state sensors. Infrared technology facilitates specific gas type refrigerant detection without any cross-sensitive interferences.
Standard features include a digital display, three user configurable relays, buzzer, horn/strobe output, NEMA 4X enclosure and non-intrusive calibration. Sensor Housings are thermally controlled at elevated temperatures to eliminate errors due to condensation forming and from temperature fluctuations allowing operations in temperatures from -49 to 149ºF (-45 to 65ºC). Analog outputs of 4-20 mA and or 2-10 VDC are available along with RS-485 Communications that can be used with a Modbus RTU or proprietary OptoMux communication protocol for use with any of the standalone gas controller such as the Q4C, M-Controller or Q-Controller. A Zero gas of 20.9% Oxygen with the balance Nitrogen should be used to perform a Zero calibration while a known concentration of any span gas can be used to perform yearly bump testing and calibration. Never use 100% Nitrogen gas to perform a Zero calibration on the QIRF transmitters. Calibration gases and a 0.4 to 0.6 liter/minute flow limiting gas regulator are not available through ACI and should be purchased through your local gas supply company or on-line companies such as Portagas® (Praxair®, Inc.) or Mesa Specialty Gases®. ACI also offers a full line of horns and strobes that can be used with the Gas detectors or building management system to alert building occupants of an alarm condition in order to meet B-52 or other code requirements. Refer to all applicable Federal, State, Provincial and Local Health and Safety laws and regulations before using these products.
For convenience in installing a complete building automation system, KMC Controls sells to our customers a large variety of ACI (Automation Components, Inc.) devices.
