The ART is a state-of-the-art, fixed, non-dispersive infrared refrigerant
transmitter used to detect a wide range of refrigerant gases. It can be
used as a stand alone system or integrated into a building management
system (BMS).

WIRING
Either 24VAC or 24VDC may be used to power the ART. Use two wires
between 14 and 22 AWG stranded within conduit.

Available in two models - Broadband or Gas Specific - both with a fastresponding sensor that accurately detects refrigerant gas leaks without
cross interference with other gases.
The ART-B (broadband sensor) Transmitter is used as a cost-effective,
general purpose, gross leak detector and is factory tested and certified.
If distinct gas detection is required, the Gas Specific model is available
and is factory certified and calibrated to the target refrigerant.

KEY FEATURES
» Long life, non-dispersive infrared refrigerant sensor allows for accurate,
low level leak detection with no cross interferences from other gases
» Two models available: Broadband or Gas Specific
» Detects a wide range of refrigerants
» No field calibrations required
» Modbus RTU interface to connect to BAS/BMS systems
» On-board alarm relay
» Bright, alpha-numeric, LED display with visual and audible alarms
» User selectable, analog output: 4-20 mA, 0-5V, 1-5V, 0-10V, 2-10V
» RoHS compliant circuit boards

APPLICATIONS
» Supermarkets/Convenience Stores
» Refrigerated Mechanical Rooms
» Commercial Chiller Equipment Rooms
» Food Storage/Processing Facilities
» Wineries
» Schools
» Hospitals
» Maintenance Facilities
» and many more

For Modbus network
communications wiring, use only
18 to 24 AWG shielded twisted pair
wire with 120 ohm characteristic
impedance.

For analog output wiring, connect
two 18 to 20 AWG wires to
terminal block positions 5 and 6,
noting ground and signal poalrity.

For relay output wiring connect NO, NC or both, using 18 to 20 AWG wires
to terminal block positions 10, 11 and 12, noting normally open, closed
and common connectors.
