The PolyGard®1 Series is sunsetting and superseded by our next-generation PolyGard®2 — product availability is significantly limited.
Digital RS-485 communicating, addressable gas transmitters, for the detection of carbon monoxide (CO) in the ambient air for direct daisy-chain/multi-drop link to the DGC digital controller. Standard units communicate with DGC Series controllers only. Optional Modbus or BACnet-MSTP communications for connection to other controllers.
Included 4-20 mA analog input channel can also be used for remotely monitoring any additional gas detection or environmental sensor.
To sense carbon monoxide (CO) in a wide variety of commercial and industrial applications, such as vehicle exhaust in parking structures, engine repair shops, tunnels, equipment rooms and ventilation systems, etc., and to transmit to the DGC central controller unit or other Modbus/BACnet master device.
