The PolyGard®1 Series is sunsetting and superseded by our next-generation PolyGard®2 — product availability is significantly limited.
Wall mounted, microprocessor-based, multi-point, RS-485 digital communicating system for various gas, temperature and humidity detection, control and alarm.
Optional data logging function provides internal recording of time/date stamped sensor values, alarms, and system errors. This data is highly valuable during system commissioning and with periodic analysis, ensures long-term system performance.
To control and alarm upon the presence of any toxic, combustible and refrigerant gases. A combination of the RS-485 communicating DT5 series and analog AT series, or other 4-20 mA transmitters piggy-backed via a digital DT5 transmitter, can be connected to the control unit. The controller interfaces via binary outputs, 4-20 mA signals, and/or optional BACnet or Modbus port with any compatible electronic control, DDC/PLC control or automation system.
