 "summary": "The TG is a Senva toxic gas detector with BACnet MS/TP. Each measurement (temperature, gas sensor 1 and 2, supply voltage) has a primary Analog Input plus Smoothed, Minimum, Maximum and Average objects. Analog Values hold the warning and alarm setpoints, hysteresis, sensor life and RS-485 settings; commandable Binary Outputs drive the fan relay, alarm relay and buzzer, and MSV 170 reports the Normal / Warning / Alarm / Extended Alarm state.",
