 "summary": "The GWNP is a wall platform that carries one replaceable Veris AG gas sensor (single or dual gas) and reports it over BACnet MS/TP or Modbus. It exposes the gas readings, sensor life and runtime, writable high/low alarm setpoints and hysteresis, two setpoint-exceeded BIs and BVs to override the two relays.",
