 "summary": "The 8631-HM monitors isolation room pressure (negative, positive or no isolation) with an optional second sensor and a flow input, and alarms on pressure and minimum flow. With the BACnet board it is a BACnet MS/TP device exposing pressures, flow, air changes per hour, alarm limits, a Status Index alarm code and the room control mode.",
