    Refer to the Installation Instructions if there is any question as to whether the monitor has been installed properly. Safety Information This section gives instructions to promote safe and proper handling of Model RPM10 and RPM20 Room Monitors. There are no user-serviceable parts inside the instrument. Opening the instrument case will void the warranty.

    ALARM RESET). Alarm Relays The PresSura monitors feature 2 alarm relays. The alarm relays can be field configured to either open or close to indicate an alarm condition, although they will close on loss of power. Relay 1 functions as the low alarm relay, and will activate after the alarm delay for low pressure, low flow, low temperature and low RH alarms.
