To acknowledge the alarm, press the button below ACK. You will be returned to the ALARM SUMMARY
SCREEN and the box associated with that alarm will no longer be blinking, indicating that the alarm has
been acknowledged. Repeat this procedure for each active alarm. When all alarms are acknowledged the
red alarm light will go out on the HGM300 and the alarm relays will de-activate. All pending alarms across
the entire network must be acknowledged before the RDM800 returns to normal operation. Once this
occurs, the RDM800 red alarm light will go out and its relays will de-activate.
NOTE: If there is still sufficient refrigerant gas present, the system will go back into alarm!
