**Modification to the K3 common alarm relay on the microprocessor controls of the Environmental unit is necessary to enable remote on/off – this modification will necessarily eliminate the common alarm relay output. Refer to the Installation / Operations Manual of the Environmental unit, or consult Liebert Environmental Support.

Note that if the high/low temperature and humidity alarm setpoints are disabled at the unit controls, then the MR1 will display 00 for the setpoint. The MR1 is not able to remotely enable alarm setpoints.

The MR1 will annunciate any alarm transmitted by the Environmental controls. Table 4 catalogs the available alarms by microprocessor level.
