Using a MR-201/T Control Relay From Air Products
When the MR-201/T control relay is wired for polarity reversal, it reports alarm and trouble events to a remote site. Alarms will override
trouble conditions and it will not be possible to reset the remote indicator until the condition is cleared and the control panel is reset. If an
alarm condition occurs, the alarm relay will close, overriding the trouble condition.
