4.13.5 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.
Current: 15 mA max.
Operating Voltage: 24 VDC nominal; 27.4 VDC max.
Resistance: 4 K

To install the MR-201/T for polarity reversal, follow the steps below:
1. Wire the MR-201/T as shown in Figure 4-38.
