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
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 4-36.

2. Program the NAC circuit for non silence NAC circuit (see Section 7.4.1).
Note: If you need to transmit supervisories or trouble conditions, additional relay modules must be added. Use
relay 1 to transmit supervisory conditions. Use the trouble relay to transmit trouble conditions.
