4.12.4 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.
To install the MR-201/T for polarity reversal, follow the steps below.
1. Wire the MR-201/T as shown in Figure 4.31.

2.
Program the NAC circuit for non-silence NAC circuit (see Section 7.5.2).
4.12.5 Transmitter Activated by Dry Contacts
This section describes the connection of a UL Standard 864 listed remote station transmitter to the GWF-7075 FACP dry contacts. The
FACP contacts must be supervised by the remote station transmitter module using end-of-line resistors (ELRs) with a value determined
by the transmitter manufacturer. Power is also provided by the remote station transmitter manufacturer. Refer to the remote station trans-
mitter manufacturer’s manual for details.

NOTE: If you need to transmit supervisory or trouble conditions, you must add more relay modules. Use relay 1 to transmit
supervisory conditions. Use the trouble relay to transmit trouble conditions.

With power applied to the FACP and no
troubles in the panel, the contacts should
be in the condition indicated in the drawing.
CAUTION:
Do not use looped wire below terminals
for the following:
- System Supervision
- Terminals labeled Relay 1, Relay 2
- Trouble
Break wire run to provide supervision of
connections.
