FACP ZONE OR MONITOR MODULE
The WRX-R contains a normally
energized, failsafe relay. Under normal
conditions, it internally connects the NO
terminal and the EOLR resistor symbol
terminal. A loss of power or any trouble
condition causes the relay to drop out
and open the EOLR circuit, this creates
a trouble on the fire panel.
24 VDC at 55mA
From AUX power of FACP or other listed
