R1
(See NOTE 1) End of line
resistor for FACP Signal Circuit.
NOTE 1: If the Fire Alarm Signal Circuit requires a
4.7K end-of-line resistor, then R1 must be a 4.7K.
Normally, this resistor is connected to the Signal
Circuit through a closed Trouble contact. When the
EVAX 25/50/100 goes into Trouble, the contact
opens, producing an "Open" on that Signal Circuit,
notifying the FACP.

END OF LINE RESISTORS
SET EOLR
R2
(See NOTE 2) Sets the
value of the end of line
resistor for the Speaker
Circuit.
R3
(See NOTE 2)
End of line resistor for Speaker Circuit.
NOTE 2: R2 and R3 must match each other. R2
"Sets" what the value of R3 needs to be. R2 tells the
EVAX 25/50/100 what to expect on the end of the
Speaker Circuit. If a Speaker EOLR (R3) already
exists, simply match that value for R2.
