If using the primary ESFR connection
method above both jumpers must be
removed when the ESFR connection is
made to the drive.
•
If using the alternate method only the
jumper from Pin 9 to Pin 14 is removed.
1)
Primary Method - The Control is designed to take a PNP
(Sourced) +24 VDC signal from an ESFR fire suppression
system. The ESFR system will supply the +24V DC power.

o
The Drive will go in to an alarm condition when the
+
24VDC signal is lost. Fan operation is prevented
and the Control will stay in the alarm condition
until the +24VDC signal is restored.
2)
Alternate Solution - Run the output from Pin 9 (+24VDC) to a relay and run the output from the relay to Pin 14 (Digital Input 3 "DI3"). Control the relay with the ESFR fire suppression system.
