Appendix C
Using The FACP Input and FACP AUX Output Terminals
The APD8(F) has two FACP inputs which can be used to drop power to selected outputs when activated. One of the
FACP inputs is for connection to a voltage source trip, while the other is for connection to a NO contact trip or open
collector trip. See Section 3.6 for more information. The FACP voltage input incorporates an on-board blocking diode for
connection to a polarity-reversing source.
The FACP AUX relay output follows the FACP input and can be used to activate additional APD8(F) FACP inputs, to latch
the FACP input on, or for other functions. See Section 3.7 and Appendix D for more information.
Applying voltage in the polarity shown
will activate the FACP input.
Activation of the open collector output
will activate the FACP input.
Closure of the NO contact will activate
the FACP input.

Activation of the FACP’s output causes the APD8(F)’s FACP voltage input to be activated. This causes the APD8(F)’s FACP
AUX relay to activate, which provides a closure across the APD8(F)’s FACP dry contact input, holding the APD8(F) in FACP
mode. Opening the reset contact will unlatch the FACP mode as long as the FACP’s output is deactivated.
