FlexIO Connectors
These connectors pass the FAI and Fault signals to and
from the C4/C4P/C8/C8P board and pass the FlexIO buss on
to other accessory boards in the system.
2
Fault LED (FLT) – Yellow
This LED lights when the C4/C4P/C8/C8P detects a ruptured
output fuse. This fault condition also transmits to the FPO
power supply.
3
Zone Inputs (IN1 – IN4/IN8)
These are the zone input terminal strips. These terminal strips
are removable and accept wire sizes from AWG14 – AWG22.
The terminals are labeled on the PC board near the terminal
strip. See the Input Wiring section of this manual for more
information.
• When using a relay contact input, the contact is connected
across the A and B terminals. When configured for a relay
contact input, it is normal to measure a voltage across these
two terminals. This voltage is current limited and will not
damage the activation contact.
• When using a voltage input, the voltage is connected to
the B terminal. The activation voltage must be common
grounded with the system voltage. The activation voltage
must be between 12 and 24VDC nominal.
• When using an open collector (transistor) input, place a jumper
across the A and B terminals and connect the open collector
to the B terminal. Note that the input source must be common
grounded with the C4/C4P or C8/C8P board’s power source.
4
Configuration Jumpers (xA–xF)
These jumpers program the zone’s input, output, and FAI
operation. Jumpers are color coded for ease of program-
ming and jumper numbers correspond with the zone
number (e.g. 1A is jumper A for Zone 1).
OBSERVE JUMPER ORIENTATION CAREFULLY - See the
Common Jumper Settings Chart for more information.
Jumpers and their possible settings are as follows:
• Jumper A - RED (Zone FAI Enable)
This jumper enables or disables FAI for the selected zone.
The FAI control input is on the FPO power supply board.
See Appendix A of the FPO manual for more information
on the FAI Input.
Pos. 1 (FAI Enabled) When this jumper is placed in posi-
tion 1, the zone's output will invert when the input
is active. This is typically used to drop power to
maglocks on a fire alarm condition.
Pos. 2 (FAI Disabled) When this jumper is in position 2,
FAI will have no effect on the zone's output.

Note: The relay contact output
has a suppression diode across
it, and cannot be used to switch
AC voltage.
To switch DC voltage with these
contacts, Terminal “B” should
be positive, “A” negative.”
