4.4 Option Bus Address
To activate a new address, remove the
AC and battery power from the
FPP-RNAC-8A-4C. Wait 60 sec. Restore
the power after it is removed. The new
address becomes active after power is
restored to the FPP-RNAC-8A-4C.
The FPP-RNAC-8A-4C needs its own address
(1 to 14) when using the option bus connection. Use
Switch S2, Positions 3 through 6.
Refer to
Figure 13 on page 22 for the correct DIP
switch positions.
4.5 NAC Input Variable
Instead of having Input 1 drive NAC Output 1 and 2
and Input 2 drive NAC Output 3 and 4, Input 1 can be
set to drive all four outputs. Set Switch S1 to the ON
position to select this option.
4.6 AC Fail Time Delay
A trouble condition is registered to the control panel
but is not indicated with an LED if the AC falls below
85/105V for more than 5 sec. A programmable time
delay allows the indication of AC failure to be delayed
by 0, 1, 3, or 6 hr. The default value is 0 hr.
Use Switch S2 positions 1 and 2 for these settings.
UL864 requires that off-premises
signaling of AC Trouble is delayed
between 60 and 180 minutes.
To comply with this requirement:
• Set the AC Fail Time Delay to 0, and
• Program the FACP to delay the off-
premises AC Trouble signal to a
value between 60 min and 180 min.
