FPP-RNAC-8A-4C | Operation and Installation Guide | 1.0 Overview

1.0 Overview

The FPP-RNAC-8A-4C is a Remote Notification
Appliance Circuit (NAC) Power Supply designed to
add four additional NACs (NFPA 72 Class B, Style Y
or Class A, Style Z) to a Fire Alarm Control Panel
(FACP).

The FPP-RNAC-8A-4C is supervised by the control
panel. It consists of the controller board, backup
batteries, and enclosure.

The FPP-RNAC-8A-4C is also compatible with any
UL Listed control unit utilizing:

• reverse polarity supervised notification appliance
circuit (NAC) outputs, and

• 12 or 24 VDC regulated outputs.

Each output can be configured individually as a NAC
or constant 24 V auxiliary power supply.

1.1 Module Control

1.1.1 Option Bus Control

The FPP-RNAC-8A-4C can connect to the Option
Bus of the FPA-1000 or FPD-7024 Fire Alarm
Control/Communicator.

Refer to Section

14 for information on wiring.

page

1.1.2 Conventional NAC Input Control

For conventional panels, the FPP-RNAC-8A-4C
connects using the FACP’s NAC outputs that conform
to NFPA 72 Class A or B. Please refer to the control
panel’s NAC compatibility information.

1.2 Output Bell Operation

The FPP-RNAC-8A-4C can generate three pulsed
bell patterns on command in addition to steady
activation of the output:

• Pulsed: 60 PPM (0.5 sec On, 0.5 sec Off)

• NFPA Temporal: In compliance with ANSI

standard S3.41: 0.5 sec On, 0.5 sec Off, 0.5 sec
On, 0.5 sec Off, 0.5 sec On, 1.5 sec Off, and so
on.

• California March: 120 ppm (0.25 sec on,

0.25 sec off).

You can also implement SYNC protocols:

• Wheelock SYNC Protocol

• Gentex SYNC Protocol

• System Sensor SYNC Protocol

3.3 Option Bus Connections on

All outputs are synchronized if the
conventional inputs are activating the
FPP-RNAC-8A-4C.

For option bus synchronization
information, refer to the control panel
documentation.

1.3 Power Management

The controlling section of the board has un­interruptible power. If AC line voltage is lost, the
power supply switches to battery backup.

1.4 Low AC Line Detection

Sensing circuitry detects a line input voltage below
85 VAC, then switches from the primary AC Line
voltage to battery backup.

1.5 Ground Fault Monitoring

The option bus and polarity reversal inputs are
electrically isolated from the local power supply and
indicating circuits. The FPP-RNAC-8A-4C supervises
itself for grounded field connections and indicates a
fault condition if one is found. This feature can be
disabled by opening Switch S4.

For UL864 installations, do not disable
ground fault monitoring.

1.6 Circuit Supervision

Each NAC is supervised for short-circuit and open
conditions using an end-of-line (EOL) resistor on the
loop. Devices on these loops must have a blocking
diode on their input so that the EOL supervision
resistor can be read when the polarity of the output is
reversed in the standby state. The devices activate
when the polarity is switched back to normal in an
alarm state. The EOL is programmable from 1 kΩ to
20 kΩ. This allows existing systems to be retrofitted.

1.7 Overvoltage Supervision

The power supply output is monitored for overvoltage
conditions. If an overvoltage condition exists (30 V or
more on battery leads without the battery connected),
the trouble relay and EOL relays open. In addition,
the trouble LED lights. On the option bus, AC fail,
ground fault, and NAC troubles are initiated.

FPP-RNAC-8A-4C | Operation and Installation Guide |

.

1.8 Expander Supervision

A watchdog supervises the operation of the
FPP-RNAC-8A-4C processor and attempts to restart
it if it fails. If the processor does not restart, or the
power fails entirely, the installer-supplied EOL device

1.9 Auxiliary Power Supply

The FPP-RNAC-8A-4C can be wired to supply
unsupervised constant auxiliary power through its
NAC outputs. Refer to Section
on page

16 for additional information.

3.7.2 Auxiliary Circuits

disconnects from the input to report the trouble
condition. If power is available, the System Trouble
LED lights if the system encounters an error.

2.0 Installing the FPP-RNAC-8A-4C

The FPP-RNAC-8A-4C board and the enclosure are shipped together. The board, however, needs to be
mounted into the enclosure. Hardware for mounting the board in the enclosure is supplied in the hardware
pack.

outputs (refer to Section

Bus Settings

on page 17).

If the control panel detects a trouble condition on
either set of outputs, the appropriate EOL device is
disconnected from the reversal loop. These inputs are
electrically isolated from the controlling section of the
board.

3.5 Trouble Relay Connections

The trouble relay provides one set of Form C contacts
for connection of an appliance of choice. The relay
can be wired in series with the auxiliary output to
provide power to the appliance.

The relay deactivates by the controlling section of the
board to indicate a fault condition. Refer to
for wiring details.

Figure 9: Wiring the Trouble Relay

FPP-RNAC-8A-4C | Operation and Installation Guide |

3.6 Auxiliary Output Connections

The auxiliary output provides a continuous,
unsupervised 24 V output to power external devices.
It is rated at 0.75 A and can be wired in series with
the trouble relay to provide power to the associated
appliance.

A short circuit on this output causes a trouble
condition but does not affect the operation of the
FPP-RNAC-8A-4C in any way. Refer to
wiring details.

3.7 NAC Output Connections

Each of the four outputs provides up to 2.5 A at 24 V,
limited by an overall 8 A capacity.

3.7.1 NAC Circuits

Overload protection interrupts the circuit when given
an overload of 3 A or greater. When de-energized,
the circuit is supervised, which allows the reporting of
an open or shorted output condition. Refer to
Figure 11 on page 16 for wiring details. When the
total current draw from all four outputs and auxiliary
power exceeds 8 A, the output with the highest
current draw is turned off.

FPP-RNAC-8A-4C | Operation and Installation Guide |

3.7.2 Auxiliary Circuits

The FPP-RNAC-8A-4C can be configured to supply
constant auxiliary power through its NAC outputs.

Reverse polarity connections of some
notification appliances might not be
detected by the FPP-RNAC-8A-4C NAC
supervision. Ensure that the notification
appliances are connected properly and
tested before installation is completed.

Use DIP Switch S1 positions 3, 4, 5, and 6 (refer to
Figure 12) to make the output always active. When
the output is configured as always active, the output
is unsupervised and no EOL is needed.

3.7.3 EOL Reference Programming

Add a resistor that matches the value of the EOL
used in the notification appliance circuit. This must be
in the range of 1 kΩ to 20 kΩ. If no resistor is present,
the RNAC defaults to the value of 2.2 kΩ.

Positions 3 through 6 on Switch S1 control the output
mode.

• If the switch is OFF, the output is in NAC mode.

• If the switch is ON, the output is in power supply

(POWER) mode.

Each output can be configured individually to operate
in the NAC or power supply mode. When the output is
in the NAC mode, it follows either the option bus
command or the DIP switch settings depending on
the FPP-RNAC-8A-4C connection.

In the power supply mode, the output is turned on all
the time and is no longer supervised by an EOL. The
commands from the option bus and pattern settings
are ignored for any output configured in the power
supply mode.

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.

revision number. The green LED turns off to indicate the end of the sequence.
The display continues until the Flash module is removed from the programming
port. For example, revision number 2.04 has two blinks followed by a pause
and then four blinks.

Revision number display: When the TROUBLE RESET button is pressed
and held longer than 2 sec, the revision number shows. (Refer to
Reprogramming complete, above.)

AC input is OK; the power supply is operating from the AC line.
When LED 2 extinguishes, the AC fault relay activates after a programmed delay.
