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.

.

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.

3.0 Wiring the FPP-RNAC-8A-4C

All terminals are fully protected against electrostatic discharge (ESD) and transients.

Use wire gauge based on Table 1 and Table 2. The terminals can accommodate up to 12 AWG (2.0 mm) wire.

Table 1: Wire Gauge Calculations

Line No. Description Calculation

1 Guaranteed minimum NAC voltage at full load.

3 Maximum wiring voltage drop
4 Total load for a given NAC
5 Maximum allowable line resistance
6 Total wiring run length (feet)
7 Total wire needed
8 Maximum wire resistance per foot
9 Choose a wire size with a resistance per foot less than Line 7.

14 (1.6 mm) 0.00258
16 (1.3 mm) 0.00409
18 (1.0 mm) 0.00651

NFPA 72 requires the use of 18 AWG
(1.0 mm) or larger diameter wire in fire
applications.

3.1 AC Power Connections

AC Power runs to the L (Hot VAC), G (Ground), and
N (Neutral) terminals.

120 VAC or 240 VAC with 8 A capacities should feed
the local power supply. The output voltage is a filtered

27.6 VDC (500 mV ripple maximum) under all
conditions.

A trouble condition is registered, but not indicated, if
AC power fails. A programmable time delay (refer to

Section

Subtract line 2 from line 1.

Divide line 3 by line 4.

Multiply line 6 by line 2.
Divide line 5 by line 7.

Disconnect all power (AC and battery)
before servicing the FPP-RNAC-8A-4C.
Wait 60 sec before handling any
connections.

4.6 AC Fail Time Delay on page 20) allows
the indication of AC Failure to be delayed by 0, 6, 12,
or 24 hrs. The default is 0 hrs.

Refer to

Figure 3 on page 9 for wiring details.

27.4 V

Remember to select the appropriate
voltage range for the AC input before
applying any power to the product.
