Optional Module Installation
Programming
Following installation and wiring of the N-ANN-100 LCD annunciator to the FACP, the annunciator must be added to the system via
FACP programming. Refer to the programming section titled "ANN-BUS Setup" on page 86 in this manual for detailed programming
information.
Trouble Response
If the N-ANN-100 is installed but the ANN-BUS is not enabled at the FACP, the N-ANN-100 will indicate a trouble condition by NOT
turning on its AC Power indicator. The LCD will also display Key Bus Trouble and the piezo will sound approximately once every 10
seconds. Note that the FACP will provide no indication of an N-ANN-100 trouble.
To clear the N-ANN-100 trouble condition, enable the ANN-BUS and program the address corresponding to the address set on the N-
ANN-100 at the FACP.
N-ANN-S/PG Serial/Parallel Interface Module
Installation
1.
Ensure that all power (AC and DC) has been removed from the FACP.
2.
Connect the N-ANN-S/PG to the FACP as illustrated in Figure 2.21
3.
Using the DIP switches on the back of the N-ANN-S/PG module, assign an ID number (address) to the module.
4.
Select the address and configuration options for the N-ANN-S/PG module as described in the Programming section of this manual
(refer to "ANN-BUS Setup" on page 86).
Note that the Auto-configure feature allows the programmer to quickly bring all installed ANN-BUS modules online (refer to
"Auto-Configure" on page 93).
5.
Connect a printer to the N-ANN-S/PG Parallel or Serial connectors (refer to Figure 2.21). Only one printer can be connected.

Connecting a PRN-7 Printer
Remote printers require a primary AC power source. If required for the fire alarm system configuration (for example, a Proprietary Fire
Alarm System), a remote printer requires a secondary power source (battery backup). Since a secondary power source is not provided as
a standard feature, a separate UL-listed Uninterruptible Power Supply (UPS) should be used. The building emergency power supply may
be used, as long as it meets the power continuity requirements of NFPA 72. Refer to NFPA 72 for further details.
Connect the remote printer to the FACP via the N-ANN-S/PG module using a standard DB-9 cable. One end of the cable will plug into
the DB-9 connector on the PRN-7 printer and the other end plugs into the serial connector on the N-ANN-S/PG module.
