Product Description
1.6.7 ANN-BUS Annunciators/Modules
WARNING: RISK OF ELECTRICAL SHOCK AND EQUIPMENT DAMAGE
!
DISCONNECT ALL SOURCES OF POWER (AC AND DC) BEFORE INSTALLING OR REMOVING ANY MODULES OR
WIRING.
Guidelines
•
A variety of optional annunciation devices can be connected to an ANN-BUS communication circuit. ANN Series devices can be
connected to the primary communication circuit (EIA-485) terminals on TB9. A secondary communication circuit for these devices
is available at TB8. Each ANN-BUS communication circuit supports up to eight (8) annunciators. Compatible devices include the
following:
– N-ANN-80 LCD Annunciator (UL applications only)
– N-ANN-100 LCD Annunciator (FM applications only)
– N-ANN-S/PG Serial/Parallel Printer Interface Module
– N-ANN-I/O LED Driver Module
– N-ANN-LED Annunciator Module (alarm, trouble, supervisory LEDs)
– N-ANN-RLED Annunciator Module (red alarm LEDs only)
– N-ANN-RLY Relay Module (can be mounted in the supplied FACP chassis)
•
When operating two ANN-BUS circuits, only one N-ANN-S/PG Printer module can be used in the system.
•
The panel is capable of operating a primary ANN-BUS (TB9) and a secondary ANN-BUS (TB10) simultaneously.

ANN-80 and
The N-ANN-80 and N-ANN-100 Annunciators are 80 character, backlit, LCD remote fire annunciators. They mimic the display on the
control panel and will annunciate device type, point alarm, trouble or supervisory condition, zone assignment plus any custom alpha
labels programmed into the FACP. The annunciators also provide system status LEDs to display AC Power, Alarm, Trouble, Supervisory
and Alarm Silenced conditions. Additionally, the annunciators are capable of remotely performing critical system functions such as
Acknowledge, Silence, Reset and Drill. Communication between the N-ANN-80/N-ANN-100 and the FACP is accomplished over a two
wire RS-485 serial interface employing the ANN-BUS communication format. The devices are powered, via two additional wires, from
either the host FACP or remote UL-listed, filtered, regulated power supply.
The function buttons, keyswitch and piezo sounder may be individually enabled and disabled through the FACP software. Refer to
"ANN-80/100 Options" on page 94 for a description of this feature and programming information.
Note that if the keyswitch is enabled and remains in the unlocked position for more than two minutes without any buttons being pressed
on the annunciator, a trouble indication will be annunciated.
N-
ANN-S/PG Serial/Parallel Interface Module
The N-ANN-S/PG Serial/Parallel Interface module allows the connection of a remote serial or parallel printer to the FACP for a real-
time log of system events, detector status reports and event history. The module is provided with a plastic enclosure for surface mount-
ing.
N-
ANN-I/O LED Driver Module
The N-ANN-I/O is an LED driver module that can be used in a wide variety of applications, including as an interface with most custom-
ized graphic annunciators. The N-ANN-I/O can drive up to 40 LEDs. The module is provided with a plastic wall mount.
N-ANN-LED Annunciator Module
The N-ANN-LED and N-ANN-RLED annunciator modules provide LED annunciation of general system faults and input zones/points
when used with a compatible FACP. The N-ANN-LED module provides alarm (red), trouble (yellow) and supervisory (yellow) indica-
tion for up to ten input zones or addressable points. The N-ANN-RLED provides alarm (red) indication for up to 30 input zones or
addressable points. Multiple N-ANN-(R)LED modules may be used for full system coverage.
N-
ANN-RLY Annunciator Module
The N-ANN-RLY relay module provides 10 programmable Form-C relays when used with a compatible FACP.
