NOTIFIER N-ANN-I/O LED Driver Module

N-ANN-I/O LED Driver Module

Miscellaneous
General

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 the Fire Alarm Control Panel (FACP) to drive most customized graphic annunciators. It comes in a plastic enclosure that may be mounted inside a custom annunciator or accessory cabinet and can drive up to 40 LEDs.
The N-ANN-I/O and the FACP communicate over a two-wire serial interface employing the ANN-BUS communication for-mat. An additional two wires are used for 24-volt DC power. A single four-conductor unshielded cable may be used for both power and data communications.
Up to eight ANN-BUS devices may be connected to the ANN-BUS of each FACP.

Features

N-ANN-I/O connects to the ANN-BUS terminal on the FACP and requires minimal programming.
Each N-ANN-I/O module drives up to 40 LEDs.
Programmable to indicate activity for points or zones.
Compatible with the NFW-50, SFP-5UD, and SFP-10UD.
Can be remotely located up to 6,000 feet (1,829 m) from the panel.
May be powered by 24 VDC from the host FACP or by remote power supply (requires 24 VDC).
Up to eight ANN-BUS devices may be connected to the ANN-BUS of each FACP.

Agency Listings and Approvals

The listings and approvals below apply to the N-ANN-I/O. In some cases, certain modules may not be listed by certain approval agencies, or listing may be in process. Consult fac-tory for latest listing status.

UL: S635
CSFM: 7120-0028:242
MEA: 442-06-E Vol. 2

The ANN-BUS

POWERING THE DEVICES ON THE ANN-BUS FROM AUXILIARY POWER SUPPLY
ANN-BUS devices can be powered by an auxiliary power sup-ply when available panel power is exceeded. See FACP man-ual for information.

ANN-BUS DEVICE ADDRESSING
Each ANN-BUS device requires a unique address (ID Num-ber) in order to communicate with the FACP. A maximum of eight devices can be connected to the FACP ANN-BUS com-munication circuit. See the FACP manual for more information.

WIRE REQUIREMENTS
The N-ANN-I/O connects to the FACP ANN-BUS communica-tions circuit. To determine the type of wire and the maximum wiring distance, calculate the total worst case current draw for all modules on a single 4-conductor bus. Use the following table to determine the maximum distance the modules can be located from the FACP. In general, the wire length is limited by resistance, but for heavier wire gauges, capacitance is the lim-iting factor. These cases are marked in the chart with an aster-isk (*). Maximum length can never be more than 6,000 feet (1,829 m), regardless of gauge used.
