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.

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.
