N-ANN-RLY
Relay Module
General
The N-ANN-RLY relay module provides 10 programmable Form-C relays when used with a compatible FACP (Fire Alarm Control Panel). The N-ANN-RLY module may be mounted inside the FACP main circuit board chassis or in the battery area of the enclosure using optional mounting bracket P/N: ANN-MBRLY. Reference Installation Instructions document #53318.
The N-ANN-RLY 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-RLY connects to the ANN-BUS terminal on the FACP and requires minimal programming.
•Provides 10 programmable Form-C relays.
•Ten Form-C relays can be programmed for various func- tions; Alarm, Trouble, Supervisory, AC Loss, Waterflow Delay, Input Zones and Silenceable Alarm.
•Compatible with the FireWarden 50, SFP-5UD, RP-2001, RP-2002 and SFP-10UD.
•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.
•Listed to UL Standard 864, 9th Edition.

The ANN-BUS
POWERING THE DEVICES ON THE ANN-BUS FROM AUXILIARY POWER SUPPLYANN-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 ADDRESSINGEach 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 REQUIREMENTSThe N-ANN-RLY 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 table on the following page to determine the maximum distance the mod- ules can be located from the FACP. In general, the wire length is limited by resistance, but for heavier wire gauges, capaci- tance is the limiting factor. These cases are marked in the chart with an asterisk (*). Maximum length can never be more than 6,000 feet (1,800 m), regardless of gauge used.
Refer to the appropriate FACP manual for wiring details.Ordering Information
