N-ANN-RLY

Relay Module

Annunciators

DN-7107:A1 • K-20

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 #.

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  , ,  and .

• 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 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-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.
