Table 2: Wiring ANN-RLY Module to FACP

Each ANN-BUS device requires a unique address. ANN-RLY relay module DIP switch SW1 is used to set the address for the annunciator.

A maximum of 8 devices can be connected to the FACP ANN-BUS communication circuit. ANN- BUS device addresses do not need to be sequential and can be set to any number between 01 and 08. Note that 00 is not a valid address. The following illustrates the DIP switch settings for each address (ID Number):

Notes:

1.All connections/sources are to be power-limited and supervised.

2.12 - 18 AWG (0.75 - 3.25 mm2) wire for 24 VDC circuit is acceptable. Refer to the appropriate FACP manual.

3.Power wire distance limitation is set by 1.2 volt maximum line drop from source to end of circuit.

4.Maximum distance from FACP to last ANN- BUS device must not exceed 1,250 feet

(380 m). Refer to Wiring Distance Table in appropriate FACP manual for wire gauge and distance limitations.

5.Common, Normally Closed and Normally Open terminals for each relay follow the same pattern as illustrated above.
