Wiring the Relay Module to an FACP

Refer to the following table and illustration for wiring connections.
1. All connections/sources are to be power-limited and supervised.
2. 12 - 18 AWG (0.75 - 3.25 mm
2
) 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.

Setting Relay Module DIP Switches

Each ANN-BUS device requires a unique address. Relay Module DIP switch SW1 is used to set the address for the mod­ule. 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):
