Powering Ann-Bus Devices From Auxiliary Power Supply; Ann-Bus Device Addressing - Honeywell Fire-Lite Alarms MS-9050UD Manual

1.9.1.3 Powering ANN-BUS Devices from Auxiliary Power Supply

Figure 1.3 illustrates the powering of ANN-BUS devices from an auxiliary power supply such
as the FCPS-24FS6/8, when the maximum number of ANN-BUS devices exceeds the ANN-
BUS power requirements.

1.9.2 ANN-BUS Device Addressing

Each ANN-BUS device requires a unique address (ID Number) in order to communicate with the
FACP. A 5-position DIP switch on each device is used to set this address. The address set for these
devices must also be programmed at the FACP for the specific device (refer to the programming
section titled "ANN-BUS" on page 106).
A maximum of 8 devices can be connected to the FACP ANN-BUS communication circuit. 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 table shows the DIP switch setting for each address.
Note: Switch 5 must be set to OFF for ANN-BUS devices to be recognized.
