Powering ANN-BUS Devices from Auxiliary Power Supply

Figure 2.21 illustrates the powering of ANN-BUS devices from an auxiliary power supply such as the FCPS-24FS6/8, when the maxi-
mum number of ANN-BUS devices exceeds the ANN-BUS power requirements.
2.8.2 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 71).
A maximum of 8 devices can be connected to the FACP ANN-BUS communication circuit. Device addresses do not need to be sequen-
tial 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 set-
ting for each address.
NOTE: address (ID Number) DIP switches on some devices may have more than 5 switch positions. Unless otherwise specified in the
documentation supplied with each device, switch positions 6 and above must be set to OFF.
2.8.3 ANN-80(C) Remote Fire Annunciator/Indicator
The ANN-80(C) Annunciator/Indicator is a compact, 80 character, backlit LCD remote fire annunciator which mimics the FACP display.
It also provides system status indicators for AC Power, Alarm, Trouble, Supervisory and Alarm Silenced conditions. The ANN-80
Annunciator provides buttons for remote Reset, Silence, Acknowledge, and Drill of the FACP. The ANN-80C Indicator does not provide
