ANN-BUS Devices

2.9.2 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 96).

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.

When installed and enabled through FACP programming, the ANN-LC will always be set to
address 08. No dip switch settings are used to set the address on the ANN-LC.

2.9.3 ANN-80(C) Remote Fire Annunciator/Indicator

The ANN-80(C) Annunciator/Indicator is a compact, 80 character, backlit LCD remote fire annun-
ciator 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 a
button for Reset, Silence, Acknowledge, and Drill. The ANN-80C does not provide these buttons.
Communication between the ANN-80(C) and FACP is accomplished over a two wire serial inter-
face employing the ANN-BUS communication format. The devices are powered, via two addi-
tional wires, from either the host FACP or remote UL-listed, filtered, power supply.
