ANN-BUS Devices Installation
2.7.2 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 73).
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.
2.7.3 ANN-80 Remote LCD Annunciator
The ANN-80 LCD Annunciator 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. Communication between the ANN-80 and
FACP is accomplished over a two wire serial interface employing the ANN-BUS communication
format. The devices are powered, via two additional wires, from either the host FACP or remote
UL-listed, filtered, power supply.
Specifications
• Operating Voltage Range: 18 VDC to 28 VDC
• Current Consumption @ 24 VDC nominal (filtered and nonresettable):
 Normal/Standby (no activity): 37.0 mA
 Trouble: 39.0 mA
 Alarm: 40.0 mA
 AC Fail (not backlit): 15.0 mA
• For use indoors in a dry location
Installation
Ensure that all power (AC and DC) has been removed from the FACP before installing the
annunciator.
 Mounting
The ANN-80 can be surface mounted using the optional ANN-SB80KIT-R (red) or
ANN-SB80KIT-W (white) surface mounting box or semi-flush mounted to a single, double or 4”
square electrical box. Select and remove the appropriate knockout(s), pull the necessary wires
through the knockouts and mount the annunciator in or on the wall depending on the type of
installation desired.
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.
