MRP-2002 Series Instruction Manual — P/N 53049:E5 7/28/2016 39ANN-BUS Devices Installation2.7.2 ANN-BUS Device AddressingEach ANN-BUS device requires a unique address (ID Number) in order to communicate with theFACP. A 5-position DIP switch on each device is used to set this address. The address set for thesedevices must also be programmed at the FACP for the specific device (refer to the programmingsection titled Section 3.5.7, “ANN-BUS”, on page 70).A maximum of 8 devices can be connected to the FACP ANN-BUS communication circuit. Deviceaddresses do not need to be sequential and can be set to any number between 01 and 08. Note that00 is not a valid address. The following table shows the DIP switch setting for each address.2.7.3 ANN-80 Remote LCD AnnunciatorThe ANN-80 LCD Annunciator is a compact, 80 character, backlit LCD remote fire annunciatorwhich 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 andFACP is accomplished over a two wire serial interface employing the ANN-BUS communicationformat. The devices are powered, via two additional wires, from either the host FACP or remoteUL-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 locationInstallationEnsure that all power (AC and DC) has been removed from the FACP before installing the annunci-ator. MountingThe ANN-80 can be surface mounted using the optional ANN-SB80KIT-R (red) orANN-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 wiresthrough the knockouts and mount the annunciator in or on the wall depending on the type of instal-lation desired.NOTE: Address (ID Number) DIP switches on some devices may have more than 5 switchpositions. Unless otherwise specified in the documentation supplied with each device, switchpositions 6 and above must be set to OFF.Address Switch 5 Switch 4 Switch 3 Switch 2 Switch 1not valid OFF OFF OFF OFF OFF01 OFF OFF OFF OFF ON02 OFF OFF OFF ON OFF03 OFF OFF OFF ON ON04 OFF OFF ON OFF OFF05 OFF OFF ON OFF ON06 OFF OFF ON ON OFF07 OFF OFF ON ON ON08 OFF ON OFF OFF OFF
