Technical Description AAU 1736 – Rev 1 Table 2 Push Buttons: Push button Colour Operation / function Used, when LED "L2" is turned on, to scroll through the queued alarms. (The first alarm Alarms queued Black will automatically be shown again after 20 seconds, if no button is used during that time.) Used to acknowledge an AA alarm.
AAU 1736 – Rev 1 SW mode & Address setting Alert Annunciation Unit 1736 can run in SW mode 1736 - 1587 only. It shall also have a unique address on the RS485 line connected to the 1587 board in the FT512 C.I.E.
Technical Description AAU 1736 – Rev 1 6.1.1 SW mode setting via jumper "J4" An AA unit in operation will be ready for the "SW mode setting" via the jumper "J4" in the unit. Shunt jumper link "J4" momentarily. When the AA unit is ready for the "SW mode setting" this is indicated by LED "L2"...

Technical Description AAU 1736 – Rev 1 User definable text messages (alarm texts) In the C.I.E., each alarm point (zone – address) and each zone can have an individual user definable text message (alarm text) presented in the display by fire alarm, see the Technical and Operation Manuals for the system respectively.
Technical Description AAU 1736 – Rev 1 Commissioning of a new unit / SSD download The cable (RS485 line) to the AA unit(s) shall be connected. See connection diagram for the system respectively. In the FT512 C.I.E. the 1587 board shall be mounted. Remove the fuse "F1" on the 1587 board.

Technical Description AAU 1736 – Rev 1 There will also be a fault message in the C.I.E.: In system FT512: "FAULT: SSD, AAU xx, 1587 board x, CU xx". In system FT128: "FAULT: Site specific data (SSD), AAU x. In system FT512 G3: "FAULT: Site specific data, alert annunciation unit ##, control unit ##"...
Technical Description AAU 1736 – Rev 1 Fault messages Here follows a list of the fault messages that might be displayed in the AA unit and in the C.I.E. respectively. 10.1 Fault messages in the AA unit "No contact with control unit" The contact with the C.I.E.
Technical Description AAU 1736 – Rev 1 10.2.2 System FT128 "FAULT: No reply AAU x. The contact with the AA unit is interrupted. Check the cable and all connections. Is a correct / complete SSD download (via Win128) performed? Check the address setting, SW mode setting, etc. See also chapter "Restart", page 19.
Technical Description AAU 1736 – Rev 1 Software (SW) The software is stored in a flash memory in each AA unit. This software can be replaced / updated (i.e. downloaded via Win512 / Win128 / WinG3). All units connected to the same RS485 line must have the same SW version and it is highly recommended to have the same SW version in all the display units in the system.
Technical Description AAU 1736 – Rev 1 Continue from 3 above: or press black push button ("P1") and the SSD will be erased (Erasing SSD..). The AA unit will restart (Restarting..), i.e. the buzzer will sound for approx. two seconds and the unit will return to normal operation.
