Removing Status Units and Ancillary Boards
When status units/ancillary boards are to be removed from the system, the system must be powered down first and the
status units/ancillary boards removed. The system should then be powered. When the system starts it will be in trouble
and the units removed will be shown on the display. Status units are shown as Fux and ancillary boards are shown as
Fox (where x is the address of the unit). The Select button can be used to view all of the status units/ancillary boards
that the system expects to be found but are now missing.
For the system to accept the removal of these devices from its memory the following procedure must be carried out.
If the panel fails to receive messages from a status unit or ancillary board after it has been stored in the configuration
memory, the internal “comms trouble” LED will light and a trouble condition will be displayed on the fascia of the fire
control panel. The seven segment display on the panel will show the number of the unit that is disconnected and all
LEDs on the status unit that is disconnected will flash.
