Notes:
 Before connecting the fire control panel to the PC
for the PC programming phase, remove the
jumper of the main board. See Figure 3, item 10.
When the programming phase finishes, replace
the jumper to ensure the Earth fault or Leakage to
Earth is detected.
 To silence the buzzer permanently during
installation, engage the control panel at access
level 3 and remove the Jumper J5. See Figure 3,
item 7. A disabled buzzer causes the zonal LEDs
to flash and a “BUZZER OFF” string displays
alternately with the date and time on the panel
user interface. As a result of this procedure, the
timeout for the installer does not change. To
reactivate the buzzer, replace the Jumper J5 when
the installation process completes.
