17.1 Fault Messages
Below follows a list of all fault messages, in alphabetical order. There is also an
explanation to each fault.
Checksum fault in downloaded data.
Control unit will now restart
A fault in the downloaded Site Specific Data (SSD). After the restart a
new fault will be generated:
FAULT: Site Specific Data (SSD), Control Unit xx.
A new SSD download will probably solve the problem.
FAULT: 24V for external equipment output x,
Control Unit xx
x = Power supply output 1-4 (J3:5-12). xx = 00-29.
Check fuse F9, F10, F11 and F12 respectively on the Main board 5010
in Control Unit no. xx. Fuse: T4A L 250V (TR5).
FAULT: 24V for routing equipment,
Control Unit xx
Power supply output 0 (J3:3-4). xx = 00-29.
Check fuse F8 on the main board 5010 in Control Unit no. xx.
Also indicated by LED Fault / Disablement "Fire brigade TX" (L12)
blinking. Fuse: T500mA L 250V (TR5).
FAULT: 24V out, output unit xxxxxx
This is valid for the external power supply 3366 connected on the COM
loop. The output might be turned off or the current output limit (4A) is
FAULT: Alert annunciation unit xx,
Control Unit xx
1736 (Alert Annunciation Unit - AAU.)
The AAU unit xx, connected to Control Unit no. xx, is programmed as
another type in the SSD or a fault in the unit.
FAULT: Battery not connected,
Control Unit xx
• Battery voltage is below 18.9 V.
• Batteries (2 x 12 V) are missing or not connected correctly.

This check is done every 14
th
minute but when the fault is generated the
check is done every 30
th
sec. Fuse: T6.3A H 250V (5x20 mm
FAULT: Battery, technical number xxxxxx
