FAULT: Loop unit techn. address xxx
The communication with the unit is not all right, i.e. the unit is out of
order / faulty.
For detector types 33xx / 43xx (in NORMAL mode): The built-in self
verification function has reported a fault status.
FAULT: Low battery capacity
th
Every 4 hour the battery circuit (connection cables, fuses, etc.)
resistance is checked. A resistance over 1.4 ohm will generate a fault
In the New Zealand convention: The battery charging is turned off 60
th
minutes every 24 hour. A battery voltage < 24.4 V during these 60
minutes will generate a fault.
If a fault is generated it will automatically be Serviced after these 60
minutes.
FAULT: Low voltage
System voltage < 21 V DC.
FAULT: Low voltage, techn address xxx
This is valid for an external power supply (e.g. 3366) connected on the
COM loop. The power output is turned off because the unit's internal
voltage is < 19 V DC.
FAULT: Mains
 Loss of mains, i.e. no 230 V AC (the fault is activated after
1-300 minutes).
 Fuse for 230 V AC blown.
 Fuse "F1" on the main board 4556 blown.
FAULT: Mains, external power supply
Loss of mains, i.e. no 230 V AC to the ext. power supply equipment
(the fault is activated after 1-300 minutes).
A fault output is connected to a programmable input in the EBL128
system. Check the input as well.
