8. Troubleshooting
In order to detect problem and solve it please follow these instructions. In case that your problem is not
described, contact your sales representative for assistance.
For easier check up of system front cover of power supply module can be removed. Pls. check bellow
overview of power supply module PCB.
Power failure alarm
Due to batteries inside main unit power failure alarm can be indicated without any of other equipment
connected to main unit. In order to determine fault in system power supply pls. follow steps bellow.
1. Check power supply to power supply module
2. Check connection between main unit and power supply unit
3. Check fuse 1AF on main unit
4. Remove front cover of power supply module
5. Measure 19V DC voltage between TP1 and TP-
6. Check fuse F2 on power supply module
7. Check fuse F1 on power supply module
Important!!!
In case of power failure alarm lights need to be acctivated manually and their operation needs to be checked
visually. Light power supply need to be present!!!
Note!!!
Above steps do not cover lost of power supply 230VAC to input modules. Lost of 230V AC to input modules will
be indicated on display as lamp failure when lamp wants to be acctivated.

Main unit communicates with input modules via communication bus. Irregularity in some module can affect
communication with other modules. In this case failured module needs to be detected.
