System Diagnostics Mode
System faults can occur if a PCB in the control panel or one of the repeater panels stops working. This may
be due to a fault condition, loss of power, software lockup or memory checksum error.
A system fault can also occur if the internal PCB confi guration or number of repeater panels has not been
correctly set up in the panel wide programming options (2-1-2-3).
If the fault originates from the control panel’s main PCB then no further interrogation is possible and the
circuit board should be restored or replaced urgently.
The above code has been provided as a quick diagnosis tool to show which additional PCBs, repeater or
network slave panels the control panel thinks it should have according to the programming set up, Vs, the
actual PCBs and repeater/network panels it can see via it’s internal monitoring capacity.
Enter the above code and press ENTER. The control panel will illuminate LEDs to show the set up. The
red, fi re LEDs indicate the confi guration setting. The amber, fault LEDs indicate the presence of the
PCBs, repeaters or network slave panels which the control panel thinks it should have according to the
programming set up.
See table below.
The LEDs will display for 10 seconds and then the panel will automatically exit the diagnosis mode.
Pressing button 2 will reveal the origin of a system fault indication.
Note: After power up, the system should be allowed to initialise for 2 - 3 minutes before using this code
otherwise false indications could occur. If in doubt, re-enter the code a second time to check.
Any differences shown here can then be investigated and corrected either by restoring or replacing PCBs
or correcting the confi guration settings in the panel wide settings mode 2-1-2-3. Pressing button 1 will
show the repeater panel status’s, pressing button 1 again will show the status of the network slave panels.
