If you decorate in future , a suggestion would be to remove a pir (and you feel competent enough) you could drop the cables out of the 12v AUX terminal in the control panel, carry out the works, then when complete reconnect the 12v+
wait for your fuse to come,
down power your panel - ensure no cables are shorting out
reconnect your PIR
re-fit blown fuse (check all other fuses with a multimeter & if blown change - ensure you replace with correct size)
Power back up, silence alarm & reset
I would change your fuse, there is a possibility that if your code doesn't work the panel may of defaulted back to the default code (quite rare for this to happen but not unknown)
By the looks of your panel it is a CPX
You don't need to test the full house...
If you adding a new circuit to the consumer unit then you would need to carry out a full installation cert for that one circuit you are adding.
If you are adding a spur to say a ring main then you can carry out a minor works cert.
When you next visit maybe worth taking your multimeter to ensure all the voltages the panel is outputting are correct & within tolerance..
If you have a phone line at the property I seem to think you can remote dial into the panel (Like you can on the 595 / 600 panels), that may help you get a better understanding if your such a log distance away
I do know if you are entering a code in one keypad then the other keypad will say System in use...
Its is possible that the keypads may need relearning, I do know on the 595 / 600 / 601 etc you have to learn each keypad (I think from memory you hold yes / no at each keypad and a number is assigned)
Or as what others have suggested, the 800 system is quite old now... Maybe an upgrade may be the best way forward
Sorry but not default or programming information info is given out on here.
If you want to work on the panel yourself you can always contact Pyronix for the manual
But as Al-Yeti says its a very old panel and an upgrade would be a good route to take
Hi, Have you checked you have not blown the Aux fuse?
If you can use a multimeter you could (if competent to do so) test to see if you have 12vdc at the panel aux terminal
Hi, are you saying the pir led is flashing even with no movement in the protected area?
Have you any other pirs on the alarm system? (can you compare the behaviour of this one to the rest?)
I seem to recall the vertias has a three tier service timer one is chime every time when unset, I think the second is one triggered zones when unset & third lockout...
There may be a possibility that the NVM (System memory) has become corrupt, a suggestion would be to have the system defaulted and reprogrammed
The keypad is a gardtec contour keypad (LED)
The panel could be a 500 series (501 / 593) hard to tell without seeing the endstation
It sounds like you have an issue with the control panel back up battery and this may of caused an NVM issue (loosing the system codes / parameters)
When was the last time the system was serviced?
in order to change the engineer code (if unknown) it will mean a full default of the system and would require it being fully re- programmed from scratch.
Unless you are fully ofay with alarms and competent I strongly suggest this is carried out by a competent alarm engineer.
I would suspect a fuse has blown in the panel.
When was the last time the unit was serviced as this would be good time to get a professional in to give it a once over whilst hopefully repairing the system?
