What was the 'storm damage' and have panel and expander/psu been replaced?

It is believed that the power lines supplying the property were hit in an electrical storm. The main panel PSU was damaged and the whole Prem 48 unit was replaced. The 8XP in the other building was aparently undamaged but it was replaced by the PSU 200XP as it was tight on capacity for the power supply. I calculated the power supply requirement and checked it against actual load -it is well within the rated capacity for both of the power supplies.

What about keypad(s)?

What about keypad(s)?

Another good question. The system has 3 in total and I dropped a unused spare keypad in place of each of them in turn and it made no difference at all. The situation stays the same. No mains power to the PSU 200XP and all is well, no net errors and no false alarms or messages, put the fuse back in at the spur and back to problems. I'll have a go at investigating the supply.

have I missed the bit where you changed the power supply expander thingy?

Er not sure. Just to try to explain what happened.... The system is installed across 2 buildings. The original install had only one PSU - in the main panel itself, the other building had a 8XP zone expander. During the repairs I changed the expander for the version with its own power supply because the main power supply was actually overloaded during an alarm. It's when the mains power to the expander is on that the probelms appear to begin. Leave it to run on battery power alone for 12hours and seemingly no problem at all hence the main suspect is the power supply.

right, but you havnt changed the new (combined) expander yet ?

start at the start Mark otherwise your just trying to sort a problem that doesnt actually exist, at the risk of setting Arf off on one you must have followed my keypad thread (spurious tampers - turned out it wasnt RFI as tech diagnosed but a crushed cable)

I always assume its equipment first, enviroment later

I'm with you on that idea. I'm going to order in another PSU200 XP and double check the wiring. Thanks for the advice.
