Hi all this is my first post so please be kind.
I attended a site with a comfort alarm that had started displaying a battery warning and subsequently dialling out to the the client at some god awful times in the morning. The system was installed in 2008 so it seemed like a simple task of sticking in a couple of new batteries hitting reset with a check over of the system and brush off a few cobwebs. However this was not the case.
With the new batteries installed it fails the battery check and with the mains power disconnected after 10-15 seconds the external bell box triggers, ALL LED's on both pcb's extinguish, the keypads go off and so do all of the PIR's. Strange.
So here is what I tested and I hope someone can shed some light on our situation.
2 new fully charged and tested batteries.
Battery 1 = 13.27v no load across terminals 13.27v end of plug for pcb 12.7v steady after 5-10minutes connected to pcb without mains supply
Battery 2= 13.33v no load across terminals 13.33v at end of plug for pcb 11.98v steady after 5-10 minutes connected to pcb without mains supply
Voltage on terminals with mains supply on is around 13.97v on both main and slave board. LP51 and LP52 appear to be ok with no illumination and don't look "burnt out"
Very similar results across the slave board.
Sadly I didn't get the board number but I do recall the inside of the lid stating a cp9000 hopefully this is enough.
Many Thanks in advance. Last edited on Tuesday May 26th, 2015 01:40 pm by slychiu
