Problem with new Accenta mini

[derry]

Hi.

 

After installing a new accenta mini today i was ready to power up. connected mains but on connecting battery connections i saw the battery fuse blow.

I checked all wiring, found to be correct and changed the fuse, connected battery and again the fuse blew immediately.

 

I then disconnected all wiring from the system, i.e. bells and detectors, so it was 'as arrived new' and again, replaced battery fuse, powered mains and connected battery and the same thing happened again.

 

I left battery & fuse out and powered up from mains. Alarm seemed to be working ok but i then noticed smoke coming from a resistor above and slightly right to the battery fuse, so i immediately turned off power and now contact you for help on what the problem might be.

Many thanks, Derry.

can you give us details on the battery you used please? You did connect the correct polarity-sensitive battery leads to the right ends didnt you?

 

Check this, check the end of the battery lead that connects to the terminal block on the PCB and see if any copper wire strands are touching anything else.

 

If not you may well have a faulty unit...

I am an electrician of 30+ years of experience and allways use a safe practice of connections, but an obvious question to ask, and for me to check on both pcb's. I also brushed down with a new paint brush just to help insure no stray cable strands contaminating pcb's. Same apply to the battery.

 

My last check was with rkp only connected, battery leads removed from panel, producing same problem.

 

Thank you.

Derry.
