Until I swapped the fuses, I had no idea if it was fuses, pcb or cpu. When I spotted the blown keypad fuse, I feared that you may have been right about the pcb, but when I removed the bell fuse, and the bell boxes sounded, I knew that fuse was good, so inserting it in the keypad slot, to see if they were ok, proved it was just a blown fuse and everything was ok, now all I need is to locate a replacement fuse

What you would expect to have happen, the outside bell box, activated until the internal batteries in both of them ran down, and hence why I need to get a fuse to replace the bell fuse

Sorry Peter, youve lost me a bit, when swapping the fuses, the keypad became operational but need to replace the fuse thats vacant for bell fuse

I cut back the damaged cable, and spliced in a replacement section of cable, soldering the ends together before using terminal blocks. I have full confidence in the repaired section

Your right, it wasnt set, and the wires didnt break, they were just exposed by the drill bit, so musta just shorted the keypad fuse

It wasnt armed, cpu is fine as swapped bell fuse to keypad fuse which had blown, and alarm operates fine, just neen to get replacement bell fuse

Norman you were correct, When I checked the keypad fuse it had blown, but when I swapped the bell fuse with keypad fuse, the keypad came back on and the bellbox sounded, so unit is fine, I just need to source a 500mA 20mmx5mm anti-surge, quick blow fuse

Hi all, I'm wondering if I can call on your advice, my ademco accord8 is or was still going strong until whilst doing some diy, I damaged the 8 core cable that goes to the keypads, and also splits off to the upstairs pir and bell box. Ive repaired the damage to the cable, and whilst the main unit still stayed on throughout, the keypads on both doors have remain unpowered. I'm assuming It has blown a fuse to the keypads. But how can I access the main unit without being able to turn the unit into safe mode by using the engineers code (have access to full engineers manual and default codes), without working keypads. Any advice would be gratefully received.
