Jim Mac Posted April 26, 2020 Share Posted April 26, 2020 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. Quote Link to comment Share on other sites More sharing options...

PeterJames Posted April 26, 2020 Share Posted April 26, 2020 How did you stop it from sounding in the first place if you chopped the keypad wires? If it never sounded my best guess would be its probably not the keypad fuse, its fried the CPU Quote Link to comment Share on other sites More sharing options...
norman Posted April 26, 2020 Share Posted April 26, 2020 No, it'll most likely just be the fuse. Quote Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...

norman Posted April 26, 2020 Share Posted April 26, 2020 Why would it sound if a fuse popped when unset? Quote Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...
Jim Mac Posted April 26, 2020 Author Share Posted April 26, 2020 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 Quote Link to comment Share on other sites More sharing options...

norman Posted April 26, 2020 Share Posted April 26, 2020 If possible I'd look to make sure that the cable is not going to short again. If you've damaged it with the drill and are confident enough I'd look at maybe putting a junction box in where the damage is but you'd need to isolate the whole cable from the panel before doing it.
