Scantronic 9448+ no power or status leds, but leds on keypad

[Tony Park]

Hi all,

 

I've just joined the forum, in the hope I can get some help with our alarm control panel.

 

I'm installing some one automation in our house, and trying to use our hardwired pirs as sensors for triggering events. I've installed 2 fibaro universal sensors in our alarm control panel. I installed the first unit which appears to have been OK, and working as expected. When I installed the second, we developed the strange issue.

 

The battery is about 8 years old, and the control panel was already installed in our house when we bought it 9 years ago. I've replaced the battery, as it was getting rather warm in the box, and causing the transformer to get warm. I've also checked and replaced all the slow and fast fuses.

 

So, the issue is that the vertical line of leds is not lighting at all. The keypad leds show fine,but the keypad does nothing when pressed. The led indicators on the pirs all work fine, turning on when detecting movement, and off again after a second or so, of no movement.

 

I'm wondering if the pvb is dead. Would anyone have any other thoughts?

 

Same happens whether on mains (no battery) or battery (no mains)

 

 

Thanks, in advance

Tony

if it was working before you connected things to it then id disconnect everything but the keypad and see how it is

Hi,

 

I've tried with the original setup, and still seems to be the same situation.

Looks like a new pcb... any idea where to get the same one nice and cheap?

 

Thanks
