Hello,

 

We have had a Scantronic 9448+ for a while. It was installed in the house when we moved in. It has been working fine and only needed little attention over the years. I changed the battery and about 6 years ago we had a PIR changed.

 

Recently the alarm played up. The alarm triggered when we set it almost immediately. I checked the log with 8 - enter - code and it indicated one faulty zone - actually with the recently changed PIR - and I ordered a new PIR. As the older ones are Risco I ordered a Risco iWISEBus. The PCB is different but I thought it should work....

 

In the process of changing the PIR I triggered the alarm a few times when wires were touching. Once the new Risco was wired up I could not arm the alarm any more. The panel is showing the tamper LED and when I key in the code I can hear a beep.

 

I have not opened the main panel yet.

I have attached a picture of the wired in Risco iWISEBus.

 

Can anyone help please. Why should the alarm start showing the tamper LED constantly after alarms have been triggered?

Isn't the iwise bus a bus detector that will only work on a risco panel? 

You have also probably blown the fuse or panel. Wires shouldn't 'touch'

QFA Bus detectors or ID detectors from a different brand will not work
