Notifier 3030 - Style 6 Neg Loop 4 problem

[Framingham]

Hello

Have a problem that keeps on happening on a Notifier 3030. Style 6 negitive loop 4. open circuit does not clear even if jumpered on two terminals on negitive side. Have removed some devices and still trouble. Software is all up today

Any suggestion on this trouble.

Thanks

Replace the LCM, loop control module.

I have seen that before and all I can say is good luck if the cpu is an older one...They updated the card with new firmware and unless you have matching firmware in the loop controllers you will see mismatch errors.


Good luck

Software was updated. This problem just occoured when construction happened and panel had high vibritions panel. New card and Software updated at that time. Problem clears and then after couple week comes back.

Is there any trouble shooting guide for this panel?

Thanks
