I have an issue with a Guardall P48i ( PX48i ). It has all the elements ( detectors ) addressable and a couple of them just fail to operate. My problem is that the system can't be armed with open zones. i don't have any documentation about this system, neither engineer manual ( programing ) nor connection software. I have found something on net: user manual & installation manual but says nothing about how to program the system. Any kind of help is appreciated.
All good,
Lucian I
