Having problems with this alarm.

two keypads work intermittently, third reads low battery. Third keypad has faint screech. Detectors not detecting?

suggestions much appreciated

Possibly a power supply problem in the main panel, usual suspect is a panel trying to charge a duff back up battery, thus causing a problem with the voltage to keypads and detectors, this situation could damage your panel also if left.

Could also be a damaged/partially shorted cable somewhere, although this I would have thought would blow a fuse, but not always.

Maybe you can post your location and someone on here may be able to help you??
