I've installed my G2-44 panel and have added the RF Portal to it successfully. I've managed to add two wireless door contacts which work as they should. However, I'm having issues with the IR800M and IRPI800M wireless detectors. I've only got four of them and can get the panel to identify the serial numbers. The problem starts after they've been left for a while and I try and set the panel and then trigger them or do a walk test. The LEDs flash quickly and the panel doesn't respond when movement is made. When you go through the learning procedure again, it settles after a few minutes and you trigger the panel/walk test they respond. Any longer than a few minutes and they don't respond. I've tried the the 'older' RF portal with the wire antenna, and the newer version that has the 3 LEDs and the antenna built into the PCB but there is no difference. Would the batteries in the PIRs make any difference? Also there is a wireless extender for my internet hub in one of the rooms. If anyone can help I'd be very grateful.
