Hi, 8 years ago I installed a Honeywell Galaxy G2-20 (including a RIO and a couple of wireless PIRs) and have enjoyed faultless service from it until recently. I now regularly (3 or 4 times a day) get an RF Jam error. Any ideas what the cause could be and what I can do about it? I've read the manual and other than configuring the 'stop set' to allow you to set the alarm with the fault condition unacknowledged I can't see any settings which might help Thanks in advance, Binney
