[Honeywell Galaxy G2-20 RF Jam Error]

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
