Hi Crash,

Not sure if this is it but on some older panels I've seen a problem
responding to RF remotes when the siren was active.  It turned out to be a
power problem.  The siren would draw so much current that the voltage
available at the receiver was dropping.  You can check to see if this is
happening by testing the voltage at the receiver with and without siren.
It's a long shot but it's easy enough to check.  If that does turn out to be
the problem you can offload the siren(s) from the panel power supply with a
relay wired directly to the battery.

Frank would remind you if I didn't to run the power through an inline fuse.
:^)
