Honeywell Lyric Alarm System And 5800 Sensor RF Problems

Has anyone else had issues with RF Signal Loss on 5800 series sensors with a Lyric panel? I have a customer who wanted recessed door contacts so we went with 5818MNL as Lyric does not have a SiX recessed contact. All of the motions are Six series. Everything installed as normal and worked fine for about three months. Now, they keep getting RF Signal Loss reports randomly from each of the 5818MNL recessed door contacts. I have done the Go-no-Go test and as of today the sensors all check out during the test but I know that sometime in the near future there will be another problem. Tech support believes that something is interfering with the signal near the range of the 5818's. I can not convince the customer of this, and they really don't care as to what is causing the problem... they just want it fixed. The catch is that they REFUSE to use a surface mounted contact. Any suggestions on a solution or troubleshooting tips?
