SIMON 3 HOME SECURITY SYSTEM

Option "05" Use Secondary phone number. It works every time for me.

Okay!!!!! Got it working properly. What I wound up doing is setting it back to factory defaults by unplugging it and disconnecting the battery at the same time as holding down the cancel,clock set, and minutes +, buttons simultaneously. Likewise, when connecting the battery leads you have to hold down the same three buttons. Then you have to teach the Simon 3 the sensors (page 7 of the installation book). Simple ONCE you figure it out and then it makes sense. My thinking is that Mr. Lightening may have struck nearby my apartment and fouled up the system. Thanks JohnCHS for your input. I put my telephone number on my cell phone as both the primary and the secondary number to call.( option 4 and option 5) Hope this helps someone if they have a similar problem.
