The Radio Shack used two security lamp addresses. Like if you picked B1. B2 was also a security lamp address.
During an alarm it would send B1 B2 Bon then B1 B2 Boff. The power horns did not like that.
I did see on page 35 of the manual. The two security light codes detailed. Sounds just like the Radio Shack model.
Guess we wait for someone to report findings when they get the console or a complete kit.
Not going to be the Brian H testing labs this time.
