funny OT story:
when i had mine installed, the guy didn't finish until late (it was already dark). during the test, the simon sends out the x10 signal to cause lamps to turn on and off. well, it just so happend that my pool light was A1 and my Spa light was A2. so during the test, these lights started to flash on and off. i also had a red filter over the pool light and a blue filter over the spa light. so now i have flashing blue and red lights in my back yard. when i pointed this out to the installer, he scratched his head and said "this is only a test. the cops shouldn't be here. why are they in your backyard? " i laughed my a$$ off. i figured it out right away and then tried to explain that it was x10. his response "x-what"
thank you, you may leave.
