Is the SecuriLINK the same product as the SafeGuard http://www.marmitek.com/en/product/09604 from Marmitek?
That one is supporting the powerhorn.
I received my SC1200 last Thursday, and am running it alongside my PS561.
I downloaded the Marmitek manual for comparison, it is the same unit adapted to the European market.
I find the Marmitek manual more complete, the images are cleaner and more detailed. They explain the meaning of all the icons in the LCD, i.e. they show all 32 zones and explain the meaning of steady on, slow blinking, fast blinking. The Chime icon is also explained. Their motion sensor has a *slightly* different layout, and they show the position of their tamper switch, which made me check where that switch is located on our units.
One idea I like: you can designate some sensors as emergency sensors, for instance you can set the sensor for a door or window that should never open and the alarm will sound if it opens.
It would be nice if we had an option to clear a specific remote instead of all remotes.
In any case, I feel the SC1200 is a step up from the PS561, with still one glaring omission: no provision for a separate, remote keypad. That should not be too hard for X10 to do, I tested the remote security keypad feature of the Icon Remote and it works, so all is needed is for the engineers to make a dedicated one.
