This was the my second control panel and is currently the one that I have up for the wall system. It is a very nice panel that has a lot of good features for hobbyists such as myself. The only problem that it has is with the Zone 1 disable switch sometimes activating itself (which causes a trouble in the system), but besides that, it is in very good condition. When I first received this panel, it was had only 2 zones, but somebody traded the 4 zone expander module on it to me for some alarms, making it have a total of 6 zones. Also, when I first received this panel, it had a 220/240 VAC to 24 VDC transformer, and it took me a while to track down a suitable 120 VAC to 24 VDC transformer that I could use with it.
