GE Concord 4 Security System. This was a working panel when I removed it from my home. The keyboards, panel, snap card, transformer and wireless window/door sensors were used in my security system. The remaining items were left over and not used in my house. They are included and untested. If there is a battery involved in ANY of the sensors included, assume it needs to be replaced. Here is a list of the items included. If it is not in the pictures it is not included. 1 - GE Concord 4 Security Wireless/8 Zone Hardwire Security Panel 1 – Eight Zone Expansion Snap Card 3 – ATP 1000 Touchpad/Display 1 – ELK-TRG 1640 Power supply 1 – DSC SD 15W-ULF Wired Siren 1 – FlexGuard FG-1525 Wired Glass Break Detector 7 – ITI Micro Door Wireless Window Sensor (2 new, 5 used) 7 – Sentrol 5414 Wired Glass Break Shock Sensor 3 – Wired System Sensor 2001RFH Smoke Detectors 1 – Wired Motion Detector (unknown brand) 1 – Communication cord I am NOT a security professional, I am just an every day DIYer.
