Simplisafe 1st Gen Home Security System Wireless 19 Pieces Keypad Panic Sensors see pic's everything in very nice clean condition. The main unit has battery corrosion but I am sure it could be cleaned and run fine also all other components battery compartments are very clean. You get everything in the pic's, would be great for adding to an existing system so I am selling as parts or repair or replacements parts. Was an operating system until removed from home after sale.
