this is a DSC without encoders or wire. says 1996 V 1.5 when turned on. I have no instruction book to try it out, however if there is a test you would like me to run, and you can get instructions, let me know. I turned it on and scrolled through the functions. everything seems ok.
highest bid by monday morning 6am EST takes it. this is an "as is" product. allow $10 shipping and insurance.
