This auction is going to be for a lot of 3 very nice used Silent Knight Sk-Photo-R smoke dector heads. 

What you see is what you get. They were pulled from a perfectly working system. No bases, no original boxes available.  

Ground shipping will be FREE to anywhere in the lower 48 states. I don't ship anywhere else so please don't bid if you are not in the contiguous 48 states. 

Always be sure to have an authorized fire alarm installer working with you. 

Be mindful that Ebay may charge you tax depending on your location. I have no control over this and I do not have the definitive list of who may or may not get taxed. Please do your due diligence in this matter. 

Shoot me a message if you need to know more, and as always thanks for looking.....
