Question: does this unit fit without any drilling/modifications
Document: Buying this product here saved me over two hundred dollars from the cost of an alarm company. And this is the exact same unit.
The unit itself is fine but there was no color coded wiring diagram with it, just a very complicated set of instructions. All they needed to do is tell the installer which color of wire goes on what terminal.
Bought this item to replace an existing unit that was twelve years old that was installed when the house was built. It was a very easy remove the old unit and install the new. Very good quality item.

This was a true plug & play replacement for an old one that was damaged by a water leak. Very easy to replace.

My old model was malfunctional at mid night, the alarm wake all my family.I looks for the vendor's catalog, it is replaced by this model.The price seems a little bit high, but it comes with installtion diagram. So, I can replace my old one and reset my home security system. Everything is OK now.
Great smoke detector. Works with the Silent Knight SK-5208 Fire alarm panel. Cant comment on how it works in a fire, and hopefully wont have to find out! It does work perfectly if you test it with a fog machine
A faulty smoke detector triggered my alarm system. I checked everything and there was no smoke,steam,dust or even a spider that could have triggered it...twice in ten minutes and it would not reset. I took it down and searched for a similar model and the same make with a two wire configuration. the end of line resistor broke when I tried to  remove it so I bought a 5 pack at Radio Shack for $1.25. The installation was easy. Just read the instructions.
Answer: no
