In 2003 we renovated our home and had to have alarm installed in order to get home insurance.
I chose ADT due to their supposedly great service and reputation.

After having to replace many batteries over time, and after replacing them, we had to test the units to enusre they are working properly, our ears flew off from the nasty sound. We finally decided, we need a new system with a less ear numbing alarm sound and after having had problems with their service repair men and scheduling.

Turns out that ADT did not properly install the units especially the heat and fire detectors in the furnace room, and my work studio which has cathedral ceilings and is filled with flamable materials since I design rugs.
They rather placed them on a much lower area since the installer were to lazy to put them were they should belong, on the highest part of the ceivings.

Also, the box with the batterie was placed in the garage, easy for burglars to get a hold of...you name it they did it and all wrong...

The new security company advised us to call the Fire Dept. and to ask for an inspector to come to our home to inspect placements of the individual detectors, to take photos of them and then to sue ADT which we are doing now!

It is irresponsible for a company like ADT to sell and install supposed life saving fire and heat detectors if they do not even care if they are installed properly.

Lucky for us we never had a fire!!!
Today is 9/12/10 and I will keep you all posted of the outcome!
