Make sure you call the fire station or Grand Alarms right away to avoid any unnecessary emergency dispatches. Otherwise, they are pretty careful in terms of following up with you.
I want to tell you a huge thanks for installation new alarm system at my home. In several months after your work everything works like it's new, even there are kids at out home=)) THANK YOU
Considering that the work is not difficult and fast, everything is OK. The job was done quickly, as promised. They know their business. I recommend them for cooperation to my colleagues and friends.
