Dear Sirs !

First, I thank you for helping me get the book you wrote. The book provides information for those who want to learn about fire alarm systems. I hope you continue to write more about fire alarm systems, such as: Common mistakes when connecting wires; Questions and answers about fire alarm systems ... etc. If there are more illustrated pictures then better ... it helps the reader to understand the problem quickly.

Thanks & Brgd, M N
