Jim, I have both types.....they type that is active while I'm home (both manually activated by either SIG, CZ or my alarm system) and away. I my builder install all the sensors when I built my house about 5 years ago.....them had a local alarm company install the rest of it when the house was finished.....its all monitored for both break in and fire. the cost....I pay $85/qtr ($349/yr).
