The 4WT-B will work with all security systems, and should be used if you will have more than just a few or have more than one level. The 4WT-B also has a built in 135 degree heat detector. Four wire smoke detectors get wired to a zone, which will allow you to see where the detection is taking place unlike the two wire smoke detector, that will just let you know that smoke has been detected, just not where. |
