Installation
The Click 222 is commonly used with the SmartSensor Matrix and SmartSensor 6-conduc-
tor cable; the steps that follow in this section are specific to this application. If you do not
plan on using the 6-conductor cable, you can skip the steps below and simply wire your
power and communications by following the labels on the screw terminals; in this case, be
aware that you should use the terminals marked 485A and 485B for detection calls.
