alarm ,control touch spots are connecting when there is a alarm).When connecting alarm sensor, touch
spots of sensors should connect with -2 2K resistance in parallel(Figure 1).When connecting resistance,
.
should connect terminal of touch spots which is near sensor.Ports of each group sensor can connect
with multiple same sensors to monitor multiple places,method is: Touch spots of Alarm sensor are
connected in parallel (figure 2) No matter how many sensors are connected in same group,just need
