ZCTR04 is a indicator can be matched with  ZCT100AL series 1-axis tilt sensor and used for display the current output angle value. 

The alarm angle can be set by user accordingly. When the angle returned is bigger than the alarm angle ,ZCTR04 will alarm with lighting and at the same time the relay inside closed and the external circuit is triggered to control.
