        RF Door Sensor is made up of two parts: Magnetic Suction Plate and RF Sensor as following Fig.4:

                                  

                                                                                        Fig .4 RF Door Sensor

        Product Usage：

        1) When the detected area is occupied the A/C will remain the status as shown in Fig. 5

                                                                                                             Fig.5

        2) If the door opens and no movement is detected in one minute the PIR will send OFF signal to the A/C. Shown as fig. 6

                                                                                                               Fig.6

        3) If the door closed and no movement is detected in one minute the PIR will send OFF signal to the A/C. Shown as fig. 7

                                                                                                                 Fig.7

If no movement is detected in N minutes the PIR will send OFF signal to the A/C. If there is occupancy during the period the PIR sensor will continue the detecting until auto off the A/C. The system achieves people oriented and auto-control.

        PIR Remote Control has two ways of installation. Please refer to Fig.8 and Fig.9 for details.

        Method one: Drill two holes in the ceiling and fix the housing onto the ceiling using two screws.The switch can be fit into the housing easily. (as shown as Fig.8).

        Method two: Make a hole of 68mm in diameter in the ceiling straighten the spring loaded levers and insert the switch into the hole. The switch can be held against the ceiling. (as shown as Fig.9).

        RF Door Sensor has two ways of installation. Please refer to Fig.10 and Fig.11 for details.

        Method one: Install magnetic suction plate on the top frame of the door and install wireless sensor on the top of the door. When the door is closed sensor and magnetic suction absorb the wireless signal is rapidly transmitted to PIR remote control. When the door is closed sensor and magnetic suction separate the wireless signal is transmitted to PIR remote control. (as shown as Fig.10)

        Method two: Install magnetic suction plate on the of the door frame and install wireless sensor on the broadside of the door. When the door is closed sensor and magnetic suction absorb the wireless signal is rapidly transmitted to PIR remote control. When the door is closed sensor and magnetic suction separate the wireless signal is transmitted to PIR remote control. (as shown as Fig.11)
