Receiver for wireless sensors INTERVISION iQ-D-RECEIVER. The receiver for wireless sensors iQ-D-RECEIVER is designed to connect iMPAQ wireless sensors of the iQ series to any wired security panel with NC inputs. The principle of operation is very simple: iQ-D-RECEIVER is equipped with a radio channel receiver and NC transistor outputs. Using conventional wires, the outputs of the receiver are connected to the inputs of the control panel. Thus, the NC outputs of the receiver become an analog of conventional wired sensors for the inputs of the main. When the wireless sensor triggers, it sends a signal to the receiver. The receiver receives it, processes and opens the output corresponding to the sensor. The central, in turn, perceives the opening of the output of the receiver as the opening of the sensor loop and gives an alarm.
