Electronic radio transmitters are used to remotely control gates, roller shutters, lighting, arming alarm systems, etc. The remote control system consists of a transmitter and a receiver (relay). There is a possibility of cooperation of many transmitters with one receiver and a single transmitter with many receivers. The RS-N... radio transmitter works with dedicated F&F devices: monostable RS-407M receiver and bistable RS-407B receiver. The impulse caused by pressing the button connected to the transmitter sends the coded signal to the receiver. The transmitter has a protection against breaking the transmission after releasing the button. Thanks to this, even the shortest activation of the function results in the transmission of a full data frame. Data transmission from the transmitter is indicated by the blinking of the red LED. The programming manual (pairing the transmitter with the receiver) is included with the RS-407M and RS-407B receiver.
