4-channel receiver 433 MHz, EV1527. Smart Stairway RFM-Ev1527-4 (Product code: )

The 433MHz, 4-channel receiver with 3.3-5V DC power is designed for use with two corresponding wireless motion sensors with channels "A" and "B", and (or) with 2 wireless switches without fixation with channels "C" and "D" respectively. You can use any number of channels you need, 1,2,3 or all 4. The receiver works with EV1527 encoding, so it allows you to use any transmitters, radio buttons and consoles with such encoding. You can program it to duplicate devices, radio remote controls, etc., the receiver has 12 memory cells and can remember up to 12 devices. To connect it to the SmartStairway SS-xxxxx series controller, connect a red power wire with the output of the "+5V" controller, a black wire with the "-V GND" terminal. White wire with the input of the upper sensor ("Channel A"), yellow with the input of the lower sensor ("Channel B"), orange with the input of the upper button ("Channel C"), green with the input of the lower button ("Channel D"). If you use a smaller number of channels, just isolate the unused wire and do not connect it to the controller. Position the receiver so that the metal cabinet or structures do not interfere with reception, do not use the receiver inside the metal cabinets. This wireless module expands the capabilities of controllers to activate backlight using any devices compatible with the EV1527 encoding protocol operating in the 433 MHz range.

Attention. Be careful when connecting. The receiver is designed for 3.3-5V power supply. Connecting to a higher voltage source will damage the receiver. Connect only to the "+5V" controller terminal. Do not confuse polarity, be careful.
