It is a RF Transmitter Board without case and the Button, Just Input DC3V-DC12V Power for it, It will transmitting Signal, It is a Micro Transmitter Module for Learning Code Receiver. The Transmitter Module can be controlled by Smoke Detector or others Sensor or Microcontroller.Working Voltage: DC3V-DC12V(The Best Voltage is DC9V-DC12V, DC3V Distance will be Shorter)Input DC3V-DC12V for the Receiver, It Transmitting SignalModulation Mode: ASKQuiescent Current: 0uAWorking Current: 8-10 maTransmitting Power: 35-50mWEncoding Type: Learning Code (Ev1527)Transmitting Distance: 100-300mReceiving Sensitivity: 108dBmSize: 21*11*5mm
DC12V 4CH Receiver Board1.Working Voltage: DC12V -/+ 10%

4.Receiver Frequency: 315MHz/433.92MHZ
5.Receiving Sensitivity: -105dB
6.Output State: Switching Value
7.Max Load:10A Relay, Resistive load≤8A,Inductive load≤3A
8.Receiver Board Size:68×48×13mm
9.Case Size:75×55×30mmEncoding Type: Learning Code, Add transmitter by the Learning Button on the receiverOutput State: It is adjusted by the Jumper on the Receiver Board,Momentary----------Jumper on “ M & Mid Pin ”Toggle----------------Jumper “ T & Mid Pin ”Latched--------------Take away the Jumper or put the Jumper on 1 Pin Momentary------------Press the Transmitter button A, the receiver relay A is ON, release button A; the receiver relay A is OFF, the same as B/C/D. 4CH are independent. Toggle---------------Press transmitter button A for 1 time, the receiver relay A is ON, press button A again, the receiver relay A is OFF, the same as B/C/D. 4CH are independent. Latched------------------Press transmitter button A, the receiver relay A is ON, the relay B/C/D is OFF.Press transmitter button B, the receiver relay B is ON, the relay A/C/D is OFF.Press transmitter button C, the receiver relay C is ON, the relay A/B/D is OFFPress transmitter button D, the receiver relay D is ON, the relay A/B/C is OFF. It also mean .Latched only can keep 1CH ON .and it will often have 1CH is ON. Learning Method:
Input power for the Receiver .keep pressing the Learning Button until the Led indicator is ON . Then press transmitter any Button, the Led indicator OFF, then you press any button of the transmitter ,you heard the relay respond ,it mean learning successfully.
Keep pressing the Learning Button on the receiver until the LED indicator from ON to OFF, it mean the code have been cleared successfully.
