Retrieving Motion Detector by 1 Channel 12V Radio Module

Question from customer:

I want a kit radio module 1 channel (12V), can transmit the state of a dry contact input (on transmitter). This is to retrieve the status of a motion detector. Distance 60m open field.

Answer:

We recommend 1 channel 12V rf receiver and transmitter with dry contactinput (S1L-DC12-ANT2 & CB-2N). The very special design is its transmitter with a dry contact input aside. The triggering method of this transmitter is connection of two wires on it. There is only one channel at that relay on the receiver. The output contacts of relay are normally open and closed. Working distance of transmitter and receiver with external extend antenna are 2000M / 6000ft (theoretically).

 

 

Wiring:

Wires on the transmitter should be connected to the contacts of motion detector (original device).

The normally open contacts B&C of receiver should be connected to the device being controlled.

Maybe you can wire a lamp to the receiver. We offer three voltage versions for receiver: 9V, 12V and 24V. You can choose the right one according to the voltage of device being controlled.

 

 

Operation:

When the motion detector (original device) is triggered and begin to work, the transmitter is also triggered and then transmits an rf signal “ON” to the receiver. After the receiver receives the signal, contacts B&C are closed; the lamp being controlled will be turn on.

When the motion detector (original device) is not triggered and stop working, the transmitter is also triggered and then transmits an rf signal “OFF” to the receiver. After the receiver receives the signal, contacts B&C are cut; the lamp being controlled will be turn off.

 

Note:

The output contacts of motion detector should be normally open / normally closed.

Buttons on the remote are only used for test.

The big button is for testing “ON” signal. The small button is for testing “OFF” signal.
