Make A Simple RF Remote Control Alarm System

We usually install alarm system to help us to monitor the farm. Use infrared motion sensor and light to make a simple security system, for instance. It’s easy to wire and operate. But if the infrared motion sensor is installed at the door of the farm for monitoring, and the light need to be placed inside the farm for warning intrusion. There is a long distance between each other. So the sensor cannot be wired to the light directly. They need a wireless signal to work together at this time.

The long distance rf remote control CB-2N is strongly recommended here. It has two extended wires. With the connection and disconnection of two wires, the remote control can send out a wireless signal “ON” and “OFF”. It pairs with ac rf high power receiver S1PX-AC220-ANT2, which has long range with magnetic mount antenna. Remote control distance of remote control & receiver set is up to 2000m in open field.

Now let’s see how the remote control & receiver set works out.

As seen in the picture, two wires on remote control CB-2N should be connected the contacts of the infrared motion sensor. The output contacts of receiver should be connected to the light.

When someone breaks into the farm, the contacts of sensor are closed; remote control is triggered and then transmits an rf wireless signal “ON” to the receiver. After the receiver receives the signal, output contacts are closed; the light turns on to warn the emergency.

When someone goes out of the farm, the contacts of sensor are cut; remote control is triggered and then transmits an rf wireless signal “OFF” to the receiver. After the receiver receives the signal, output contacts are cut, the light turns off.
