Wireless Switch Tutorial

Note: Prior to this tutorial you need to complete setting up the base station receiver and testing the RF Sensor.

This tutorial involves soldering a switch to the RF Sensor button contacts as shown in Figure 1 below.


Figure 1 - Solder your switch to the button contacts

When the contacts are joined (bridged) or separated the sensor will transmit a message indicating the change in state.

Messages transmitted when contacts bridged (switch closed):


Messages transmitted when contacts not bridged (switch open):


Note: In the above example two BUTTONON/OFF messages are sent every time the switch state changes. This is merely precautionary in case one message is missed by the receiver. The number of messages can be configured using the NOMSG command (see sensor manual for more details on that).

Note: You can connect any tactile switch that opens and closes a circuit to the RF sensor. E.g. push button switch (like a door bell), or an on/off switch, a magnetic switch (e.g. for alarm systems), a vibration switch, water sensor etc...

Normally closed switches
If you have a switch with three wires please follow the following guide depending on the color combination you have:

White, Brown, Grey - connect White and Brown to the sensor

White, Black, Brown - connect White and Brown to the sensor

White, White with Red Dot, Brown - connect White with Red Dot and Brown.

Use NC for a door/window that is normally closed, and NO for a door or windows that is normally open. See Figure 3 for how to attach it to the wireless sensor in the normally closed configuration.

Water Sensor

If you bought the water sensor from us you may have received three parts as shown in Figure 5. You do not need the part on the left. Cut off the connector of one side of two of the wires and strip off the shielding so you can solder it to the RF sensor, as shown in Figure 4.

You are almost ready to complete the installation. All you need to do now is place the sensor in the case. Carefully thread the antennae through the hole of the case, as shown in figure 1.Be careful not to pull the antennae as this could cause it to break off.

Figure 5 - Thread antennae through the case

Use the second hole in the case to thread the switch wires through. However I find it easier cut open the second hold so that you can place the sensor in the case without having to thread the switch wires through the hole, as shown in Figure 6.

Now place the sensor in the case as shown in Figure 8.

Lastly fasten the base of the case using the two screws that came with your kit as shown in Figure 9.
