Setting up your DEVICE 

1. Please have 3 new AA batteries for the sensor ready, but do not 

install just yet.

2. Re-Open the APP, go to            Devices section, press          and 

then Start

3. Ensure that the Router SSID is the same that you have just seen 

in your smartphone’s WIFI Settings or you will not be able to pair 

successfully

Setting up your DEVICE 

Go to the locations in the Building where you eventually wish to 

use the Sensor. Look at your smart phone and ensure you have a 

good and steady WIFI connection. Exit the APP, open SETTINGS on 

your smart phone and click WIFI. If you just have a main Router, it 

will be showing its reference (or SSID). However, if you have one or 

more extenders, they may also be showing underneath. 

VERY IMPORTANT

 ‒ The Sensor will only communicate Alarm 

signals to the WIFI Router or Extender that you are about to pair to 

so it is essential that you pair it to the closest/strongest WIFI 

signal/SSID.

Getting started

1. Please check that your smart phone app is updated.  
2. Please also check that your Wi-Fi router is working properly and 

operates on 802.11b/g/n 2.4GHz with WPA/WPA2 encryption. 

We also support OPEN encryption. i.e. no password
