The GSM Alarm Smart Power Switch manages remote alarm sensors and communicates with the user via a GSM network standard mobile telephone.

This device is a security center, from which you are able to communicate with the linked device. With the Power Switch itself, the communication can be done via Remote control, SMS commands, phone calls, android / iOS application, and web applications.  
It is plugged in the power outlet and can operate on a  90-250 V, but also comes with a separate CR123A 3 V battery in case of a power blackout. When on battery power, you can not use remote line load functions, but it allows protective security functions. 
Not only has the Power Switch a separate battery, but all the devices that come with it have high-quality batteries, making them independent and reliable. 

It is an exceptional product in itself - but combined with the Motion Detector MD101, the Door/Window Sensor Switch, and Keychain Remote Control that come with the device - it makes a wireless security system that has many advantages:

  • The esthetics will fit in almost any home/office design
  • It can be easily placed in hard to reach locations, at places where a cable system would not be possible to set up
  • Additional components are easily added - like the siren, door/window sensor or additional keychains (up to 6)
  • Should you live in a rented place or decide to move, you can always take your alarm system with you
  • It requires no additional phone lines
Furthermore, the Motion Detector is a passive infrared radio channel motion detector, based on the recognition of temperature changes that come from a person who enters the restricted or protected zone. All that is monitored by the lens on a pyroelectric detector. 
The Door/Window Sensor lets you know if someone opened a door or window. It has a built-in magnetic sensor switch as well as a Temper sensor (if someone tries to disable it) and communicates via a radio channel with the GSM power switch.
Every piece of the equipment can communicate with the user in multiple ways. If the primary mobile phone or any other programmed mobile phone is not available, you can send commands from other devices using passwords.

GSM Alarm Smart Power Switch Feature Focus:

Controlling the commands from a Mobile Phone

The GSM Power Switch can support SMS commands from a mobile phone when it is plugged in an AC power source. 
It also sends a confirmation SMS to the primary registered phone number, but a reply to a balance inquiry will only be sent to the phone from which the command has been made. What that means is that you can send SMS commands from a non-registered phone to the Power Switch, but you will have to add a password. 
The exact procedures of programming the above described can be found in the user manual charts below. 
Example of SMS Notifications from User Manual

Turning the Line Load On/Off via SMS or Keychain

The line load of the Power Switch can be turned on or off via the Remote Control or SMS command. To do that it has to be plugged in in an AC main power source. 
It is simple to use, regardless of the method. For the keychain, it is the button "F", and the light diodes indicate the status - orange/green - on/off. Via SMS you simply send the command and wait for the confirmation message. 
Example of remote control

Panic Button - the Keychain Remote Control can be setup to work as a Panic button device

Default functions of the Keychain Remote Control:
  • Button "A" - Arms the device;
  • Button "B" - Disarms the device;
  • Button "F" - Turns the device voltage line load On/Off.
The Keychain Remote Controls can be registered to the device, by default it is set up to a value of 0.
In order to convert the "A" button to a Panic button an SMS message is sent.
The result will be the following setup of the Keychain RC:
  • Button "A" - "Panic" button
  • Button "B" - Arms/Disarms the device
  • Button "F" - Turns the device voltage line load On/Off.
