Figure 6: Call function
The device is able to store a list of phone numbers with their relevant names (max 300) that are authorized to activate and/or
deactivate the relay output 1 with a simple phone ring at no cost. The device detects the incoming call and immediately hangs
up, activating at the same time the system it is connected to.
This function can be set through the following modes:

Exchange : simple relay exchange is done (ON/OFF)

Pulse : a programmable pulse of 1 up to 65535 seconds (ca. 18 hours) is performed
The user can also activate the SMS feedback option (replying SMS) allowing the reception of an SMS confirming the system
status on the mobile phone from which the phone ring was made.
The PULSE mode also allows customizing the SMS that confirms the command execution.
