GSM REMOTE CONTROL SWITCH

 

order

The GSM-AUTO is a GSM remote control switch, it connects to the cell phone network and like a cell phone has its own cell phone number. The GSM-AUTO is activated by calling its cell phone number, it will recognise an authorised telephone number calling it, reject the call without answering and switch on or off the device connected to it, because it rejects the call without answering there are no call costs incurred.

It has 2 independent relay switches with normally open and normally closed switch contacts, these can be programmed to switch on for a pre-determined length of time whenever the GSM-AUTO is called.

The relay switches can also be temporarily or permanently switched on or off by sending the GSM-AUTO a sms text message command. It can report the relay status by sending back a text message.
