GSM REMOTE CONTROL SWITCH, SMS REMOTE CONTROL

The GSM-AUTO is a GSM remote control switch, it connects to the mobile phone network and like a mobile phone has its own telephone number. The GSM-AUTO is activated by calling its 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, 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 a text message.

Applications include the remote control of central heating, lighting, engine pre-heaters, aviation engine heaters, irrigation systems, water well pumps, pumping stations, cabin heaters, resetting & reboot of remote servers and routers, arming and disarming security systems.

GSM Remote Control Switch Features

Two independent relays that can be programmed to switch on for a period of time between 1 second and 18 hours when the unit is called. Two access modes are available, open access where the GSM-AUTO will respond to any incoming call, and secure access where it will only respond to programmed authorised numbers.

Up to 500 authorised user telephone numbers can be added to the white list, when the secure access mode is activated only the numbers in the white list are able to activate the GSM-AUTO. Authorised numbers can be added and deleted as required by sending the unit sms text commands.

The relays can be permanently switched on or off by sending the GSM-AUTO a text message command, a confirmation text can be returned if required.

The relays can be temporarily switched on for a period of time between 1 second and 18 hours by sending the GSM-AUTO a text message command, a confirmation text can be returned when the relays turn on and off if required.

Two relay contacts: with normally open (N.O) and normally closed (N.C) contacts, maximum switching capacity is 10 amps @ 230V ac per relay.
