GSM Remote Controller
User Manual
Description:
The GSM-SWITCH is a Single Output Relay system with normally open and closed contacts and provides a
low cost solution for a wide range of applications only requiring a simple GSM Switch, but with a 20 amp
rated Relay on board for switching high currents such as Heating and Lighting circuits and has internal
time clocks that can be programmed in several time zones.
The system has the flexibility to have a separate internal power supply connected on board if required and
therefore can be supplied with or without this facility
A Battery back up on board provides not only an 8 hour continuous of operation of the system but will
send a power down or power restored alerts in the event of power failure.
In addition the GSM-Switch can be ordered with our without an R.F Radio Control Receiver and
Transmitters as required which can mirror the GSM Functions.
As with most GSM Remote systems the unit is activated by calling its cell phone number and the system
will identify the number as authorized and then, will reject the call without answering and switch on the
device connected to it. And therefore there is no call costs involved when controlling the unit via voice call,
only when controlling the system via SMS
The system is able to load up to 250 numbers in the white list as authorized users and the single output
relay can be programmed to switch on for a pre-determined length of time whenever the GSM-SWITCH is
called, alternatively the output relay can be permanently switched on or off by sending the GSM-SWITCH
a text message without effecting the default settings when Called
Alternatively you can program the unit by using the Software programming package supplied with the
system and explained in the separate Soft-ware Manual enclosed.
Requirements:
A mobile phone Network SIM card with sufficient credit to send confirmation text messages when initially
programming the GSM-SWITCH, the unit accepts any Global Network SIM Card as the system is fitted with
a Quad Band Modem.
Power Supply
If the system is not being used with the on board mains Power supply the system will need a Regulated
12 Volt Power supply which has its own input connection on board and separately fused for Protection
.
