At Last we have what you have been asking us for!

This GSM unit not only works with our own alarm systems, but also works with insurance approved alarm systems too!

We are pleased to offer an add on GSM module. This means no longer do you have to site the alarm system by a telephone socket, in fact you do not even need a telephone line in the house, garage, office, stable or out-building. To enable this GSM module to function your existing alarm will need to be an auto dial system already, as this module just acts as a line for your system to dial out from. If your alarm system sends text message, this device will pass them on.

Just connect the house alarm telephone lead into the GSM module, connect the antenna, add a mobile phone SIM card plug in the power supply and the system is ready.

It could not be any easier than this. Please ensure that the mobile phone SIM card provider has a signal in your area. If your mobile phone works from home then we recommend that you buy the same providers 'pay as you go' SIM card.

You do not need to sign up to anything, or subscribe to a provider, just purchase a 'pay as you go' SIM card
