What type of relay needed

[cctv]

Hello all, I am installing 3 pir wirless sensors which when triggerd by movement send a rf signal back to a mains plug type reciever unit that emits a tone and can switch on a lamp or other electrical devise when triggerd by movement of pir sensors,My question is, I want the 220v mains addaptor to be conected to a relay switch that in turn is connected to a gsm mobile phone so that when pir sensors are triggerd the mains addaptor will switch relay to dial mobile gsm phone which is set to ring on speed dial, can anyone recomend type of relay for this instalation along with wiring diagrame from mains addaptor to relay switch and back to gsm mobile phone, I tried various sites for info to no avail, any help or advise on this project would be greatly appriciated.

A 5V SPST relay should be enough, how are you conneting the relay to the phone?

try a plug pack of around 6V to power the relay.
