Sending Play Command After House Alarm Activated

Hi,

I'm looking to integrate my SONOS system so that when my alarm is activated a specific track or playlist is started and played throughout all zones of the house. The alarm system at present sends a signal to my lighting system which then can send out a telnet request to any device on the network.

So my query is how to send a request via telnet to the sonos system to do what I want? I have looked at SonosWeb but do not want to run this on a PC or MAC. I have a synology NAS but have been unable to find any info on running SonosWeb on this.

Any help appreciated.
