I currently have a Wireless Alarm system that runs on 433 Mhz, it’s getting old and beginning to play up so the easiest thing is to replace it with a Wireless one. My question Here in the UK Z-wave runs at 868.42 Mhz, the new alarm panel would run on 868.66 Mhz will I get interference ? is anybody running a Wireless Alarm on 868.66 Mhz and Z-wave ?.
The following is the answer I got from the alarm panel manufacture I was going to use
"We would advise you to contact a professional installer to install the i-on 16. We would also recommend a installer that is NSI or SSAIB registered. If the installer is registered with us he can discuss the i-on 16 technical radio details with us and your installer can also discuss the home automation system radio technical details with the home automation system manufacturer before he installs the i-on 16. " You guessed correct… will not be re-placing my alarm with one of theirs :
Next email was sent to Vesternet z-wave supplier “No, there shouldn’t be any interference. The 868 band has strict regulations governing things like “duty cycle” so a transmission from one system shouldn’t interfere with a different system. I recommend the Visonic as there’s a great plugin for it that integrates it into Vera”
So I am now the owner of a new Visonic alarm panel, bought the basic kit version in case ;D I have had it running now for two weeks with a couple of sensors attached to it, one sits next to a fabrio door sensor, no problems with lights turning on or off by themselves will buy all the sensors now and connect it to an external siren, as it seems there is no interference.
