Ah, just wondered, and yes it's a good idea if it lasts.

I would recommend the Visonic Powermax, very easy to install and easy to navigate the menu system. The powermax also comes as a quick fit kit with the detectors already learnt onto the system. Great coverage too!

I am looking at Visonic Powermax. Should i wire the external sounder or use the wireless sounder that runs power on the battery

Wired sounder should be way to go 

powermax is 1way wireless though

For the avoidance of doubt, OP, this is bad.

Although, bad is not really a word I would use, lets put this into prospective. There are certain vulnerabilities to one way wireless, but with all security systems the total risk should be considered. If your property is likely to be of interest to professional burglars then this type of system would not be suitable. But I suspect if you had this sort of risk you would not be DIYing and certainly would not be asking questions about security on a public forum. Assuming that you just want to deter the local druggies/opportunist that would not have the first clue about security systems or their vulnerabilities then the powermax would be suitable.  

+1, it's all about the level of risk you wish to address. 

 

 

Disagree that one way is poor only because of risk.

i dont agree, using 1 way when 2 way is available is daft regardless of risk. Would you still use a pressure mat or a pir?
