Until something complicated needs to be done .....

 

But competent diyers don't ask question you have asked above , I think that's what was meant above

The commentator above doesn't know enough about me or my background to pass judgement. As I said, there is nothing complicated about this stuff. It's just a matter of familiarization.

Perhaps your right about judgement,

 

Have you fitted the pirs yet?

Ex  Construction Engineer, Banker, software eng.... blah blah blah

 

But inexperienced in the field of "alarm monkeying"

 

Even with your 2 degrees you made the mistake of employing a "prick end" to "bell up" your cafe... I suspect you didn't use a proper co.

 

The basic function of the alarm movement detector is to detect an intruder within the "protected premise" vandalism of the brick coming though the window isn't an intruder

The PIRs have been fitted for three years. If you read my previous response to other members you will get a better idea of the context. If your'e interested of course. There seems to be surprisingly little in depth information about these sensors on the suppliers' web sites.

Thanks for the input. Are the break glass sensors wall mounted? 

 

Yes, they can be.

Two degrees and a Masters actually. But I'm not the first and I won't be the last to put my faith in an incompetent service provider.

Thanks again although it's probably the brick I need to detect more so than the glass. What do you think?

I'm saying you failed to select a competent service provider

So how will you detect brick flying through air before it hits the window?

 

I not trying to be funny btw

I don't intend to. I can't afford to pay for a force field around the building and NASA won't let me have one for free. So the next best thing is to detect the brick as it enters air space and is flying through the air as it enters the window. It seems reasonable to me that any cold flying objects inside the building during closing hours have come from outside so it's something one should be aware of as soon as possible.
