Break glass detectors

Not convinced these break glass detectors are worth the hassle.

I struggle to get around 50% of them to activate and most of the ones I do activate only work if I hold the test piece (an electronic break glass simulator resembling a table-tennis raquet) right up against them.

I think I've only ever seen 2 or 3 that I've managed to trip from the extremes of the room, i.e. as far from the detector as possible.

What do the rest of you think...

they dont usually have a range of more than a few meters - maybe the area you are testing needs more detectors.

I always found jiggling your keys is a good way to test them :)

Top tip: if you ever catch fire, try to avoid seeing yourself in the mirror, because i bet thats what REALLY throws you into a panic and dont forget the one thing you cant recycle is wasted time.

QFA and that is what worries me about them and why I dont like them.

The opinions I express are mine and are usually correct!

(Except when I'm wrong)(which I'm not)

I dont think they are something you would fit from choice only if it was an insurance or customer requirement they always seem a bit hit and miss to me with different types of glass behaving in so many different ways frequency wise I would prefere a disclaimer in the spec and at least to have a PIR backing it up!!!!!!.There were only ever one tester per branch when I installed these and no one ever new where it was!!!!so it was a thump on the glass and a rattle of car keys to test them,not exactly compliant I would have thought?.

We never fit them as the only means of detection. Only part of the confirmation for shop fronts etc, with a DT covering down the inside of the window. :)
