hi guys, just wondering how other engineers test break glass detectors, ive found it to be a right pain in the **** trying to get them to get open circult, i usaully dangle keys, which works but doesnt look very proffesional. there must be a easier way of doing it. Masterblasters do set them off, because i had a job that anytime the customer had a false alarm the masterblaster would activate all the break glasses causing a confirmed signal, obviously i wont be testing with a masterblaster,,,

how do you test them

With one of these

Failing that, put the window through

that and keys for me

Before I found a proper tester I used to thump the glass, so I got the low level flex, followed by the quick key jangle.

Using the tester is far better as its always the same volume and so a more uniform test.

Just a thought,

Would a recording of breaking glass on my phone work?

Like this mp3 recording

Possibly because it is listening for an exact frequency

Guess it would depend on the volume

We don't fit many at all but will try it the next time i have a site with them.

Great if it works, saves another tester you need.

we are using Honeywell FG701 which can voice and trigger the break glass detector.

I usually have trouble using my Honeywell BGU Tester on our new Texecom Impaq BGU's. Very rarely will trigger.

You look an idiot after 4 or 5 goes with the tester. Especially when you have to resort back to the thump and van keys technique.

Works perfect on Honeywell BGU's tho, certain testers seem to only work with certain BGU's.

Generally avoid fitting BGU's, have fun with "false alrms" around fireworks season.
