Thanks for the info antinode looks like flexguard it is.

 

I was searching all these bloody Glass Breaks looking for one with a vibration detector no wonder i couldnt find one.

i think you've either mis read it or someones pulling your leg.

 

This is what it says on my Spec sheet

Zone 12 Alarm - Area A =  A Dualtechology breakglass vibration detector located on the ceiling at a point of 1.5 meters from the rear and flank walls to detect a force sufficient to break the plate glass windows in the rear & flank walls and gain entry to the seminar room by penetration of the perimiter.

 

This is on the assignment from C&G,

 

their paperwork is ****.  delete vibration from the sentence.  

re impaq. thought it was a vibro?

 

OP your comment is based on a dual tech glass break detector. in theory it is supposed to detect the impact on the glass as a 'thump' then detect the noise of the glass breaking as a 'sssshhhh'

 

The idea of this is to prevent broken bottles etc causing a false alarm.

 

but my advise to your lecturer as it was when i did my 1851 c&g is that breakglass detectors are useless period. they either false alarm or miss genuine alarms.

What would be the point of putting vibration detection on the ceiling? To get a confirmed alarm they would have to break the windows and smash the ceiling. Not seen many breakins where they do that

The rooms that asked for a Glass Break vibration also Have a PIR located in them. It looks like the person at C&G has either typed it wrong or doesnt know what there on about.

 

My teacher has had to re draw the plans/layout they sent as they where asking for detection in rooms that didnt even exist

Sounds like the one writing the papers is the one that needs the training

Honeywell Flexguard ceiling mount it is then, for the quick reply guys, so i am not searching for detectors that dont exist 

i cant seem to source a dualtechnology glass break & vibration detector.

Sentrol, used to do a fitted "on the glass" Break glass / shock sensor which was piezo on a sticky pad ?

Whether these still exist as a EN Graded product ? (****** if I know)

re impaq. thought it was a vibro?

There's a Impaq Breakglass too.

Confusing much like the Impaq Ricochet devices.

Had a shop that used to chase us "children out" many moon ago.

We worked out rattling a set of keys got him out of bed early in the morning

paul can we go back to the steam age alarm?
