Hi Guys.

 

Can anyone point me in the direction for obtaining some sort of guide in good old english for Grade 3 installations. Without me obtaining and going through the standard and trying to decipher it does anyone know of a guide that explains everything from Battery backup requirements, SAB monitoring, if specific contacts are required on a specific door i.e non flush on outward opening.

 

If anything exists it would be much appreciated.

 

 

What's the type of contact got to do with grading and what doors it is on?

 

To be honest the requirements are easier in the standard as they are all in pretty little tables.

I was under the impression that with a Flush contact on an outward opening door it could hinder a grade 3 system because of the ability to interfere with it from the outside via the opening leaf. This doesn't mean to say I've stuck to this as of yet because  I've not had to install flush contacts to a G3 System. Mathew I'm purely trying to understand the standard so best practice can be carried out and by publicly asking I'm hoping to achieve the right answers

Irrelevant. As long as it is a grade 3 flush then it's a grade 3 contact. Surface / flush doesn't matter.

 

There is no major difference in the design of a grade 2 or grade 3 system, the difference is that of the components at the end of the wires.

Best place is the standards.

 

Have you seen this.

This may help if you want the real basics, obviously there is more, but this is some of the main stuff.

 

Without wading through everything (I have it all as PDFs) which doc holds all the signalling times for all the grades? Is it in the ENs for alarms or signalling?

Notification options are if i remember in EN50131-1 System Standard Table 10, Annex B also details the reporting times taken from EN50136-1-1

Detector Orientation Adjustment? What is that please?
