Grade 3 with smoke alarms?

As far as fire on a Grade 3, leaving out the issue of 'why is OP doing DIY to G3' I don't see the issue with this as it does not form part of the intrusion detection, it's surely an ancilliary same as connecting a freezer or other technical alarm?

Using all grade 3 kit and installing it to grade 3 is fine but you cant call it grade 3, in the same way as if we installed a grade 3 system and put a grade 2 door contact on it, it then becomes grade 2. Not a problem unless something happens and the insurer wants to see the cert

But fire detectors and freezer alarm contacts are not graded at all, as they are not intruder componenrts to PD6662?

 

I appreciate I am not approved, but surely a graded system doesn't mean you can't have ancilliaries that don't form part of the intruder system?

 

Are there really no Grade 3 (or Grade 2 for that matter) systems out there with technical and freezer alarms attatched?

If a lower graded i&has part is fitted to an i&has then it lowers the overall grade however fitting an unrelated switch to signal something else isn't i&has

Yep just for clarity I'm fine with, and understand that, just confused that we seemed to be saying you basically can't fit ANY ancilliaries or monitored input devices to a graded system.

Ancillaries do not effect the grade of the intruder, grade is effected only by intruder components

Ah fair enough, I thought it was a spazzy typing of IAS

Right thats fine I just thought you were saying something different when you said "Using all grade 3 kit and installing it to grade 3 is fine but you cant call it grade 3,", wrt to fire detectors. Obviously the installation isn't really grade 3 if its DIYed but that's the whole reason I'm still confused why anyone would want to.

Agreed, you can put lipstick on a pig and call it your wife, but its still a pig
