Fire Alarm Upgrade

[Redone]

Whilst admiring the plasterer skimming a ceiling at a care home yesterday I noticed that the fire resisting cable (new) from the new detector had been crimped onto the existing PVC from the old system...  Shouldn't the cable run 'complete' now be upgraded/protected?

I'd attach a picture if I knew how?

Also the the installer wants to install sounders in each of the residents bedroom, or he claim's it will not be 'L1'?  

I'm sure this is not a requirement for care homes.  The alarm can be heard in all areas of the building by the staff as is.  He also says a new panel will be required to accomodate the sounders - not the detectors? - about 11 detectors required.

Is it me?
